Abstract

A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

First claim

What is claimed is:

1. A packaged implant comprising:
an implant;
a container having a first portion and a second portion; the first and second portions being made of a non-porous material; wherein the first and second portions sealed together to form a pouch around the implant; and
a pad including a hydrogel positioned between the first and second portions within the container.

2. The packaged implant of claim 1 , wherein the implant is a prosthetic heart valve.

3. The packaged implant of claim 1 , wherein the hydrogel is glycerol and the pad is soaked with the glycerol.

4. The packaged implant of claim 1 , wherein the implant includes a quick connect system having at least one tether.

5. The packaged implant of claim 4 , wherein the quick connect system includes two tethers.

6. The packaged implant of claim 4 , wherein the first and second portions are sealed around the at least one tether and each tether at least partially extends out of the container.

7. The packaged implant of claim 6 , wherein each tether includes a fastener positioned outside of the container.

8. The packaged implant of claim 7 , wherein each fastener is configured to be connected to a prosthetic heart valve delivery device.

9. A packaged implant comprising:
an implant;
a container having a first portion and a second portion; the first and second portions being made of a non-porous material; wherein the first and second portions sealed together; and
a pad soaked with a hydrogel positioned within the container, the pad positioned on the first and second portions to surround the implant.

10. The packaged implant of claim 9 , wherein the implant is a prosthetic heart valve.

11. The packaged implant of claim 9 , wherein the hydrogel includes glycerin.

12. The packaged implant of claim 9 , further comprising a quick connect system connected to the implant, the quick connect system having at least one tether.

13. The packaged implant of claim 12 , wherein the at least one tether extends out of the container.

14. The packaged implant of claim 13 , wherein the at least one tether includes a fastener positioned outside of the container; wherein the fastener is configured to be connected to a prosthetic heart valve delivery device.

15. A packaged implant comprising:
an implant;
a quick connect system connected to the implant, the quick connect system having at least one tether;
a container having a first portion and a second portion; the first and second portions being made of a non-porous material; wherein the first and second portions are sealed together to form a pouch around the implant with the at least one tether extending out of the container; and
a hydrogel positioned within the container between the first and second portions.

16. The packaged implant of claim 15 , wherein the quick connect system includes two tethers.

17. The packaged implant of claim 15 , further comprising a pad soaked with the hydrogel.

18. The packaged implant of claim 17 , wherein the pad surrounds the implant.

19. The packaged implant of claim 15 , wherein the implant is a prosthetic heart valve.

20. The packaged implant of claim 15 , wherein the at least one tether includes a fastener positioned outside of the container; wherein the fastener is configured to be connected to a prosthetic heart valve delivery device.
