BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates, in general, to medical device packages and. in
particular, to medical device packages for receiving, and securely and removably
retaining, a medical device.
[0003] 2. Description of the Related Art
[0004] A variety of medical devices require packaging to. for example, protect the
medical device from damage prior to use and to maintain sterility of the medical device.
For integrated medical devices that combine a dermal tissue penetration member (e.g., a
lancet or micro-needle) with a test strip, the associated package should provide for an
uncomplicated deployment of the dermal tissue penetration member during use. while
also providing for protection of a user from inadvertent contact with the dermal tissue
penetration member prior and subsequent to use. Furthermore, the packaging should
provide humidity resistance for the test strip during storage.
[0005] Single-use (i.e., disposable) integrated medical devices are illustrative of the
above requirements in that they require a medical device package that maintains
sterility and protects the single-use integrated medical device contained therein from
damage prior to use. Such medical device packages should also provide humidity
resistance and UV protection for a test strip of such single-use integrated medical
devices prior to use. Furthermore, the medical device package should provide for
deployment of a dermal tissue penetration member of such a single-use integrated
medical device during use. as well as for disabling (i.e.. preventing subsequent use) and
safely discarding the single-use integrated medical device following use.
[0006] Conventional medical device packages do not fulfill all or even most of the
requirements described above in a cost effective manner. Still needed in the field.
therefore, is a medical device package that provides a sterility barrier and/or for
protection of a medical device enclosed therein, while also providing for an
uncomplicated deployment of the medical device during use. Furthermore, for
integrated medical devices that include a dermal tissue penetration member (e.g.. a
lancet or micro-needle), a need exists for a medical device package that protects the
dermal tissue penetration member from damage, humidity, and/or contamination prior
to use, that protects a user from accidental contact therewith and that also disables the
medical device following use, thereby preventing its repeated use. In addition, the
materials and methods used to manufacture the medical device package should be cost
effective.
SUMMARY OF THE INVENTION
[0007] Medical device packages according to the present invention provide a sterility
barrier and/or protection for a medical device (e.g., an integrated medical device)
enclosed therein. Embodiments of medical device packages according to the present
invention also provide for an uncomplicated deployment of the medical device during
use. Furthermore, with respect to integrated medical devices that include a dermal
tissue penetration member (e.g., a lancet or micro-needle), medical device packages
according to embodiments of the present invention protect the dermal tissue penetration
member from damage, humidity, and/or contamination prior to use, and protect a user
from accidental contact therewith. Embodiments of the medical device packages
according to the present invention are also adapted to disable the medical device
following use, thereby preventing its repeated use. In addition, due to relative
simplicity of configuration, medical device packages according to the present invention
are cost effective.
[0008] A medical device package according to embodiments of the present invention
includes a main cap member and a minor cap member. The main cap member has a
proximal end, a distal end and a cavity with a cavity opening at the proximal end. The
cavity is configured to receive, and to securely and removably retain, a medical device
(e.g.. an integrated medical device that includes a dermal tissue penetration member
and a test strip) at least partially therein. The minor cap member is configured to seal
the cavity opening once the medical device has been received in the cavity.
[0009] Medical device package kits according to embodiments of the present invention
include a main cap member, a minor cap member and a connector. The main cap
member has a proximal end, a distal end and a cavity. The cavity has a cavity opening
at the proximal end of the main cap member. The cavity is configured to receive, and
to securely and removably retain, a medical device at least partially therein. The minor
cap member is configured to seal the cavity opening once the medical device has been
received in the cavity. The connector is configured to engage the medical device
during removal of the medical device from the cavity.
[0010] Methods according to the present invention enable the uncomplicated
deployment (i.e., extraction) of a medical device from a medical device package.
Methods for extracting a medical device from a medical device package according to
embodiments of the present invention first include providing a medical device package,
with a medical device (e.g., an integrated medical device) therein, and a connector.
The provided medical device package includes a main cap member having a cavity and
proximal and distal ends, and a minor cap member. The cavity of the main cap
member has a cavity opening at the proximal end of the main cap member and is
configured to receive, and to securely and removably retain, the medical device at least
partially therein. The minor cap member is configured to seal the cavity opening.
[0011] The methods also include breaching the minor cap member with the connector
such that at least a portion of the connector enters the cavity. Next, the medical device
is engaged by the connector and extracted from the medical device package.
[0012] Other methods according to the present invention include disabling a medical
device that has been extracted from a medical device package by inserting the medical
device back into a cavity of the medical device package to a position that results in a
disabling of repeated use of the medical device. Such disablement can be obtained by,
for example, a wedging of the medical device into a fixed position within the cavity of
the medical device package.

DETAILED DESCRIPTION OF THE INVENTION
[0042] FIGs. 1. 2A-2D, 3A and 3B are various simplified views of a medical device
package 100 according to an exemplary embodiment of the present invention. Medical
device package 100 includes a main cap member 110 and a minor cap member 150.
[0043] Main cap member 110 includes a cavity 116 therein, a proximal end 112 and a
distal end 114. Cavity 116 has a cavity opening 118 at the proximal end 112 of the
main cap member 110 and is configured to receive, and to securely and removably
retain, a medical device (e.g., integrated medical device 300, illustrated in FIGs. 4A
and 4B), at least partially therein.
[0044] FIGs. 4A and 4B are simplified perspective and side views, respectively, of an
exemplary integrated medical device 300 that can be securely and removably contained
within medical device package 100. Integrated medical device 300 includes a test strip
304 and a dermal tissue penetration member 302, as illustrated in FIGs. 4A-4B. Test
strip 304 has a reaction area (not shown) and electrical contacts 306 that terminate on a
distal end 310 of medical device 300. Electrical contacts 306 are made of any suitable
conductive material, such as carbon. Dermal tissue penetration member 302 includes a
lancet 320 adapted to pierce a user's skin and draw blood into the reaction area of test
strip 304. Further descriptions of integrated medical devices that can be contained
within embodiments of medical device packages according to the present invention are
in International Application No. PCT/GBO 1/05634 (published as WO 02/49507 on June
27, 2002) and U.S. Patent Application No. 10/143,399, both of which are fully
incorporated herein by reference. In addition, dermal tissue penetration member 302
can be fabricated, for example, by a progressive die-stamping technique, as disclosed in
the aforementioned International Application No. PCT/GBO 1/05634 (published as WO
02/49507 on June 27, 2002) and U.S. Patent Application No. 10/143.399.
[0045] Referring again to FIGs. 1, 2A-2D, 3A and 3B, in the embodiment of medical
device package 100, cavity opening 118 is bounded by a rim 120 of sufficient surface
area to enable minor cap member 150 to be adhered to rim 120 by processes known to
those skilled in the art. including, but not limited to, heat sealing processes. In this
manner, minor cap member 150 and main cap member 110 of medical device package
100 provide a sterility barrier and humidity protection for a medical device contained
therein.
[0046] External features of main cap member 110 include a first peripheral edge 122, a
second peripheral edge 124, a main cap upper surface 126 and a main cap lower surface
128. As shown in FIG. 2A, first peripheral edge 122 and second peripheral edge 124
are truncated to end at the distal edge 121 of rim 120. If desired, the first and second
peripheral edges 122, 124 can be asymmetrically disposed about a longitudinal axis of
the main cap member. Such an asymmetric configuration can serve to properly orient
the medical device package during its insertion into a receiving slot of associated
hardware (for example, an analytical meter receiving slot configured to direct the
medical device package to a connector described below with respect to FIGs. 6A-6D).
[0047] As shown in FIGs. 1 and 2A, main cap upper surface 126 optionally includes a
directional marker 130 that is discontinuous with (e.g., raised above or, alternatively,
recessed below) the remainder of main cap upper surface 126. Directional marker 130
may include, but is not limited to, an ellipse 132 and an arrow 134. as depicted in FIGs.
1 and 2A. Directional marker 130 provides a user with both tactile and visual cues for
proper orientation of medical device package 100 during use.
[0048] Cavity 116 is defined (at least in part) by a first smooth inner surface 127 and a
second smooth inner surface 129 and includes first and second lateral channels 140 and
142, respectively, as shown in FIGs. 2C-2D and 3B. In addition, cavity 116 is also
defined by first lateral surface 170 located internally to first peripheral edge 122 and a
second lateral surface 172 located internally to second peripheral edge 124. In the
vicinity of proximal end 112, first lateral surface 170 has a first sloped land 160. and
second lateral surface 172 has a second sloped land 162. First sloped land 160
terminates at the beginning of first lateral channel 140, while second sloped land 162
terminates at the beginning of second lateral channel 142. First lateral channel 140 and
second lateral channel 142 extend about half way along first and second laterals
surfaces 170 and 172, respectively. First and second sloped lands 160, 162 begin at
cavity opening 118, and slope inwardly and distally towards distal end 114 of main cap
member 110.
[0049] First and second lateral channels 140 and 142 "begin at the end of first and
second sloped lands 160 and 162. respectively, and extend approximately half way into
cavity 116. First and second lateral channels 140 and 142 are divided into a post-use
portion 202, a transition point 204, and a pre-use portion 206 (see FIGs. 3A and 3B).
As is evident from FIG. 3B, first lateral channel 140 is the mirror image of second
lateral channel 142. One skilled in the art will recognize from the entirety of the
present disclosure that first and second sloped lands 160, 162, first and second lateral
channels 140, 142, transition point 204, and pre-use portion 206 are configured to
receive, and securely and removably retain, a medical device within cavity 116. In
addition, post-use portion 202 is configured to disable a used medical device (as
explained in detail below with respect to, for example, FIGs. 16A and 16B).
[0050] Main cap member 110 can be formed of any suitable material known to those of
skill in the art including, for example, rigid plastic materials such as polystyrene,
polycarbonate and polyester. Such rigid plastic materials are impervious to puncturing
and to air and/or air-borne bacteria and, therefore, provide a sterility barrier and a
puncture-resistant protective barrier. It can be particularly beneficial in terms of
humidity protection for main cap member 110 to be formed of a desiccant-loaded high-
density polyethylene (e.g., 2AP desiccant-loaded high-density polyethylene,
commercially available from Airsec in France).
[0051] Minor cap member 150 is configured to seal cavity opening 118 once a medical
device has been received in cavity 116. In the embodiment of FIG. 1, minor cap
member 150 is a breachable film such as breachable metallic foil. Other suitable
materials for minor cap member 150 include paper, polymer and Tyvek. However, as
described with respect to other embodiments below, minor cap member 150 can take a
variety of forms, all of which are capable of sealing the cavity opening of an associated
main cap member once a medical device has been at least partially received within the
cavity of the main cap member.
[0052] FIG. 2D is a proximal end perspective view of main cap member 110.
Transition point 204 includes a vertical shoulder 204A and a horizontal shoulder 204B,
as shown in FIG. 2D. Upon insertion of an unused medical device (e.g.. integrated
medical device 300 of FIGs. 4A and 4B prior to use) into cavity 116 of main cap
member 110, vertical shoulder 204A prevents the medical device (not shown) from
being inserting past transition point 204 (see FIGS. 2A and 2B). In other words, the
unused medical device is inserted only to a first position, which is defined by contact of
the unused medical device with transition point 204. However, once a medical device
is used, such a used medical device can be inserted back into cavity 116 of main cap
member 110 for disablement and disposal purposes. In doing so, the used medical
device (e.g., integrated medical device 300 of FIGs. 4A and 4B subsequent to use) is
inserted beyond the first position to a second position, wherein the used medical device
extends past transition point 204 toward distal end 114 and is irreparably damaged (i.e.,
disabled) by horizontal shoulder 204B. Such damage prevents a subsequent removal,
and thus repeated use, of the once used medical device.
[0053] FIGs. 5A-5D are various views of main cap member 100 of FIG. 1 with
integrated medical device 300 of FIGs. 4A and 4B inserted therein prior to use of
integrated medical device 300 (i.e., integrated medical device 300 is "unused"). In
FIGs. 5A-5D, integrated medical device 300 extends between first lateral channel 140
and second lateral channel 142 and lies parallel to first smooth inner surface 127 and
second smooth inner surface 129. Unused integrated medical device 300 is securely
retained within cavity 116 via a friction fit with first lateral channel 140 and second
lateral channel 142. Distal end 310 of integrated medical device 300 remains within
proximal end 112 of medical device package 100 and is not in contact with first lateral
channel 140 and second lateral channel 142. Furthermore, it should be noted that
lancet 320 is within cavity 116 and thus protected from inadvertent damage. Unused
integrated medical device 300 is positioned within first and second lateral channels 140
and 142 such that proximal end 312 of integrated medical device 300 touches, but goes
no further than, transition point 204, and distal end 310 of integrated medical device
300 remains free from contact with first and second lateral channels 140 and 142 in
cavity 116 (see FIGs. 5C and 5D) of main cap member 110.
[0054] FTGs. 6A through 6D depict an exemplary embodiment of a connector 500
adapted to extract integrated medical device 300 from medical device package 100. In
addition, connector 500 can advantageously be used to mechanically and/or manually
manipulate such a medical device once the medical device has been extracted from the
medical device package. For example, connector 500 can be used to transfer a medical
device from a medical device package to a metering system. As will be appreciated by
those skilled in the art, connector 500 may be a component (either a removable
component or a permanently integrated component) of a metering system (e.g., an
analytical meter configured to determine analyte concentrations in biological fluid
samples). Alternatively, connector 500 can be combined with medical device packages
to form a kit according to an exemplary embodiment of the present invention.
[0055] Connector 500 includes a strip extracting member 502 and a connector body
504. In addition, connector 500 includes a proximal end 510, a distal end 512, an upper
surface 514 and a lower surface 516. Connector body 504 includes a connector
directional marker 518 on upper surface 514. Connector directional marker 518
(optional) is discontinuous with (e.g., raised above or recessed below) upper surface
514 of connector 500. Connector directional marker 5 J 8 may include, but is not
limited to, an ellipse 530 and an arrow 532. Connector directional marker 518 provides
a user with both tactile and visual cues for proper orientation of connector 500 when
inserted into medical device package 100.
[0056] Strip extracting member 502 includes a lower strip engaging arm 540, an upper
strip engaging arm 542 and a plurality of strip engaging elements 544, as illustrated in
FIGS. 6C-6D. Connector 500 also includes electrical leads (not shown) for providing
an electrical connection^) between strip engaging elements 544 and an analytical
meter. In addition, strip extracting member 502 includes a vertical barrier 550 that
contacts distal end 310 of integrated medical device 300 when integrated medical
device 300 is engaged by connector 500. Although three strip engaging elements 544
are depicted in FIG. 6D for the purpose of illustration and explanation, strip extracting
member 502 can include any suitable number of strip-engaging elements. Strip
engaging elements 544 are located on inner surface 543 of upper strip engaging arm
542. Strip engaging elements 544 are spring-loaded connections formed, for example,
by being molded into connector 500 by any suitable process known to those skilled in
the art. Strip engaging elements 544 are used to contact test strip 304 of integrated
medical device 300 through electrical contacts 306. One skilled in the art will
recognize that connector 500 can provide electrical communication between test strip

304 and an analytical meter via strip engaging elements 544 and the connector's
electrical leads.
[0057] FIG. 7 is a top view of connector 500 and a proximal end view of main cap
member 110. with dashed vertical lines showing proper alignment of connector 500
during extraction of a medical device. Solids horizontal line 5F-5F indicates width of
the medical device (for example, approximately 5.5 mm), while solid horizontal line
5G-5G indicates the width of strip extracting element 502 (for example, approximately
4.5 mm).
[0058] FIG. 8 is a flow chart illustrating a sequence of steps in a process 800 for
extracting a medical device from a medical device package according to an exemplary
embodiment of the present invention. Process 800 is described below utilizing FIGs.
9A-D (schematic, cross-sectional views depicting various stages of process 800). FIGs.
10A-E (schematic, perspective views depicting various stages of process 800). FIGs.
11A-C (schematic, top cross-sectional views of various stages of process 800) and
FIGs. 12A-C (schematic enlargements of portions of FIGs. 11 A-C, respectively).
[0059] Process 800 includes first providing (i) a medical device package with a minor
cap member and a medical device contained therein and (ii) a connector, as set forth in
step 810 of FIG. 8. One skilled in the art will recognize that the provided medical
device package and connector can be any suitable medical device package according to
the present invention that includes a breachable minor cap member (e.g., the medical
device package of FIG. 1 and any suitable connector according to the present
invention. The provision of an exemplary medical device package and connector are
depicted in FIG. 9A and FIG. 10A, wherein like elements of the medical device
package and connector of earlier figures are identified with like numerals.
[0060] Next, as set forth in step 820. the minor cap member is breached (e.g.. ruptured)
with the connector such that at least a portion of the connector has entered into the
cavity of the main cap member (see FIG. 9B, 10B. 11A and 12A). Subsequently, the
medical device is engaged by the connector (see FIGs. 9C, IOC, 1 IB and 12B), as set
forth in step 830. The force required for the connector to engage with the medical
device is, for example, approximately 2N. The connector and engaged medical device
are then extracted from the cavity of the medical device package, as set forth in step
840 (see FIGs. 9D, 10D-10E, 11C and 12C). Each of the steps of process 800 can be
performed, for example, either manually by a user or with the aid of a mechanical
and/or electrical device.
[0061] It should be noted, that beaching the minor cap member (such as a breachable
film) and engaging the medical device with the connector do not result in the medical
device moving past the transition points 204 of the first and second lateral channels
140, 142 (as depicted in FIGs. 12A and 12B, which correspond to the breaching and
engaging steps of process 800) since the force required to move the medical device past
transition points 204 (e.g., 7N) is significantly greater than the force required to engage
the connector with the medical device (e.g.. 2N). In the embodiment of FIGs. 9A-9D,
10A-10E, 11A-11C and 12A-12C, during the engaging step, strip engaging elements of
the connector engage a test strip 304 of integrated medical device 300 and a vertical
barrier of the connector contacts the distal end of the integrated medical device 300.
The force required for the breaching the minor cap member and engagement of the
medical device can be, for example, in the range of about 1.5 N to 2.5 N.
[0062] Solid line 5F-5F of FIG. 10E represents a dimension that is identical to the
dimension of solid horizontal line 5F-5F of FIG. 7 (i.e.. the width of integrated medical
device 300). Solid line 10H-10H in FIG. 10E represents the width of the medical
device's lancet. Solid line 101-101 of FIG. 10E represents the width of cavity opening
of medical device package, which is larger than the dimension represented by solid line
5F-5F to assure a medical device's smooth insertion into, and removal from the cavity.
[0063] Process 800 can be performed manually or automatically. Furthermore, process
800 can be, for example, performed by an integrated device that combines an analytical
meter and a connector in a configuration that provides for (i) a medical device to be
extracted from a medical device package; (ii) a sample (e.g., a whole blood sample) to
be obtained from a user and (iii) an analytical result (e.g., blood glucose concentration
of the whole blood sample) to determined, all by a single operation of the integrated
device. Mechanical motions may be incorporated into a lancet cocking action, new test
strip deployment and/or ejection.
[0064] FIG. 13 is a flow chart illustrating a sequence of steps in a process 1300 for
extracting a medical device from a medical device package for use and subsequently
disabling the medical device after use according to an exemplary embodiment of the
present invention. Process 1300 is described below utilizing FIGs. 14A-14D
(schematic, cross-sectional views depicting various stages of process 1300), FIGs. 15A-
15D (schematic, perspective views depicting various stages of process 1300) and FIGs.
16A-16B (schematic, top cross-sectional views of a stage of process 1300).
[0065] Process 1300 includes first providing (i) a medical device package with a minor
cap member and a medical device contained therein at a first position and (ii) a
connector, as set forth in step 1310 of FIG. 13. One skilled in the art will recognize
that the provided medical device package and connector can be any medical device
package according to the present invention that includes a breachable minor cap
member (e.g., the medical device package of FIG. 1).
[0066] Next, at step 1320. the minor cap member is breached (e.g., ruptured) with the
connector such that at least a portion of the connector has entered the cavity of the main
cap member. The medical device is then engaged by the connector, as set forth in step
1330. The connector and engaged medical device are then extracted from the cavity of
the medical device package for use. as set forth in step 1340.
[0067] Subsequently, at step 1350, the connector and engaged medical device are
inserted back into a cavity of the medical device package to a second position, whereby
the medical device is disabled from reuse (see FIGs. 14A-14C, 15A-15C and 16A-
16B). The connector is then disengaged from the medical device and withdrawn from

the medical device package, as set forth in step 1360. It is envisioned that during step
1350, the medical device is disabled by virtue of the medical device being wedged into
the cavity such that the force required to remove the medical device from the cavity is
greater than the force required to disengage the connector from the medical device.
Therefore, an attempt to re-extract the medical device with the connector would be
unsuccessful since the connector would become disengaged from the medical device
before sufficient force could be applied to extract the wedged medical device.
[0068] It should be noted that during insertion of the connector and engaged medical
device into the cavity at step 1350, the medical device is inserted to a second position
within post-use portion 202 that is beyond transition points 204 of the first and second
lateral channels (see, in particular, FIG. 16B), i.e., beyond the first position. The force
required to insert the medical device into the medical device package and disable the
medical device is, for example, approximately 7N. As noted above, disablement of the
medical device is a result of the medical device being wedged into the cavity such that
it cannot be re-extracted using the connector.
[0069] FIG. 17 depicts a medical device package 1900 according to another exemplary
embodiment of the present invention. In FIG. 17, dashed lines indicate certain features
that are hidden due to the perspective nature of FIG. 17. In addition, FIG. 17 depicts
the circumstance where a medical device (i.e., integrated medical device 300 of FIGs.
4A and 4B) is retained partially within medical device package 1900. In the
embodiment of FIG. 17, electrical contacts 306 project from the cavity opening and
minor cap member. Since electrical contacts 306 project from both the cavity opening
and the minor cap member, engagement of the electrical contacts with a connector can
be simplified. For example, there is no need to breach or otherwise remove any
component of the medical device package to obtain access to the electrical contacts and
the electrical contacts are free to deflect upon engagement with a connector.
[0070] Medical device package 1900 includes a main cap member 1910 with a
proximal end 1912, a distal end 1914, a cavity 1918 and a cavity opening 1916. Distal

end 1914 is configured to function as a handle during manually removal of medical
device package 1900 from secondary packaging (not illustrated).
[0071] Medical device package 1900 can be constructed, for example, of molded
plastic or other material that is impervious to air and/or air-borne bacteria, to provide a
sterile-protective and puncture-resistant barrier. Suitable materials include, but are not
limited to. polystyrene, polyethylene, polycarbonate and polyester.
[0072] Cavity 1918 of medical device package 1900 is defined by surfaces depicted
with dashed lines in FIG. 17. Cavity opening 1916 is configured to provide for the
placement of dermal tissue penetration member 302 of medical device 300 wholly
within cavity 1918, as shown in FIG. 17. Medical device package 1900 includes
internally disposed ribs I960, located distally to cavity opening 1916. Ribs 1960 serve
to seal cavity 1918 once a medical device has been inserted partially therein, and
provide a sterile and protective barrier for dermal tissue penetration member 302 by
creating a tortuous path between the external environment and the cavity of the medical
device package. Ribs 1960, together with an at least partially inserted medical device,
serve as a minor cap member for medical device package 1900. As an alternative to
ribs 1960, elastomeric o-rings could be employed to seal cavity 1918 once a medical
device has been inserted partially therein, and to provide a sterile and protective barrier
for dermal tissue penetration member 302.
[0073] FIG. 18 is an exploded perspective view of a medical device package 2000
according to yet another exemplary embodiment of the present invention containing a
medical device 300 (as depicted in FIGs. 4A and 4B). Medical device package 2000
includes a main cap member 2010 and a minor cap member 2020. Main cap member
2010 has a proximal end 2012, a distal end 2014, a cavity opening (not shown), and a
cavity (also not shown). The cavity and cavity opening of main cap member 2010 are
configured for placement of a dermal tissue penetration member of an integrated
medical device wholly therein, thus providing a protective barrier for such a dermal
tissue penetration member.

[0074] Minor cap member 2020 has a proximal end 2022. a distal end 2024, a minor
cap opening 2026, and a minor cap cavity (not shown in FIG. 18). Minor cap opening
2026 and the minor cap cavity are configured for the placement of a test strip 304 of an
integrated medical device wholly or partially therein. Furthermore, proximal end 2012
of main cap member 2010 is adapted to fit wholly within minor cap opening 2026 and
the minor cap cavity. Once main cap member 2010 is fit within minor cap opening
2026 and the minor cap cavity, integrated medical device 300 is completely enclosed
and provided with a sterile-protective and moisture-free barrier.
[0075] Both main cap member 2010 and minor cap member 2020 are beneficially
constructed of molded plastic or other rigid material that is impervious to air and/or air-
borne bacteria, to provide a sterile-protective and puncture-resistant barrier. Suitable
materials for main cap member 2010 and minor cap member 2020 include, but are not
limited to. polystyrene, polyethylene, polycarbonate and polyester.
[0076] FIG. 19 is an exploded perspective view of a medical device package 2100
according to yet another exemplary embodiment of the present invention. Medical
device package 2100 includes a main cap member 2110 and a minor cap member 2120.
Main cap member 2110 has a proximal end 2112. a distal end 2114, a cavity opening
2116 and a cavity (not shown). Cavity opening 2116 and the cavity of medical device
package 2100 are configured for placement of a dermal tissue penetration member 302
of an integrated medical device and a minor cap member proximal end 2122 (described
below) wholly therein, thus providing a protective barrier for dermal tissue penetration
member 302.
[0077] Minor cap member 2120 of medical device package 2100 has a proximal end
2122 and a distal end 2124. Moreover, integrated medical device 300 is permanently
attached to minor cap member 2120 at proximal end 2122. The permanent attachment
of such an integrated medical device to minor cap member 2120 is envisioned to
provide handling benefits during use of the integrated medical device. For example,

minor cap member 2120 could be gripped by a meter, with the main cap member then
being easily removed by a user (e.g., by pulling, twisting or snapping) to deploy the
integrated medical device.
[0078] FIGs. 20, 21 and 22 depict the main cap member 2450 of a medical package
device according to yet another exemplary embodiment of the present invention (for
purposes of clarity, the minor cap member of this medical device package is not
illustrated). FIG. 21 depicts an integrated medical device 300 retained within main cap
member 2450 and FIG. 22 depicts an integrated medical device 300 disabled within
main cap member 2450. Main cap member 2450 is identical to main cap member 110
of FIG. 3B, with the exception that main cap member 2450 has a distal end cavity 2452
configured for disablement and disposal of an integrated medical device.
[0079] Those skilled in the art will recognize that embodiments of medical device
packages according to the present invention can be secondarily packaged for single use
in, for example, a vial or cartridge configured for dispensing the medical device
packages. The secondary package may be constructed of material containing desiccant
or may contain separately packaged desiccant for maintaining contents moisture free.
[0080] Once apprised of the present disclosure, one skilled in the art will also
recognize that a variety of medical devices can be beneficially employed with
embodiments of medical device packages according to the present invention. Such
medical devices include, but are not limited to. integrated medical devices that include
a combination of a test strip and a lancet, examples of which are described in the
aforementioned International Application No. PCT/GB01/05634 (published as WO
02/49507 on June 27, 2002) and U.S. Patent Application No. 10/143,399, both of which
are fully incorporated herein by reference. One skilled in the art will also recognize
that such test strips may have, but are not limited to, an electrochemical or photometric
configuration. For illustrative purposes only, medical devices in various figures of the
present disclosure were depicted as having an electrochemical configuration.

[0081] Moreover, those skilled in the art will appreciate that medical device packages
according to embodiments of the present invention can be employed with medical
device adapted for the measurement of, for example, glucose, ketones. glycated
albumin, coagulation parameters and cholesterol of a sample.
[0082] In addition, one skilled in the art will also recognize that medical device
packages according to the present invention may be contained within a combined
sample collection and metering system designed for in-situ testing. Examples of such
systems designed for in-situ testing are disclosed in International Patent Application
No. PCT/USO1/07169 (published as WO 01/64105 Al on September 7, 2001) and
International Patent Application No. PCT/GB02/03772 (published as WO 03/015627
