Description

FIELD

The present invention relates generally to packages for medical devices, and more particularly to receptacles configured to secure various medical devices of a similar or common geometry within a single receptacle for antiseptic transportation.

BACKGROUND OF THE INVENTION

As is commonly known, medical devices, such as those used for implanting or using on a patient must be sterile, undamaged, or otherwise compromised before implanting or using on the patient. Particularly, the medical devices are transporting from a manufacturer, distributor, medical-related facility, and/or area that may or may not be sterile to a facility or space that is required to be sterile. Therefore, packaging is used to transport the medical devices into a sterile atmosphere.

However, certain packaging for medical devices can be unstable or unsupportive of the device in transport, wherein the medical device moves around undesireably in the package to cause damage. This is often due to the fact medical devices are designed to be customizable to a patient and the needs of the patient. As such, one type of packaging may not be suitable or accommodating to each and every medical device to deliver the medical device undamaged and sterile. In many instances, one type of packaging is used to accommodate many devices even though they have differing sizes, shapes, and geometry which results in some of the medical devices be unsecure in the package because the devices may move around therein. Alternatively, in other instances, a package may be used for each and every varying type of medical device which can be very costly.

Additionally, an interest in ergonomic, sterile, and efficient ease of removal of the devices is becoming increasing more desired. As such a hermetically sealed type package that also allows for the contents therein to be removed and safety passed to sterile zones is desired. Furthermore, a safe and organized storage of the medical devices within the packaging is also desired.

Therefore it is desirable to have a rigid sterile medical device package that is capable of securing related or similar medical devices having common geometry within the same holder that minimizes cost in producing custom packing.

SUMMARY OF THE INVENTION

In concordance and agreement with the present invention, a rigid sterile medical device package that is capable of securing related or similar medical devices having common geometry within the same holder that minimizes cost in producing custom packing has surprisingly been discovered.

In a first embodiment of the present disclosure, a package assembly for carrying medical devices is disclosed. The package assembly includes an outer cartridge and an inner cartridge. The inner cartridge receives the outer cartridge of the package assembly. The inner cartridge extends beyond the outer cartridge. A medical device is disposed in the inner cartridge to engage the inner cartridge.

In another embodiment of the disclosure, a package assembly for carrying medical devices is disclosed. The assembly includes an outer cartridge and an inner cartridge receiving the outer cartridge. The inner cartridge extends beyond the outer cartridge. A medical device is disposed in the inner cartridge, wherein the medical device expands beyond the inner cartridge.

In yet another embodiment of the disclosure, a package assembly for carrying medical devices is disclosed. The assembly includes an outer cartridge including a cap and a main body and an inner cartridge receiving the outer cartridge. The inner cartridge extends beyond the outer cartridge. The inner cartridge includes a cap and main body and a medical device is disposed in the inner cartridge, wherein the medical device expands beyond the inner cartridge.

FIGS. 1-2 illustrate a package assembly 10 according to an embodiment of the instant disclosure. The package assembly 10 is configured for transporting a medical device 12, described herein below. The package assembly 10 includes an outer cartridge 14, an inner cartridge 16, and the device 12.

The outer cartridge 14 includes a cap 18 and a main housing 20 threading engaging each other. The cap 18 of the outer cartridge 14 includes threads 22 disposed on an internal surface thereof. The main housing 20 of the outer cartridge 14 includes threads 24 disposed on an outer surface thereof. The threads 24 of the main housing 20 engage and receive the threads 24 of the cap 18. The cap 18 and the main housing 20 cooperate with each other to define an inner chamber 26 of the outer cartridge 14. In the embodiment illustrated, the outer cartridge 14 is substantially cylindrical in shape. However, it is understood the outer cartridge 14 can have any shape as desired such as cubical, spherical, having a polygonal cross-sectional shape, having a ovular cross-sectional shape, pyramidal, or any shape or combination of shapes as desired. An outer cartridge seal 34 configured as an annular resilient seal such as an o-ring, for example, is disposed between a shoulder 36 and an end of the cap 18. It is understood, the seal 34 can be configured as a metal seal or plastic seal or any other seal as desired.

The cap 18 of the outer cartridge 14 includes a plurality of grip features 38. As shown, the grip features 38 are indentations formed in an outer surface of the cap 18. However, the grip features 38 can be ridges, a finger grip, or any other grip-type feature as desired.

The inner cartridge 16 includes a cap 58 with threads 68 formed on an inner surface thereof, and main body 62 and threads 66 formed on an outer surface thereof. The threads 68 of the cap 58 engage the threads 66 of the main body 62.

The main body 62 includes a threaded portion 41 that contains the threads 66 of the internal cartridge 16 of the main body 62 and a receiving portion 42 for receiving the medical device 12. The receiving portion 42 is a tube and has an inner diameter less than an inner diameter of the threaded portion 41. The receiving portion 42 is substantially cylindrical. However, other shapes can be employed as desired. The difference in the diameters facilitates a stable disposal of the medical device 12. An inner cartridge seal 78 configured as an annular resilient seal such as an o-ring, for example, is disposed between a shoulder 80 and an end of the cap 58. It is understood, the seal 78 can be configured as a metal seal or plastic seal or any other seal as desired.

An inner surface 44 of the threaded portion 41 of the inner cartridge 16 includes a shoulder 46 for stopping a stabilizer 48 being received through an opening of the threaded portion 41 and extending through the receiving portion 42. The stabilizer 48 is annular and has a first end 50 for receiving the medical device 12 and a second end 52 for conveying the medical device 12 threrethrough into the receiving portion 42 of the inner cartridge 16. The stabilizer 48 includes an inner aperture 54 extending therethrough with respect to a length thereof. An inner diameter of the stabilizer 48 at the first end 50 is greater than an inner diameter of the 48 stabilizer in an intermediate section 56 thereof. A cross-sectional shape of the stabilizer 48 at the first end has a frustoconical portion 72 configured to receive the medical device 12 such as a head 74 of a screw, wherein the remainder of the inner aperture 54 of the stabilizer 48 is for receiving a stem 76 of elongated part of the medical device 12. A diameter of the frustoconical portion 72 increases constantly from adjacent the intermediate section 56 to the first end 52 of the stabilizer 48. As a result, the head 74 of the medical device 12 is stabilized and supported.

As shown in FIG. 2, the main body 62 of the inner cartridge 16 extends beyond the main housing 20 of the outer cartridge 14. As shown the threads 66 of the inner cartridge 16 extend beyond the threads 24 of the outer cartridge 14 with respect to a length direction of the outer cartridge 14 in a direction towards the cap 18 of the outer cartridge 14. The threads 66 of the internal cartridge 16 extending beyond the threads 24 of the outer cartridge 14 is advantageous to grip and receive the inner cartridge 16 in a sterile setting. The stabilizer 48 extends beyond the threaded portion 41 of the inner cartridge 16 towards a cap 58 of the inner cartridge 16.

The cap 58 of the inner cartridge 16 includes a plurality of grip features 60. As shown, the grip features 60 are indentations formed in an outer surface of the cap 58. However, the grip features 60 can be ridges, a finger grip, or any other grip-type feature as desired. The threaded portions 68 of the cap 58 engage the threads 66 of the main body 62.

In application, the inner cartridge 16 is removed from the outer cartridge 14. The inner cartridge 16 remains sterile. The cap 58 of the inner cartridge 16 is removed in a sterile environment. Because the stabilizer 48 extends outwardly from the inner cartridge 16, the stabilizer can be easily removed with the medical device 12.
