- the web of material 26 is generally flat, and has an upper face 30 and a lower face 32 .
- the web of material 26 can be comprised of a polymeric film, cloth, nonwoven or the like.
- An adhesive 34 such as a pressure sensitive adhesive, is disposed on the lower face 32 of the web of material 26 .

- Coextruded multilayer polymeric films are also suitable, such as described in U.S. Pat. No. 5,783,269 (Heilmann et al.), the disclosure of which is incorporated herein by reference.
- Layered backings such as polyethylene terephthalate-aluminum-polyethylene composites and polyethylene terephthalate-EVA composites are also suitable.
- Foam tape backings such as closed cell polyolefin films used in 3MTM 1777 Foam Tape and 3MTM 1779 Foam Tape are also suitable.
- Polyethylenes, polyethylene blends, and polypropylenes are preferred polymer films. Polyethylenes and polyethylene blends are most preferred polymer films.

- the container 24 includes a circular central base portion 36 , a sidewall 38 connected at or near the perimeter of the central base portion 36 , and a perimeter lip 40 connected to the sidewall 38 opposite the central base portion 36 .
- a first portion 42 of the perimeter lip 40 is adhesively affixed to the adhesive 34 on the web of material 26 , and a second portion 44 of the perimeter lip 40 is spaced from the adhesive 34 so as not to adhere to it. This creates a gap or slight separation 46 (see FIG. 2 ).
- the gap 46 facilitates separating the container 24 from the patch 22 for application of the patch 22 to a patient.
- a continuous adhesive connection is formed around the microneedle array 28 between the web of material 26 and the perimeter lip 40 of the container 24 . That continuous connection can form a seal.
- the seal may be a hermetic seal, that is, a seal that can prevent entry or escape of air or other vapors, such as moisture vapor. Sealing the microneedle array 28 between the web of material 26 and the container 24 helps protect the microneedle array 28 from contamination and damage prior to deployment.
- the web of material 26 may be considered to be disposed substantially in a first plane and the first portion 42 of the perimeter lip 40 is disposed substantially in a second plane that is generally parallel to the first plane.
- the web 26 and first portion 42 are largely planar, but that minor variations, for example, due to manufacturing imperfections or due to the flexibility in the web and/or the carrier material may cause slight, but insignificant, deviations from planarity.
- the second portion 44 of the perimeter lip 40 is generally not disposed in the second plane.
- the central base portion 36 and the sidewall 38 of the container 24 define a volume in which the microneedle array 28 can rest.
- the container 24 is spaced from the microneedle array 28 , as the microneedle array 28 is generally susceptible to damage from contact during storage, transportation, and at other times prior to deployment.
- the container 24 can have a relatively low profile, such that the sidewall 38 of the container 24 preferably has as small a height, H, as possible without damaging or risking damage to the microneedle array 28 through contact.
- a low profile container 24 reduces space occupied by the cartridge 20 , for storage and transportation purposes, while still providing protection to the microneedle array 28 .
- a low profile container 24 also reduces the amounts of gases (i.e., air) and contaminants that are exposed to the microneedle array 28 and molecules carried thereon. Because many molecules intended for delivery with the microneedle array 28 can have limited lifespans and may be sensitive to contamination and deterioration, a low profile container 24 reduces the volume of air that is exposed to the microneedle array 28 to limit such negative effects.
- a suitable low-profile height will depend upon the nature of the patch 22 and microneedle array 28 , but the height will typically be less than 2.0 cm, often less than 1.5 cm, and sometimes less than 1.0 cm.
- the container 24 can be formed of a polymer material. Generally, a rigid material is selected in order to better protect the microneedle array 28 from damage and to facilitate storage (e.g., for stacking a plurality of microneedle cartridges 20 ). In one embodiment, the container 24 is a transparent or translucent material. In one embodiment, the container 24 is opaque to protect the microneedle array 28 from exposure to light.

Description
- The present application claims priority to U.S. Provisional Application Ser. No. 60/694,446, filed on Jun. 27, 2005, which is incorporated herein in its entirety.
- The present invention relates to microneedle array cartridges.
- Only a limited number of molecules with demonstrated therapeutic value can be transported through the skin via unassisted or passive transdermal drug delivery. The main barrier to transport of molecules through the skin is the stratum corneum (the outermost layer of the skin).
- Devices including arrays of relatively small structures, sometimes referred to as microneedles or micro-pins, have been disclosed for use in connection with the delivery of therapeutic agents and other substances through the skin and other surfaces. The devices are typically pressed against the skin in an effort to pierce the stratum corneum. The microneedle arrays are generally used once and then discarded.
- Microneedles on these devices pierce the stratum corneum upon contact, making a plurality of microscopic slits that serve as passageways through which molecules of active components (e.g., therapeutic agents, vaccines, and other substances) can be delivered into the body. In delivering an active component, the microneedle array can be provided with a reservoir for temporarily retaining an active component in liquid form prior to delivering the active component through the stratum corneum. In some constructions, the microneedles can be hollow to provide a liquid flow path directly from the reservoir and through the microneedles to enable delivery of the therapeutic substance through the skin. In alternate constructions, active component(s) may be coated and dried on the microneedle array and delivered directly through the skin after the stratum corneum has been punctured.
- Transdermal adhesive patches are also available and are generally constructed as an adhesive article with a pressure sensitive adhesive coated onto the surface of a backing comprised of a polymeric film, cloth or the like. Transdermal adhesive patches are provided with an adhesive that allows the patch to be releasably adhered to the surface of the skin where a predetermined dosage of an active component can be put in contact with a small surface area of the skin. An appropriate biocompatible carrier is normally provided to facilitate the absorption of molecules through the stratum corneum over a period of time while the patch remains adhered to the skin.
- Patches, with or without a microneedle array, can have fragile and sanitary characteristics. It is generally desired that the patch and array not be contacted before application to a target site. This presents difficulties in storing and transporting patches to desired locations for eventual application. In addition, providing collars or other protection for microneedle arrays produces bulky structures that require excessive amounts of materials to manufacture and take up large amounts of space during transportation and storage. Moreover, loading a microneedle array on an applicator device can also be time consuming and difficult for operators. Thus, the present invention provides an alternative microneedle cartridge design.
- In a first aspect of the present invention, a microneedle array cartridge includes a web of material having a top face and an opposite bottom face. An adhesive and a microneedle array are disposed on the bottom face of the web of material. A container is disposed relative to the bottom face of the web of material, and has a perimeter portion and a central portion for covering at least part of the microneedle array. At least part of the perimeter portion of the container contacts the adhesive, and the central portion of the container does not contact the adhesive.

The figures may not be drawn to scale. Like reference numbers have been used throughout the figures to denote like parts.
- Patches can be used for transdermal delivery of molecules, and can carry microneedle arrays, which have utility for the delivery of large molecules that are ordinarily difficult to deliver by passive transdermal delivery. As used herein, “array” refers to the medical devices described herein that include one or more structures capable of piercing the stratum corneum to facilitate the transdermal delivery of therapeutic agents or the sampling of fluids through or to the skin. “Microstructure,” “microneedle” or “microarray” refers to the specific microscopic structures associated with the array that are capable of piercing the stratum corneum to facilitate the transdermal delivery of therapeutic agents or the sampling of fluids through the skin. By way of example, microstructures can include needle or needle-like structures as well as other structures capable of piercing the stratum corneum. The microneedles are typically less than 500 microns in height, and sometimes less than 300 microns in height. The microneedles are typically more than 20 microns in height, often more than 50 microns in height, and sometimes more than 125 microns in height.

FIG. 1 is a perspective view of a first embodiment of amicroneedle cartridge 20 that includes apatch 22 and acontainer 24.FIG. 2 is a cross-sectional view of themicroneedle cartridge 20. Thepatch 22 shown inFIGS. 1 and 2 includes a web ofmaterial 26 that forms a backing, and amicroneedle array 28 supported by and attached to the web ofmaterial 26. The web ofmaterial 26 is generally flat, and has anupper face 30 and alower face 32. The web ofmaterial 26 can be comprised of a polymeric film, cloth, nonwoven or the like. An adhesive 34, such as a pressure sensitive adhesive, is disposed on thelower face 32 of the web ofmaterial 26. Themicroneedle array 28 is located relative to thelower face 32 of the web ofmaterial 26 at a generally central portion of the web ofmaterial 26, which has a circular shape. Themicroneedle array 28 can be attached to the web ofmaterial 26, for example, by adhesive, welding, heat bonding, and can be formed integrally with the web ofmaterial 26. - Suitable materials for the
microneedle array 28 include those selected from materials such as acrylonitrile-butadiene-styrene (ABS) polymers, polyphenyl sulfides, polycarbonates, polypropylenes, acetals, acrylics, polyetherimides, polybutylene terephthalates, polyethylene terephthalates as well as other known materials and combinations of two or more of the foregoing. Themicroneedle array 28 can carry molecules for eventual delivery through the stratum corneum of a patient's skin (i.e., the skin of a human or non-human test subject). Those molecules can be therapeutic agents, vaccines, and other materials. A reservoir can be included with themicroneedle array 28 for holding molecules for eventual delivery. Deployment of thepatch 22 to a target site permits the molecules to be delivered through or to the stratum corneum. - The adhesive layer will generally be selected according to the desired end use of the articles prepared by the present method. Examples of suitable adhesives include acrylates, silicones, polyisobutylenes, synthetic rubber, natural rubber, and copolymers and mixtures thereof. Further description of suitable adhesives may be found in U.S. Pat. Nos. 5,656,286 (Miranda et al.), 4,693,776 (Krampe et al.), 5,223,261(Nelson et al.), and 5,380,760 (Wendel et al.) the disclosures of which are incorporated herein by reference.
- Typical examples of flexible films employed as conventional tape backings which may be useful as a backing film include those made from polymer films such as polypropylene; polyethylene, particularly low density polyethylene, linear low density polyethylene, metallocene polyethylenes, and high density polyethylene; polyvinyl chloride; polyester (e.g., polyethylene terephthalate); polyvinylidene chloride; ethylene-vinyl acetate (EVA) copolymer; polyurethane; cellulose acetate; and ethyl cellulose. Coextruded multilayer polymeric films are also suitable, such as described in U.S. Pat. No. 5,783,269 (Heilmann et al.), the disclosure of which is incorporated herein by reference. Layered backings such as polyethylene terephthalate-aluminum-polyethylene composites and polyethylene terephthalate-EVA composites are also suitable. Foam tape backings, such as closed cell polyolefin films used in 3M™ 1777 Foam Tape and 3M™ 1779 Foam Tape are also suitable. Polyethylenes, polyethylene blends, and polypropylenes are preferred polymer films. Polyethylenes and polyethylene blends are most preferred polymer films. In one embodiment, the backing film is translucent or transparent. Additives may also be added to the backing film, such as tackifiers, plasticizers, colorants, and anti-oxidants.
- The
container 24 is removably attached to thepatch 22 to cover themicroneedle array 28. Thecontainer 24 includes a circularcentral base portion 36, asidewall 38 connected at or near the perimeter of thecentral base portion 36, and aperimeter lip 40 connected to thesidewall 38 opposite thecentral base portion 36. Afirst portion 42 of theperimeter lip 40 is adhesively affixed to the adhesive 34 on the web ofmaterial 26, and asecond portion 44 of theperimeter lip 40 is spaced from the adhesive 34 so as not to adhere to it. This creates a gap or slight separation 46 (seeFIG. 2 ). Thegap 46 facilitates separating thecontainer 24 from thepatch 22 for application of thepatch 22 to a patient. However, in one embodiment, a continuous adhesive connection is formed around themicroneedle array 28 between the web ofmaterial 26 and theperimeter lip 40 of thecontainer 24. That continuous connection can form a seal. In some instances, the seal may be a hermetic seal, that is, a seal that can prevent entry or escape of air or other vapors, such as moisture vapor. Sealing themicroneedle array 28 between the web ofmaterial 26 and thecontainer 24 helps protect themicroneedle array 28 from contamination and damage prior to deployment. In such a configuration the web ofmaterial 26 may be considered to be disposed substantially in a first plane and thefirst portion 42 of theperimeter lip 40 is disposed substantially in a second plane that is generally parallel to the first plane. It should be understood by the term disposed substantially in a plane, that theweb 26 andfirst portion 42 are largely planar, but that minor variations, for example, due to manufacturing imperfections or due to the flexibility in the web and/or the carrier material may cause slight, but insignificant, deviations from planarity. Thesecond portion 44 of theperimeter lip 40 is generally not disposed in the second plane. - As shown, the shape of the container is a cylinder, but it should be understood that other shapes are suitable as long as the base portion is appropriately spaced from the
microneedle array 28. For example, thecentral base portion 36 andsidewall 38 may have the form of a dome, in which case there may be no discernable boundary between thesidewall 38 and thecentral base portion 36. The sidewalls may be angled and in some embodiments may extend until they contact an opposing sidewall, for example, forming a cone-shaped container. Furthermore, the container may have additional exterior protrusions or indentations to facilitate handling and/or storage. For example, a handling tab may be affixed to the exterior surface of the base portion to make the container more easily graspable. - The
central base portion 36 and thesidewall 38 of thecontainer 24 define a volume in which themicroneedle array 28 can rest. Thecontainer 24 is spaced from themicroneedle array 28, as themicroneedle array 28 is generally susceptible to damage from contact during storage, transportation, and at other times prior to deployment. Thecontainer 24 can have a relatively low profile, such that thesidewall 38 of thecontainer 24 preferably has as small a height, H, as possible without damaging or risking damage to themicroneedle array 28 through contact. Alow profile container 24 reduces space occupied by thecartridge 20, for storage and transportation purposes, while still providing protection to themicroneedle array 28. Alow profile container 24 also reduces the amounts of gases (i.e., air) and contaminants that are exposed to themicroneedle array 28 and molecules carried thereon. Because many molecules intended for delivery with themicroneedle array 28 can have limited lifespans and may be sensitive to contamination and deterioration, alow profile container 24 reduces the volume of air that is exposed to themicroneedle array 28 to limit such negative effects. A suitable low-profile height will depend upon the nature of thepatch 22 andmicroneedle array 28, but the height will typically be less than 2.0 cm, often less than 1.5 cm, and sometimes less than 1.0 cm. - The
container 24 can be formed of a polymer material. Generally, a rigid material is selected in order to better protect themicroneedle array 28 from damage and to facilitate storage (e.g., for stacking a plurality of microneedle cartridges 20). In one embodiment, thecontainer 24 is a transparent or translucent material. In one embodiment, thecontainer 24 is opaque to protect themicroneedle array 28 from exposure to light. -
FIG. 3 is a partial cross-sectional view of themicroneedle cartridge 20 held on anapplicator device 50. As shown inFIG. 3 , theapplicator device 50 has a skin-contactingface 52, arecess 54, a substantiallycircular opening 56 defined in abottom portion 58 of therecess 54, and a pair ofretainer members 60 that each have substantially flat upper surfaces 62. Theretainer members 60 are generally elongate and their substantially flatupper surfaces 62 are generally parallel to and facing thebottom portion 58 of therecess 54. The pair ofretainer members 60 are located at opposite portions of theopening 56 and are connected at one side of therecess 54. Theretainer members 60 define an opening at one end for accepting patches between theretainer members 60 and thebottom portion 58 of therecess 54. The upper surfaces 62 of theretainer members 60 may be non-stick or release surfaces. A non-stick or release surface can be achieved, for example, by a non-stick or release coating applied to the upper surfaces 62. The non-stick or release coating can be selected according to the desired use of theapplicator device 50. For instance, a release coating, such as a low surface energy silicone, fluoropolymer, or fluoro-silicone release coating, can be selected based upon the adhesives used with patches applied using thepatch application device 50 - As shown in
FIG. 3 , thepatch 22 is disposed between theretainer members 60 and thebottom portion 58 of therecess 54. Themicroneedle array 28 carried by thepatch 22 faces away from opening 56 in theapplicator device 50. Thepatch 22 contacts theupper surfaces 62 of theretainer members 60, but generally does not adhere firmly to theretainer members 60 due to the non-stick or release character of the upper surfaces 62. -
FIG. 4 is a perspective view of thepatch 22 mounted on theapplicator device 50. In a fully mounted position, as shown inFIG. 4 , thepatch 22 is generally aligned relative to theopening 56 in the applicator device 50 (theopening 56 is not visible inFIG. 4 ). Theretainer members 60 havecutaway portions 64 that provide an enlarged, partially circular open region that is generally aligned with theopening 56 on thebottom portion 58 of therecess 54. The open region defined by thecutaway portions 64 facilitates patch application by reducing the amount of deflection of thepatch 22 required to move thepatch 22 from a mounted position on theapplicator device 50 to a target location, during deployment. Further details of applicators suitable for use with microneedle array cartridges of the present invention may be found in U.S. Patent Application Ser. No. 60/694,447 (Attorney Docket No. 60874US002) filed on Jun. 27, 2005, the disclosure of which is hereby incorporated by reference. - The
microneedle cartridge 20 allows for simple and easy mounting of thepatch 22 to theapplicator device 50, for eventually applying the microneedle array 28 (thearray 28 is not visible inFIG. 4 ) to a target site. Mounting themicroneedle patch 22 on theapplicator device 50 includes the following steps. First, themicroneedle cartridge 20, with thecontainer 24 affixed thereto, is partially slid onto theretainer members 60. Ends of theretainer members 60 are positioned in thegap 46 formed between the web ofmaterial 26 and theperimeter lip 40 of thecontainer 24 of themicroneedle cartridge 20. Then themicroneedle cartridge 20 is slid further along theretainer members 60, simultaneously separating thecontainer 24 from the web ofmaterial 26, until thepatch 22 is fully mounted on the applicator device 50 (e.g., such that themicroneedle array 28 is aligned with theopening 56 defined in thebottom portion 58 of the recess 54). Thecontainer 24 is removed from (i.e., separated from) thepatch 22 to uncover and expose themicroneedle array 28 prior to microneedle deployment. An operator may need to pull thecontainer 24 away from the applicator device 50 (e.g., by applying a force perpendicular to the skin-contactingface 52 of the applicator device 50) in order to fully separate thecontainer 24 from thepatch 22, during the process of mounting or once mounted onto an applicator device. The motion between themicroneedle cartridge 20 and theapplicator device 50 is a relative motion which may be accomplished by moving one or both of theapplicator device 50 and themicroneedle cartridge 20. In one embodiment, a mountingfixture 100 may be used to assist in mounting thepatch 22 of themicroneedle cartridge 20 to theapplicator device 50. A perspective view of the bottom of a mountingfixture 100 is shown inFIG. 13 . The mountingfixture 100 comprisesalignment members 110 andcartridge holder members 120. The cartridge 20 (shown in more detail inFIG. 14 ) includes apatch 22 and acontainer 24. Thepatch 22 includes a web ofmaterial 26 that forms a backing, and a microneedle array 28 (not shown) supported by and attached to the web ofmaterial 26. An adhesive 34, such as a pressure sensitive adhesive, is disposed on thelower face 32 of the web ofmaterial 26. Thecontainer 24 is removably attached to thepatch 22 to cover themicroneedle array 28. Thecontainer 24 includes an asymmetriccentral base portion 36, asidewall 38 connected at or near the perimeter of thecentral base portion 36, and aperimeter lip 40 connected to thesidewall 38 opposite thecentral base portion 36. Asecond portion 44 of theperimeter lip 40 is spaced from the adhesive 34 so as not to adhere to it. This creates a gap orslight separation 46. Thegap 46 facilitates separating thecontainer 24 from thepatch 22 for application of thepatch 22 to a patient. The asymmetric shape of thecentral base portion 36 may be selected so as to mate with the opening provided by thecartridge holder members 120 in an orientation that presents thegap 46 to the front of the mountingfixture 100. This prevents the user from accidentally misaligning thegap 46 with respect to theapplicator device 50. - The mounting
fixture 100 with mountedcartridge 20 is shown partially mated with anapplicator device 50 inFIGS. 15 and 16 . The alignment guides 110 contact anouter recess 55, thus providing for alignment of thecartridge 20 with theretainer members 60 of theapplicator 50. The mounting fixture may be used to fully insert thecartridge 20 into theapplicator 50, at which time the mountingfixture 100 andcontainer 24 may be removed, thereby leaving thepatch 22 mounted in theapplicator 50. In one embodiment, the mounting fixture may be easily grasped by a user or otherwise fixed in space, so that the user may bring theapplicator 50 towards the stationary mounting fixture to load thepatch 22 into theapplicator 50. For example, the mountingfixture 100 may be part of a base station that holdsmultiple cartridges 20 and advances them to thecartridge holder members 120 one at a time. In another embodiment, the mountingfixture 100 may be integrated with packaging material used to hold one ormore cartridges 20. For example, a box of cartridges may have a mounting fixture affixed to an outside surface so that a user could remove a cartridge from the box, place the cartridge in the mounting fixture, and load the cartridge into the applicator as described above. In still another embodiment, a tray holding multiple cartridges could be provided, wherein each cartridge is held in a mounting fixture integrally molded into the tray. Thus each cartridge could be directly loaded from the tray into an applicator. - The mounting configuration shown in
FIGS. 3 and 4 is provided by way of example, and not limitation. In further embodiments, other means of mounting a patch on the applicator device can be used. For instance, in further embodiments, one or more patches can be stored inside theapplicator device 50 prior to application, and then dispensed for application to a target site. -
FIGS. 5-8 show a second embodiment of amicroneedle cartridge 70.FIG. 5 is a perspective view of themicroneedle cartridge 70.FIG. 6 is a front cross-sectional view of themicroneedle cartridge 70, andFIG. 7 is a side cross-sectional view of themicroneedle cartridge 70.FIG. 8 is a bottom view of themicroneedle cartridge 70. - The
microneedle cartridge 70 includes apatch 22 and acontainer 24. Thepatch 22 includes a web ofmaterial 26, amicroneedle array 28 and an adhesive 34 on abottom face 32 of the web ofmaterial 26, and is generally similar to that shown and described with respect toFIGS. 1-4 above. Thecontainer 24 is removably attached to thepatch 22 to cover themicroneedle array 28. Thecontainer 24 includes a circularcentral base portion 36, asidewall 38 connected at or near the perimeter of thecentral base portion 36, and aperimeter lip 40 connected to thesidewall 38 opposite thecentral base portion 36. A pair ofopposed cutouts 72 are provided in theperimeter lip 40. Thecutouts 72 in theperimeter lip 40 make thecontainer 24 smaller than a width or diameter of thepatch 22 in particular regions, and expose portions of the adhesive 34 on thebottom face 32 of the web ofmaterial 26. - A pair of
stiffeners 74 are provided on anupper face 30 of the web ofmaterial 26. Thestiffeners 74 provide additional rigidity to thepatch 22 in order to reduce flexing, bending and other undesired deformation of themicroneedle array 28 prior to and during handling and deployment. In particular, thestiffeners 74 will reduce flexing in the area of thepatch 22 that is suspended above thecentral base portion 36. As shown inFIGS. 6-8 , thestiffeners 74 are parallel to each other and generally aligned relative to thesidewall 38 of thecontainer 24. In further embodiments, more orfewer stiffeners 74 can be provided. Furthermore, thestiffeners 74 can be provided at different locations on thepatch 22 than those shown inFIGS. 6-8 . It should be understood that thestiffeners 74 are optional and that in certain embodiments thepatch 22 may have sufficient resistance to bending or flexing without the need foradditional stiffeners 74. For example, themicroneedle array 28 may extend near or up to the inner surface of thesidewalls 38 and thereby provide sufficient rigidity in the suspended portion of thepatch 22. -
FIG. 9 is a perspective view of a third embodiment of amicroneedle cartridge 80.FIG. 10 is a cross-sectional view of themicroneedle cartridge 80. As shown inFIGS. 9 and 10 , themicroneedle cartridge 80 includes apatch 22 and acontainer 24. Thepatch 22 includes a web ofmaterial 26, amicroneedle array 28 and an adhesive 34 on abottom face 32 of the web ofmaterial 26, and is generally similar to those shown and described with respect toFIGS. 1-8 above. The container is removably attached to thepatch 22 to cover themicroneedle array 28. Thecontainer 24 includes a circularcentral base portion 36, asidewall 38 connected at or near the perimeter of thecentral base portion 36, and aperimeter lip 40 connected to thesidewall 38 opposite thecentral base portion 36. Agasket 82 is disposed to adhere to thelip 40 of thecontainer 24 and patch (i.e., to the web ofmaterial 26 or the adhesive 34). Thegasket 82 is disposed in a substantially continuous band around themicroneedle array 28 in order to form a seal between thepatch 22 and thecontainer 24. In one embodiment, thegasket 82 is an adhesive. In one embodiment a different adhesive may be used for the gasket than that used for the adhesive 34 adhered to thebottom face 32 of the web ofmaterial 26. - Inserting the
cartridge 80 into an applicator device can be generally similar to that described above with respect toFIGS. 1-8 . Additionally, the seal formed by thegasket 82 can be broken during an inserting procedure. For example, an operator can rotate thecartridge 80 relative to an applicator device to slice or otherwise break the seal using a blade or other means disposed on the applicator device. - A plurality of individual microneedle cartridges can be arranged as a package for providing advantages in storage, transportation and dispensing them.
FIG. 11 is a perspective view of a number ofmicroneedle cartridges 90 arranged as asheet 92. Thesheet 92 includes aliner 94 on which thecartridges 90 are carried. Theindividual cartridges 90 can be removably adhered to theliner 94, or secured together by other methods. In some embodiments,perforations 96 can be provided in theliner 94 for separatingindividual cartridges 90. -
FIG. 12 is a side view of a number ofmicroneedle cartridges 90 arranged as aroll 98. Theroll 98 includes aliner 94 on which thecartridges 90 are carried and acore 99 around which theliner 94 is wound. Theindividual cartridges 90 can be removably adhered to theliner 94, or secured together by other methods. In some embodiments,perforations 96 can be provided in theliner 94 for separatingindividual cartridges 90. - The packages shown and described with respect to
FIGS. 11 and 12 permit storage of a plurality of cartridges in close proximity to each other. Individual cartridges can be separated from the others as desired for use. Those packages can also help reduce time between microneedle array deployments, by facilitating “reloading” of applicator devices between array deployments. - Applicators used to apply a microneedle array or patch will typically accelerate the microneedle device to reach a desired velocity that is effective to pierce the microneedles into the skin. The desired velocity is preferably controlled to limit or prevent stimulation of the underlying nerve tissue. The maximum velocity achieved by the microneedle array upon impact with the skin is often 20 meters per second (m/s) or less, potentially 15 m/s or less, and possibly 10 m/s or less. In some instances, the maximum velocity be 8 m/s or less. In other instances, the minimum velocity achieved by the microneedle array upon impact with the skin is often 2 m/s or more, potentially 4 m/s or more, and possibly 6 m/s or more.
- The microneedle arrays useful in the various embodiments of the invention may comprise any of a variety of configurations, such as those described in the following patents and patent applications, the disclosures of which are herein incorporated by reference. One embodiment for the microneedle arrays comprises the structures disclosed in U.S. Patent Application Publication No. 2003/0045837. The disclosed microstructures in the aforementioned patent application are in the form of microneedles having tapered structures that include at least one channel formed in the outside surface of each microneedle. The microneedles may have bases that are elongated in one direction. The channels in microneedles with elongated bases may extend from one of the ends of the elongated bases towards the tips of the microneedles. The channels formed along the sides of the microneedles may optionally be terminated short of the tips of the microneedles. The microneedle arrays may also include conduit structures formed on the surface of the substrate on which the microneedle array is located. The channels in the microneedles may be in fluid communication with the conduit structures. Another embodiment for the microneedle arrays comprises the structures disclosed in U.S. Patent Application Publication No. 2005/0261631, which describes microneedles having a truncated tapered shape and a controlled aspect ratio. Still another embodiment for the microneedle arrays comprises the structures disclosed in U.S. Pat. No. 6,091,975 (Daddona, et al.) which describes blade-like microprotrusions for piercing the skin. Still another embodiment for the microneedle devices comprises the structures disclosed in U.S. Pat. No. 6,313,612 (Sherman, et al.) which describes tapered structures having a hollow central channel. Still another embodiment for the micro arrays comprises the structures disclosed in U.S. Pat. No. 6,379,324 (Gartstein, et al.) which describes hollow microneedles having at least one longitudinal blade at the top surface of tip of the microneedle.
- Microneedle patches of the present invention may be used to deliver drugs (including any pharmacological agent or agents) through the skin in a variation on transdermal delivery, or to the skin for intradermal or topical treatment, such as vaccination.
- In one aspect, drugs that are of a large molecular weight may be delivered transdermally. Increasing molecular weight of a drug typically causes a decrease in unassisted transdermal delivery. Microneedle arrays of the present invention have utility for the delivery of large molecules that are ordinarily difficult to deliver by passive transdermal delivery. Examples of such large molecules include proteins, peptides, nucleotide sequences, monoclonal antibodies, DNA vaccines, polysaccharides, such as heparin, and antibiotics, such as ceftriaxone.
- In another aspect, microneedle patches of the present invention may have utility for enhancing or allowing transdermal delivery of small molecules that are otherwise difficult or impossible to deliver by passive transdermal delivery. Examples of such molecules include salt forms; ionic molecules, such as bisphosphonates, preferably sodium alendronate or pamedronate; and molecules with physicochemical properties that are not conducive to passive transdermal delivery.
- In another aspect, microneedle patches of the present invention may have utility for enhancing delivery of molecules to the skin, such as in dermatological treatments, vaccine delivery, or in enhancing immune response of vaccine adjuvants.
- Microneedle patches may be used for immediate delivery, that is where they are applied and immediately removed from the application site, or they may be left in place for an extended time, which may range from a few minutes to as long as 1 week. In one aspect, an extended time of delivery may be from 1 to 30 minutes to allow for more complete delivery of a drug than can be obtained upon application and immediate removal. In another aspect, an extended time of delivery may be from 4 hours to 1 week to provide for a sustained release of drug.
- Although the present invention has been described with reference to several alternative embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention. For instance, various types of microneedle arrays can be utilized according to the present invention, as well as various types of microneedle applicator devices.
