Description

[Technical field]

[0001] Various embodiments of the present disclosure relate to packaging for medical devices. In particular, embodiments of the present disclosure relate to blister packaging having a protrusion, e.g., a dome-shaped portion, a bulbous portion, or a raised portion, which is connected to the base of the packaging and extends away from the device when the device is placed in the blister packaging. The protrusion can be used to eject the device from the blister packaging. In particular, the protrusion can be used to flex the blister packaging to remove a syringe, e.g., a pre-filled syringe, from the blister packaging. [Background technology]

[0002] Many medical devices are packaged, for example, for distribution and storage to or from a medical facility. When a medical provider is ready to use the medical device, the medical device is removed from the packaging and prepared for use on a patient, as needed. To remove the medical device from the packaging, the user must often directly handle the device, using their hands to push, pull, lift, slide, or otherwise directly touch the medical device. In some cases, it may be undesirable to handle the medical devices excessively when removing them from their packaging, for example, for sterility reasons or to limit damage to the medical device. For example, syringes, particularly pre-filled syringes, may become contaminated when handled during removal of the packaging, compromising the sterility of the syringe body, needle, needle attachment, and / or any medication or other fluid contained therein. If the prefilled syringe is an ophthalmic syringe, handling during removal from the packaging may lead to contamination of the syringe and / or the medication, which may lead to infectious inflammation of the eye, e.g., intraocular infections, such as endophthalmitis after injection. Additionally, for prefilled syringes, handling of the syringe may compromise the accuracy of the dose, e.g., if the syringe plunger is bumped during removal from the packaging. For ophthalmic syringes, dose accuracy may be more critical because the size of the dose may be relatively small, e.g., 20 ml or less, 15 ml or less, 10 ml or less, 0.5 ml or less, or 1 ml or less. For example, the dose may be 200 μl or less, 150 μl or less, or 100 μl or less. Thus, there is a need for medical device packaging that reduces the amount of direct handling of medical devices, particularly prefilled ophthalmic syringes, during removal from the packaging. Summary of the Invention

[0003] According to one aspect of the disclosure, a package for a sterile syringe having a nominal size of less than 1 mL may include a tray having a cavity for receiving the syringe. The cavity may include an opening, one or more side walls, and a base. A lip may surround the opening and may extend radially outward from the cavity and may define a perimeter of the tray. A removable cover may have a perimeter bonded to the lip, and the removable cover may be permeable to a gaseous sterilant, including one or more of vaporized hydrogen peroxide or ethylene oxide. A protrusion may be continuous with the base of the cavity and may extend away from the base of the cavity in a direction opposite the opening of the cavity. The protrusion may be made of a deformable material.

[0004] Various embodiments of the packaging may include one or more of the following aspects: the protrusion may be dome-shaped and the diameter of the base of the dome-shaped protrusion may be about 10 mm to 20 mm; the cavity may include three cavity portions arranged in series along the longitudinal axis of the tray and the three cavity portions may be connected to each other via a narrowing portion; the protrusion may be continuous with a middle cavity portion of the three cavity portions; the tray may be formed from a suitable thermoplastic material including one or more of polypropylene, polystyrene, polyethylene, polycarbonate, polyvinyl chloride, or polyethylene terephthalate glycol; the sterile silicone may be formed from a suitable thermoplastic material including one or more of polypropylene, polystyrene, polyethylene, polycarbonate, polyvinyl chloride, or polyethylene terephthalate glycol; When the sterile syringe is received within the cavity, the height of the protrusion from the apex of the protrusion to the base of the protrusion may be about 5mm to 6mm and the distance between the base of the protrusion and the portion of the syringe covering the protrusion may be about 3mm to 4mm; the sterile syringe may be a pre-filled syringe; the tray may include at least two geometric features located on at least one side wall of the packaging to hold the syringe within the cavity by friction fit, or the tray may include a third geometric feature located at the base of the cavity below where the sterile syringe will be received within the cavity.

[0005] In another aspect, the disclosure includes a package comprising a tray having an opening and a cavity, the cavity including a plurality of side walls and a base. A sterile syringe may be housed within the cavity, and the sterile syringe may be pre-filled with a medicament. A bulbous protrusion may be associated with the tray at a location along a portion of the sterile syringe. In a first state, the bulbous protrusion may extend away from the sterile syringe in a direction opposite the opening of the cavity, and in a second state, the bulbous protrusion may be inverted such that a portion of the bulbous protrusion extends along the bulbous protrusion toward a portion of the sterile syringe. The bulbous protrusion may be configured to transition from the first state to the second state when pressure is applied.

[0006] Various embodiments of the packaging may include one or more of the following aspects: the bulbous protrusion may be under the barrel of the sterile syringe when in the first state, the cavity may include three cavity portions, a first cavity portion housing the plunger of the sterile syringe, a second cavity portion housing the barrel of the sterile syringe, and a third cavity portion housing a distal portion of the sterile syringe, the three cavity portions may be connected to each other by an intermediate narrowed portion, and the sterile syringe may extend through the narrowed portion, the narrowed portion retaining the sterile syringe within the cavity by a friction fit. the packaging may include a removable cover sealing the opening of the cavity opposite the base, the removable cover may be permeable to the gaseous sterilant and configured to maintain a sterile barrier, or the agent may be any one of aflibercept, ranibizumab, bevacizumab, conbercept, OPT-302, RTH258 (brolucizumab), PEGylated designed ankyrin repeating protein (DARPin), or RG7716.

[0007] In another aspect, the disclosure relates to a method of removing an external sterile syringe from a package. The method may include peeling a removable cover from a blister pack tray having a cavity configured to receive the external sterile syringe, the blister pack tray including a dome-shaped protrusion that is connected to a base of the cavity of the blister pack tray and aligned with the external sterile syringe. The method may further include pushing a portion of the dome-shaped protrusion toward the cavity of the blister pack tray, the pushing of the portion of the dome-shaped protrusion bending the portion of the blister pack tray. The method may also include orienting the blister pack tray such that an opening of the cavity faces a sterile surface to eject the external sterile syringe from the blister pack tray onto the sterile surface.

[0008] Various embodiments of the method may include one or more of the following aspects: the external sterile syringe may be pre-filled with aflibercept, ranibizumab, bevacizumab, conbercept, OTP-302, RTH258 (brolocizumab), PEGylated designed ankyrin repeat protein (DARPin), or RG7716, the blister packaging tray may be manufactured from a material including one or more of polypropylene, polystyrene, polyethylene, polycarbonate, polyvinyl chloride, or polyethylene terephthalate glycol, the removable cover may be permeable to a gaseous sterilant, and the gaseous sterilant may be vaporized hydrogen peroxide or ethylene oxide.

[0009] In another aspect, the disclosure is directed to a method of removing an external sterilized syringe from a package, the package including a tray having a cavity, a deformable protrusion communicating with the cavity, and an opening covered with a gas permeable material. The method may include removing the gas permeable material to expose the opening in the tray, deforming the protrusion into the cavity and toward the barrel of the external sterilized syringe, where deforming the protrusion also bends a portion of the tray, and ejecting the external sterilized syringe from the tray.

[0010] Various embodiments of the method may include one or more of the following aspects: ejecting the external sterilized syringe from the tray may occur without the user directly handling the syringe, the gas permeable material may be permeable to vaporized hydrogen peroxide or ethylene oxide, the deformable protrusion may include a bulb shape, or the external sterilized syringe may be pre-filled with aflibercept, ranibizumab, bevacizumab, conbercept, OPT-302, RTH258 (brolocizumab), PEGylated designed ankyrin repeat protein (DARPin), or RG7716.

[0011] In another aspect, the disclosure is directed to a method of removing an external sterilized syringe from a package, the package including a tray having a cavity and an opening covered with a gas permeable material. The method may include removing the gas permeable material to expose the opening in the tray, deforming a portion of the cavity toward the barrel of the external sterilized syringe such that a portion of the tray flexes, and expelling the external sterilized syringe from the tray.

[0012] Various embodiments of the method may include one or more of the following aspects: ejecting the external sterilized syringe from the tray may be performed without the user touching the external sterilized syringe with bare hands, the gas permeable material may be permeable to one or more of vaporized hydrogen peroxide or ethylene oxide, or the external sterilized syringe may be pre-filled with aflibercept, ranibizumab, bevacizumab, conbercept, OPT-302, RTH258 (brolocizumab), PEGylated engineered ankyrin repeat protein (DARPin), or RG7716.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] As used herein, the terms "comprises," "comprising," "includes," "including," or any other variation thereof, are intended to include a non-exclusive inclusion such that a process, method, article, or apparatus containing a list of elements may include not only those elements, but other elements not expressly listed or inherent to those processes, methods, articles, or apparatus. The term "exemplary" is used in the sense of "example" rather than "ideal." Additionally, the terms "first," "second," etc. are used herein to distinguish one element or structure from another, rather than to denote any order, quantity, or importance. Additionally, the terms "(a)" and "(an)" are used herein to denote the presence of one or more of the referenced item, rather than to denote a limitation of quantity.

[0017] The term "distal end", or any variation thereof, refers to the portion of the device that is furthest from the operator of the device during an injection operation. For example, the distal end of a syringe would be the needle end of the syringe. Conversely, the term "proximal end", or any variation thereof, refers to the portion of the device that is closest to the operator of the device during an injection operation. For example, the proximal end of a syringe would be the plunger end of the syringe. Additionally, as used herein, the terms "about", "substantially", and "nearly" generally mean + / - 10% of the indicated value.

[0018] As used in this disclosure, the term "sterilization" refers to achieving an appropriate level of sterility in a formulated drug substance or drug product for commercial distribution and use. Such a level of sterility may be defined in regulatory guidelines or regulations, such as, for example, guidelines issued by the US Food and Drug Administration. In some embodiments, such a level of sterility may include, for example, a 6-log reduction of the microbial population of a biological indicator disposed on the exterior or interior surface of a pharmaceutical product (e.g., the exterior surface of a syringe or the interior surface of a blister pack). In other embodiments, such a level of sterility may include, for example, a 9-log or 12-log reduction of the microbial population of a biological indicator. Sterilization refers to achieving such an appropriate level of sterility while also achieving sufficiently low levels of residual sterilizing chemicals (e.g., vaporized hydrogen peroxide, ethylene oxide, etc.) for commercial distribution and use. Such low levels of residual sterilizing chemicals may also be defined in regulatory guidelines or regulations.

[0019] As used in this disclosure, the term "external sterilization" refers to sterilization of a drug delivery device in a container or package, such as in a primary packaging component, or in both primary and secondary packaging components, suitable for commercial distribution and use.

[0020] Embodiments of the present disclosure relate to packaging for medical devices, particularly packaging for syringes (e.g., pre-filled syringes). In some embodiments, the packaging may be configured to accommodate an externally sterilized syringe. In particular, embodiments of the present disclosure relate to packaging for an externally sterilized, pre-filled syringe containing an ophthalmic agent. An exemplary ophthalmic syringe may be pre-filled with, for example, 50 mL or less, 20 mL or less, 15 mL or less, 10 mL or less, 5 mL or less, or 1 ml or less of an ophthalmic agent. In some embodiments, the exemplary packaging may have a nominal size of less than 1 mL. An exemplary syringe is described in International Application No. PCT / US2020 / 036200, which is incorporated herein by reference in its entirety. The packaging may include one or more features to facilitate removal of the medical device from the packaging. For example, the packaging may include one or more deformable protruding portions that may be inverted, pushed, and / or otherwise deformed to remove, eject, push, or otherwise move the medical device to release it from the packaging. The packaging may also be flexible to allow a user to press protrusions to bend or flex the packaging to facilitate release of the medical device contained therein.

[0021] In some exemplary embodiments, the deformable portion may include a protrusion, such as a dome mound, or other bulbous protrusion, connected to a base of the packaging where the medical device, such as a syringe, is configured to be positioned when the medical device is contained within the packaging. The protrusion may extend outward from where the medical device is configured to be located and may be accessible from an exterior surface of the packaging.

[0022] To facilitate removal of the medical device from the packaging, the user may orient the packaging so that the opening of the packaging is angled toward the surface onto which the medical device is to be ejected. The user may also push the protrusion to bend the packaging so that one or more edges of the packaging bend away from the medical device while the central portion of the packaging bends toward the medical device. For example, the user may push the protrusion while bending the packaging to turn the packaging sideways or upside down to eject a syringe from a tray onto a sterile surface, e.g., a sterile table, tray, cloth, liner, etc. The bending of the packaging while the opening of the packaging is angled gravitationally downward allows the medical device to be released, e.g., ejected, from the packaging onto a surface with the user only touching the packaging and not directly touching the medical device.

[0023] Pressing the protrusion may also at least partially invert the protrusion. The inverted portion of the protrusion may or may not contact the medical device contained within the packaging to aid in pushing the medical device out of the packaging. In some embodiments, pressing the protrusion to bend the packaging may be sufficient to eject the device, while in other embodiments, the inverted protrusion may push a portion of the medical device (e.g., the barrel of a syringe) to facilitate ejection of the device from the packaging. In effect, the protrusion may act as a central landmark or target for the user to press to bend the packaging and eject the device. The protrusion may include, for example, an arrow or other visual indicator to indicate to the user to press the packaging in a central location to bend the packaging and eject the syringe. Exemplary aspects of the packaging are described in further detail herein.

[0024] 1 shows a bottom view of an exemplary packaging 100 for a medical device. In particular, the packaging 100 may be designed to accommodate a drug delivery device such as a syringe, e.g., a pre-filled syringe. The exemplary pre-filled syringe may be used for any therapy of ocular diseases, including for the treatment of patients with wet Age-related Macular Degeneration (AMD), macular edema following Retinal Vein Occlusion (RVO), Diabetic Macular Edema (DME), and / or Diabetic Retinopathy (DR). In particular, PEGylated engineered ankyrin repeat proteins (DARPins) such as aflibercept (Eylea®), ranibizumab (Lucentis®), bevacizumab (Avastin®), conbercept, OPT-302, RTH258 (brolucizumab), abicipar pegol, or large and small molecule antagonists of VEGF and / or ANG-2 such as RG7716 may be used in the exemplary syringes. The embodiments of the present disclosure may also be used in cosmetic applications or medical dermatology, such as treating or diagnosing allergic reactions. The package 100 includes a tray 8 in which the syringe is housed during storage and a lip 9 that extends around the tray 8 and defines an opening in the tray 8. The top of the tray 8 (shown in FIG. 4) may be sealed with a removable cover 28 (FIG. 3A), which allows the syringe to be enclosed within the tray 8 during sterilization and storage or during sterilization or storage. In some embodiments, the package 100 may be a blister package, i.e., the package 100 may be a preformed plastic package, and the tray 8 may be made from a moldable web, such as thermoformed plastic.

[0025] The package 100 may be suitable for use in an external sterilization process, such as a vapor hydrogen peroxide (VHP) sterilization process and / or an ethyl alcohol sterilization process. Thus, a medical device (e.g., a pre-filled syringe) can be packaged in the package 100 and then subjected to external sterilization. A sterilant such as VHP can sterilize the exterior of the syringe without affecting the medication contained within the syringe. An exemplary sterilization process is described in International Application No. PCT / US2018 / 021013, which is incorporated by reference in its entirety. The material used in the package 100 may be semi-permeable to the sterilant, allowing the sterilant to traverse some or all of the package 100 and sterilize the exterior of the medical device contained within the package 100 and the interior of the package 100 once the medical device is sealed within the package 100. For example, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95% of the package 100 is sterilized. For example, removable cover 28 (FIG. 3A) may be permeable to vaporized hydrogen peroxide and / or ethyl alcohol. Cover 28 may be formed, for example, of Tyvek or other suitable high density polyethylene fibers, ethylene-vinyl acetate, and / or other thermoplastic materials. In some embodiments, tray 8 may include an indicator to allow a user to determine whether tray 8 and its contents have been sterilized. For example, tray 8 may include an indicator (e.g., tape or label) that changes color or pattern appearance to visually indicate whether the sterilization process has occurred.

[0026] As described herein, by designing the package 100 to be used in an external sterilization process and to allow the user to remove the contents of the package 100 without directly handling the contents, the likelihood of compromising the sterility of the contained medical device is reduced. As a result, as described herein, the package 100 can also reduce the likelihood of the medical device infecting a person in whom the medical device is used. For example, if the package 100 contains an ophthalmic syringe, the package 100 can reduce the risk of a person contracting an eye infection, e.g., an intraocular infection such as post-injection endophthalmitis, as a result of a contaminated syringe.

[0027] An externally sterilized syringe may be one in which viable organisms on the surface of the syringe have been destroyed or killed, rendering them non-viable if they might have remained. The exterior surface of the syringe plunger rod, the flange, the rear surface of the piston, and the interior of the syringe barrel behind the syringe piston, as well as any other exterior surfaces of the syringe, may be externally sterilized. In some aspects, depyrogenation and / or other removal processes may be performed prior to external sterilization.

[0028] The tray 8 may include a cavity 3 configured to accommodate a distal portion of a syringe. The distal end of the syringe may include, for example, a luer lock and / or a syringe attachment to which a needle may be attached once the syringe is removed from the tray 8 for use. In other embodiments, the needle may already be attached to the syringe in the package 100 and may be further covered with a cap during storage in the package 100. The cavity 2 may be configured to accommodate at least a portion of a syringe barrel (which may be a glass or plastic material compatible with a sterilant), and the cavity 5 may be configured to include a flange and / or a plunger of the syringe. The cavity 5 may be shaped to correspond to the shape of the flange and / or the plunger of the syringe, as shown in FIG. 1. For example, the flange portion 6 of the cavity 5 may correspond to the shape of the flange. Comparing FIG. 1, FIG. 5, and FIG. 7, the shape and / or sidewall of the flange portion 6 of the cavity 5 may be rounded to accommodate the flange of the syringe. 2, 6 and 8, the interior region of flange portion 6 of cavity 5 may be configured to include, for example, rounded side walls to accommodate the flange of a syringe.

[0029] In some aspects, the syringe housed within the tray 8 may include a larger, e.g., wider, plunger rod, or a larger portion of the plunger rod, as compared to a standard syringe, to increase the stability of the clinician's hand when depressing the plunger rod, for example, for intravitreal injections (FIGS. 7 and 8). In such aspects, the package 100 may be sized and shaped to accommodate the larger plunger rod. If the syringe housed within the tray 8 includes a protective plunger stop, cover, and / or other element to prevent movement of the syringe plunger and / or dispensing of the medication within the syringe, the cavity 5 may be shaped to reflect the contours of the flange and / or plunger with the protective element in place. However, in other embodiments, the cavity 5 may be substantially rectangular, oval, or any other suitable shape, so long as the interior region of the cavity 5 defines a space large enough to accommodate the proximal portion of the syringe and any associated protective elements, if included. For example, Figures 5 and 6 show an exemplary embodiment where the longitudinal sidewalls of the cavity 5 are generally planar and parallel to at least a portion of the plunger rod of the syringe. Figures 7 and 8 show an exemplary embodiment where the cavity 5 may include a recessed portion 11 shaped to correspond to the shape of at least a portion of the flange or plunger, for example, the shape of a protective plunger stop, cover, and / or other element to prevent the movement of the syringe plunger and / or the distribution of the medicament in the syringe. For example, the recessed portion 11 may be between the main area of ​​the cavity 5 and the flange portion 6. In an exemplary embodiment, for example, in Figure 5, the shape of the cavity 5 may be sized to facilitate high speed manufacturing of the package 100 and improve material distribution of the package 100, or to facilitate high speed manufacturing of the package 100 or improve material distribution of the package 100.

[0030] Similarly, while in the exemplary embodiment of FIG. 1, cavity 3 is shown as substantially rectangular and cavity 2 is shown as generally square, cavity 3 and cavity 2 may each be any suitable size and shape or shape to accommodate the distal end of the syringe (and any cover that may be contiguous with the distal end) and at least a portion of the syringe barrel. For example, cavities 2 and 3 may be oval, circular, trapezoidal, or wider or narrower rectangular, or any combination thereof. Cavities 2, 3, and 5 may be dimensioned to provide space between the walls of the cavity and the syringe to allow sterilant to circulate within package 100 during the sterilization process to sterilize the inner surface of package 100 and the outer surface of the syringe. Additionally, tray 8 and cavities 2, 3, and 5 may have substantially flat surfaces on the top and bottom (e.g., cover 28 and base) to allow multiple packages to be stacked on top of each other during storage. Flat surfaces may also allow for consistent placement within an autoclave. Although, in some embodiments, cavity 2, cavity 3, cavity 5 and tray 8 may have rounded, e.g., cylindrical, or any other suitable shape. Additionally, tray 8 may have rounded or sharp corners and edges or corners or edges. In an exemplary embodiment, for example, with reference to FIG. 5 , the shape and size or shapes or sizes of cavity 2, cavity 3, cavity 5 and tray 8 may be shaped and sized or shaped or sized to facilitate high speed production of package 100 and improve material distribution of package 100 or to facilitate high speed production of package 100 or improve material distribution of package 100.

[0031] In the embodiment of Figures 1, 5 and 7, narrowed portion 7 extends between cavity 2 and cavity 3 and cavity 5, fluidly connecting all three cavities. Narrowed portions 7 are sized to accommodate regions of the syringe barrel therein, allowing the syringe to extend into all three cavities when contained within package 100, as can be seen in Figures 2, 6 and 8. For example, in Figures 2, 6 and 8, the plunger flange 14 of the packaged syringe is within flange portion 6 of cavity 5, the syringe barrel 12 extends within narrowed portion 7 and across cavity 2, and the distal region of the syringe, at least partially covered by guard 15 (e.g., a luer lock), is within cavity 3, as previously described.

[0032] Although the tray 8 is shown as including three cavities 2, 3, 5 extending along a longitudinal axis 22 (FIGS. 2, 6, and 8) and connected to one another by a narrowed portion 7, it is contemplated that the tray 8 may have any suitable number of cavities. For example, one cavity of substantially equal depth may be included to hold a medical device, two cavities may be included, or more than three cavities may be included. The cavities (in embodiments having multiple cavities) may be connected to one another such that they can combine to house a medical device. Alternatively, if multiple medical devices or multiple components are housed in the tray 8, the tray 8 may include multiple cavities that are not connected to one another. In such an embodiment, it is contemplated that two or more of the cavities may include protrusions to facilitate removal of the medical devices and / or components from the tray 8, as described further below.

[0033] In the embodiment of Figures 1 and 2, the cavity 2 includes a dome 4 at the bottom of the package 100. The dome 4 may be a flexible hollow protrusion in the tray 8 configured to facilitate removal of the syringe from the package 100. The dome 4 is connected to the base of the cavity 2 such that the dome 4 is oriented below the syringe when the syringe is contained within the package 100. In the embodiment of Figure 2, the dome 4 is aligned with the central region of the syringe barrel 12. The dome 4 may be made of a compressible material that deforms under pressure, e.g., pressure applied by a user. The dome 4 may be made of the same material as the rest of the tray 8, or may be made of a different, e.g., relatively highly flexible, material. In some embodiments, as described above, the dome 4 and the tray 8 may be thermoformed plastic. For example, the dome 4 and / or the tray 8 may be formed of polypropylene, polystyrene, polyethylene, polycarbonate, polyvinyl chloride, or polyethylene terephthalate glycol (PETG). The diameter of the base of the dome 4 (e.g., the widest part of the dome 4 where it meets the base of the tray 8) may be about 10 mm to 20 mm, e.g., about 10 mm, about 11 mm, about 12 mm, about 13 mm, about 14, about 15 mm, about 16 mm, about 17 mm, about 18 mm, or about 19 mm. With reference to Figure 5, as compared to Figure 1, the diameter of the base of the dome 4 may be sized to facilitate high speed production of the package 100 and improve material distribution in the package 100, or to facilitate high speed production of the package 100 or improve material distribution in the package 100.

[0034] FIG. 3A shows a cross-sectional view of a tray 8 containing a syringe (e.g., an empty or pre-filled syringe containing an ophthalmic medication). As described above, the dome 4 projects outwardly from the base of the tray 8 away from the syringe when the syringe is received in the tray 8, and the dome 4 is aligned with the syringe barrel 12 below (or above, depending on the orientation of the tray 8). To remove the syringe from the package 100, the removable cover 28 may be removed, e.g., peeled off, the tray 8 may be turned on its side or upside down to position the opening of the package facing a surface, and the dome 4 may be pressed by a user. The user may press the dome 4 with one or more fingers (e.g., thumb) toward the syringe contained within the package. When the user presses the dome 4, the package may bend such that one or more edges of the package bend away from the medical device while a central portion of the package bends toward the medical device. When the packaging 100 is flexed (FIG. 3B), this allows the syringe to be removed from the packaging. Because the packaging 100 is oriented with the opening gravitationally facing downwards (or at least perpendicular to the surface below), the syringe can be expelled from the packaging 100 onto the surface. Thus, by pushing the dome 4 to flex the packaging 100, the user can remove the syringe from the packaging 100 without ever directly touching the syringe. If the packaging 100 is held upside down, the syringe will not fall out on its own, and the packaging 100 can hold the syringe suspended until the user flexes the packaging 100, for example by pushing the dome 4.

[0035] When a user pushes on the dome 4 to bend the tray 8, the dome 4 may deform and at least partially invert. The dome 4 may or may not be configured to contact the syringe barrel 12 when inverted. In some embodiments, the dome 4 may push on the syringe barrel 12 to assist in moving the syringe out of the package 100. In such embodiments, the height of the dome 4 from the apex of the dome 4 to the base of the cavity through which the dome 4 extends may be greater than the distance from the base of the cavity to where the medical device (e.g., a syringe) is positioned within the tray 8. As used herein, the term "apex" refers to the portion of the dome 4 that is furthest from the base of the cavity through which the dome 4 extends, regardless of the relative orientation of the dome 4 and the tray 8. In an exemplary embodiment, the syringe may be accommodated within the tray 8 such that the height of the dome 4 from the apex of the dome 4 to the base of the tray 8 is about 5 mm to 6 mm, provided that the distance between the base of the tray 8 and the bottom of the syringe covering the dome 4 is about 3 mm to 4 mm. However, in other embodiments, the dome 4 may not contact the syringe barrel 12 when pressed by a user. Instead, the deflection of the tray 8 caused by pressing the dome 4, combined with the gravitational downward orientation of the opening of the tray 8, may be sufficient to dislodge the syringe from the tray 8 and cause the syringe to expel onto a surface (preferably a sterile surface).

[0036] A user can push the dome 4 to bend the tray 8 (i.e., reorient the tray 8 so that the opening faces gravitationally downward) before, during, and / or after orienting the tray 8 such that the opening of the tray 8 faces downward or sideways toward the surface onto which the syringe is to be discharged. Orienting the tray with the opening facing the surface allows the syringe to be dropped from the tray 8 onto a suitable sterile surface without the user having to directly handle the syringe to remove it from the packaging. Reducing the amount of handling of the syringe by the user may reduce the likelihood that the syringe and / or its contents may become contaminated and infect the part of the body into which the contents of the syringe are injected. For example, a sterile ophthalmic syringe may be contained within the packaging 100, and the dome 4 and packaging 100 may ensure that sterility is not compromised by the user when removing the syringe, which may ultimately reduce the risk of eye infections, such as post-injection endophthalmitis, due to a contaminated syringe. Reducing handling of the syringe may also reduce the risk of accidentally expelling some of the medication from the syringe when the syringe is removed from the package 100.

[0037] The location of the dome 4 protrusion and / or other protruding portions on the tray 8 can facilitate removal of the syringe as well as guide the user on how to handle certain portions of the package 100 when removing the syringe from the package 100. For example, in some embodiments, the dome 4 or other portions of the package 100 may include markings, indicia, and / or tactile features (e.g., ridges, bumps, or grooves) that indicate to the user where to press to flex the tray 8 and release the syringe from the package 100. Overall, the inclusion of the dome 4 or other suitable protrusions on the tray 8 can reduce one or more of the following possibilities: injury to the user, damage to the device, loss of sterility of the device or any agent within the device, and / or accidental release of an agent within the device.

[0038] In some embodiments, the syringe may be released from the friction fit portion of the tray 8 by pushing the dome 4 and / or bending or flexing the tray 8. For example, as shown in FIG. 4, the narrowed portion 7 may include one or more geometric features 17 that protrude into the narrowed portion to hold the sterile syringe in the cavity by friction fit. The geometric features 17 may be located on the sidewalls of the narrowed portion 7 and / or on the bottom of the narrowed portion 7 to position the syringe barrel 12 within the narrowed portion 7. The syringe may be packaged within the tray 8 such that the package 100 both facilitates sterilization, e.g., to reduce the contact area with the syringe and maximize the surface area of ​​the syringe available for sterilization while still retaining and suspending the syringe within the tray 8 when turned upside down, the syringe may be pushed into the tray 8 such that the syringe barrel 12 slides past the geometric features 17 and the syringe friction fits within the tray 8. When the syringe barrel 12 is pressed into place within the tray 8, the geometric feature 17 may keep the syringe barrel 12 within the narrowed portion 7 and retain the syringe within the tray 8. To release the syringe from the tray 8, pushing on the dome 4 may cause the tray 8 to bend and / or push the syringe barrel 12 up so that it moves past the geometric feature 17. For example, bending the tray 8 may force the portion of the tray 8 containing the geometric feature 17 away from the syringe, thereby releasing the syringe. Thus, the dome 4 may be used in combination with other friction fit portions of the tray 8 to facilitate release of the syringe from the tray 8.

[0039] One or more geometric features 17 located at the base of narrowed portion 7 may act in conjunction with geometric features 17 on the side walls of narrowed portion 7 to orient the syringe such that it does not directly contact the side walls of narrowed portion 7 and any of the other cavities (e.g., cavity 2, cavity 3, cavity 5 when contained within package 100). This may allow sterilant within package 100 to circulate within package 100 and around the exterior surface of the syringe. By including geometric features 17 to hold the syringe in place and away from the interior surface of the package, geometric features 17 may reduce the surface area of ​​the syringe that contacts the interior walls of package 100, thereby increasing the surface area of ​​the syringe that is exposed to the sterilant within package 100.

[0040] 4, it is contemplated that each narrowed portion 7 may include a fewer number (e.g., two) or more than three geometric features 17. Additionally, geometric features 17 may be included in any suitable portion of tray 8, including any combination of cavities, in place of or in addition to a narrower portion such as narrowed portion 7.

[0041] Although reference is made herein to a dome-shaped portion, it should be understood by one of ordinary skill in the art that the protrusion on the tray 8 may have any suitable shape, provided that it can be pushed to bend the tray 8 and / or compress into an inverted position. Additionally, while the tray 8 is depicted as including three cavities 2, 3, and 5 connected to one another by a narrowed portion 7, it is contemplated that the tray 8 may have any suitable shape with one or more cavities for housing a medical device. For example, while the embodiments of the present disclosure concern packaging for syringes, e.g., pre-filled syringes, it should be understood that the protrusions, such as the domes 4, may be used in combination with packaging for any suitable medical device and / or consumer goods. Thus, the tray 8 may be shaped to house other types of medical devices. Additionally, multiple protrusions, e.g., multiple domes 4, may be incorporated into the tray 8 to facilitate removal of the medical device therein.

[0042] As discussed above, the use of dome 4 on a package (e.g., a blister package) to release a syringe contained within the package may reduce the amount of direct contact a user needs to have with the syringe before administering the contents of the syringe to a person, thereby increasing sterility, dose accuracy, and / or safety of the syringe and the user, which in turn may reduce the risk of accidentally expelling the contents of the syringe before administering the medication to a person, and may reduce the incidence of infection in a person.

[0043] 1 and 2, the package 100 may also include a lip 9 that extends around at least a portion of the tray 8 to define an opening for the tray 8. The lip 9 may allow a removable (e.g., peelable) cover 28 to be sealed over the top opening of the tray 8 to accommodate the medical device within the tray 8 during storage. An adhesive 18, e.g., glue, paste, film, tape, pressure sensitive material, and / or cold adhesive, may be used to seal the removable cover 28 to the lip 9. The adhesive 18 may be compatible for use with the type of external sterilization that may be performed on the package 100. The width of the adhesive 18 may vary depending on the size of the top opening of the tray 8, e.g., increasing the size of the top opening of the tray 8 reduces the width of the adhesive 18. A corner of the lip 9, e.g., corner 16 in FIG. 2, may be free of adhesive 18, allowing a user to lift the removable cover 28 from the corner 16 to remove the cover from the tray 8. As shown in Figures 6 and 8, corner 16 may include a tab 20 (or other protrusion or indentation) that allows a user to lift removable cover 28 from corner 16 to remove cover 28 from tray 8. Tab 20 may be included on corner 16 of lip 9 or removable cover 28. In an exemplary embodiment, with reference to Figures 2 and 6, the type, shape, and / or size of lip 9 or tab 20 (or other protrusion or indentation) may be configured to facilitate high speed manufacturing of package 100 and / or improve material distribution of package 100. Removable cover 28 may be made of any suitable material, e.g., foil paper, plastic, etc., and may be permeable to a suitable gaseous sterilant, such as vaporized hydrogen peroxide or ethyl alcohol.

[0044] During use, a user may first remove the removable cover 28 from the tray 8 (e.g., by peeling the cover 28 from the lip 9) to expose the opening of the tray 8. The user may then orient the opening of the tray 8 sideways or upside down so that the opening faces the surface onto which the medical device (e.g., a pre-filled ophthalmic syringe) is to be ejected. Subsequently or simultaneously, the user may press the dome 4 (or other protruding portion), which may cause the tray 8 to bend such that one or more edges of the package bend away from the medical device while a central portion of the package bends towards the medical device. Pressing the dome 4 may cause the dome 4 to at least partially invert. In some embodiments, the inverted portion of the dome 4 may contact the medical device (e.g., the syringe barrel 12), while in other embodiments, the dome 4 may never contact the syringe. Thus, by pressing the dome 4 to bend the tray 8, the medical device may be ejected from the tray 8 such that it lands on the surface towards which the opening of the tray 8 was oriented. Suitable sterile surfaces may include, for example, a sterile table, a tray for holding medical instruments, a cloth, a liner, or any other suitable sterile surface. A combination of pressing dome 4, inverting dome 4, bending tray 8, and / or turning tray 8 on its side or upside down so that the base of tray 8 is oriented above the syringe and above the sterile surface allows the user to remove the syringe without actually touching it directly.

[0045] In some embodiments, pushing on the dome 4 may cause the tray 8 to bend, thereby releasing the medical device from a friction-fit portion of the tray 8, e.g., one or more geometric features 17. Once the syringe is released from the tray 8 (e.g., via flipping and / or bending of the dome 4), the tray 8 may be reoriented to allow the syringe to fall off the tray 8. In embodiments including multiple domes 4 (or multiple other protrusions), multiple domes 4 may be pushed to release the medical device from the tray 8 and bend different portions of the tray 8, or to either release the medical device from the tray 8 or bend different portions of the tray 8.

[0046] In the case of packaging of pre-filled syringes, any additional packaging on the syringe (e.g., a distal guard or luer lock and / or plunger guard) may be removed from the syringe once the syringe is released from the tray 8. In some embodiments, the syringe may be contained in the packaging 100 without a needle, and a needle, e.g., a stake needle, may be attached to the distal end of the syringe, e.g., via a needle attachment. The contents of the syringe (e.g., aflibercept (Eylea®), ranibizumab (Lucentis®), bevacizumab (Avastin®), conbercept, OPT-302, RTH258 (brolucizumab), a PEGylated engineered ankyrin repeat protein (DARPin) such as abicipar pegol, or a large and / or small molecule antagonist of VEGF, such as RG7716, and / or ANG-2) may then be injected into the subject's eye.

[0047] As previously discussed, the components of package 100, and the size and / or shape of such components, may be configured to facilitate rapid manufacturing of package 100 and / or to improve material distribution of package 100. Figure 9 is an exemplary embodiment illustrating a portion of the manufacturing process for package 100, in which packages 101a, 101b, and 101c are sealed with material 30 to form removable cover 28 (Figure 3), which may be, for example, Tyvek or other suitable high density polyethylene fiber, ethylene vinyl acetate, and / or other thermoplastic material.
