Abstract

A container includes an inner bag, where the interior of the inner bag includes a sterile environment for storing a material, at least one access port configured to provide fluid access to the interior of the inner bag, an overwrap bag, where the interior of the overwrap bag includes a sterile environment for storing the material and where the inner bag is enclosed within the interior of the overwrap bag, and an overwrap access port configured to provide fluid access to the interior of the overwrap bag. The material can include a biomaterial. Each of the inner bag, the overwrap bag, the at least one access port, and the overwrap access port can include a fluoropolymer such as fluoroethylenepropylene (FEP).

First claim

What is claimed is:

1. A container comprising:
an inner bag, wherein the interior of the inner bag comprises a sterile environment for storing a material;
at least one access port configured to provide fluid access to the interior of the inner bag;
an overwrap bag, wherein the interior of the overwrap bag comprises a sterile environment for storing the material and wherein the inner bag is enclosed within the interior of the overwrap bag; and
an overwrap access port configured to provide fluid access to the interior of the overwrap bag.

2. The container of claim 1 , wherein the material comprises a biomaterial.

3. A method of preserving a material, wherein the material comprises a biomaterial, the method comprising:
storing the material in a container, wherein the container comprises: an inner bag, wherein the interior of the inner bag comprises a sterile environment for storing the material; at least one access port configured to provide fluid access to the interior of the inner bag; an overwrap bag, wherein the interior of the overwrap bag comprises a sterile environment for storing the material and wherein the inner bag is enclosed within the interior of the overwrap bag; and an overwrap access port configured to provide fluid access to the interior of the overwrap bag.

4. The container of claim 1 , wherein at least one of the inner bag, the overwrap bag, the at least one access port, and the overwrap access port comprises fluoroethylenepropylene (FEP).

5. The container of claim 1 , wherein at least one of the first access port and the overwrap access port comprises a spike port.

6. The container of claim 1 , wherein at least one of the first access port and the overwrap access port comprises a luer valve.

7. A container for cryopreserving a material in a sterile, closed environment, wherein the material comprises a biomaterial, and wherein the container comprises:
an inner bag, wherein the interior of the inner bag comprises a sterile, closed environment for storing the material;
a spike port configured to provide fluid access to the interior of the inner bag;
an inlet tube configured to provide fluid access to the interior of the inner bag;
an overwrap bag, wherein the interior of the overwrap bag comprises a sterile, closed environment for storing the material and wherein the inner bag is enclosed within the interior of the overwrap bag; and
an overwrap access port comprising a spike port configured to provide fluid access to the interior of the overwrap bag;
wherein each of the inner bag, the overwrap bag, the spike port, and the overwrap access port comprise fluoroethylenepropylene (FEP).

8. The container of claim 1 , wherein the at least one access port comprises an inlet tube configured to transport the material into the inner bag in a sterile manner.

9. The container of claim 1 , wherein the inner bag comprises a cover configured to expose the at least one access port.

10. The container of claim 1 , wherein the overwrap bag comprises a secondary cover configured to expose the overwrap access port.

11. The container of claim 1 , wherein the overwrap bag is configured to store a leak of the material from the interior of the inner bag.

12. The method of claim 3 , wherein storing the material in the container further comprises:
connecting an external source to the at least one access port of the container, wherein the at least one access port comprises an inlet tube;
transporting the material in a sterile manner from the external source to the interior of the inner bag using the inlet tube;
closing the inlet tube; and
detaching the external source in a sterile manner from the inlet tube.

13. The method of claim 3 , further comprising:
accessing the material stored in the container, wherein accessing the material further comprises:
exposing at least one of the at least one access port and the overwrap access port; and
accessing the material through at least one of the at least one access port and the overwrap access port.

14. The container of claim 1 , wherein the at least one access port is at least partially enclosed within the overwrap bag.

15. The container of claim 1 , wherein the at least one access port is configured to provide sterile fluid access to the interior of the inner bag, and wherein the overwrap access port is configured to provide sterile fluid access to the interior of the overwrap bag.

16. The container of claim 1 , wherein the container comprises at least one sterile, closed environment for storing the material.
