Abstract

Embodiments herein describe tools and instruments for holding, transferring, delivering, deploying an implantable device and methods and means of aseptically storing and shipping the implantable device including but not limited to a device case for protecting, housing and filling the device, a surgical sizer for preparing the implantable site, a deployer for transferring the implantable device from the device case and delivering or deploying the implantable device at the prepared implantable site.

First claim

What is claimed is:

1. An assembly comprising a case and an implantable semi-permeable self-expanding macro-encapsulation device comprising a device port for transferring cells into the device, the case comprising: a device port sealing area in communication with a device port guide, a detachably connected cover body and base body, wherein the cover body has a first latch portion and the base body has a second latch portion configured to secure the cover body to the base body when the case is in a closed position, and the cover body comprises at least two windows and the base body comprises at least two windows, and when the cover body is secured to the base body, one or more biologically active materials can flow through each window, and a first and second finger grip extending from opposite sides of the base body and a first and second projection extending from opposite sides of the cover body, wherein the first and second finger grips receive the first and second projections, respectively, when the case is in the closed position, and the device is disposed between the cover body and the base body and comprises a first major surface facing the at least two windows in the cover body and a second major surface, opposite the first major surface, facing the at least two windows in the base body.

2. The assembly of claim 1 , wherein when the case is in the closed position, a portion of the device port within the device port sealing area is accessible from outside of the case.

3. The assembly of claim 2 , wherein the semi-permeable self-expanding macro-encapsulation device further comprises therapeutic agents therein.

4. The assembly of claim 3 , wherein the therapeutic agents are living cells.

5. The assembly of claim 4 , wherein the living cells are progenitor cells differentiated from stem cells in vitro.

6. The assembly of claim 5 , wherein the progenitor cells are endoderm-lineage cells.

7. The assembly of claim 5 , wherein the progenitor cells are pancreatic progenitor cells.

8. The assembly of claim 5 , wherein the progenitor cells are PDX1-positive pancreatic endoderm cells.

9. The assembly of claim 4 , wherein the living cells are endocrine cells.

10. The assembly of claim 4 , wherein the living cells are immature beta cells.

11. The assembly of claim 5 , wherein the stem cells are selected from the group consisting of human embryonic stem cells, fetal stem cells, cord blood stem cells, induced pluripotent stem cells, reprogrammed cells, parthenote cells, gonadal germ cells, mesenchymal cells, and hematopoietic stem cells.

12. The assembly of claim 1 , wherein the cover body and base body each have two windows.

13. The assembly of claim 1 , wherein the cover body and base body each have four windows.

14. The assembly of claim 1 , wherein the cover body and base body each have six windows.

15. The assembly of claim 1 , wherein the cover body and base body each have eight windows.

16. The assembly of claim 1 , wherein the case further comprises four or more finger grips.

17. The assembly of claim 1 , wherein the case further comprises a closing or attachment system.

18. The assembly of claim 17 , wherein the attachment system is selected from the group consisting of a hinge, a latch and a snap.

19. The assembly of claim 1 , wherein the case comprises a biocompatible polymer material or a metal.

20. The assembly of claim 19 , wherein the metal comprises stainless steel, gold, platinum, titanium, niobium, nickel, nickel titanium, colbalt-chrome alloys, molybdenum or molybdenum alloys, or an alloy such as nitonol or alumina ceramic.

21. The assembly of claim 19 , wherein the biocompatible polymer material comprises polycarbonate, acrylonitrile butadiene styrene (ABS), high-density polyethylene (HDPE), polystyrene, polyether ether ketone (PEEK), polypropylene, urethane, teflon, polyethylene, polymethylmethacrylate, epoxy, silicone, or parylene.

22. The assembly of claim 19 , wherein the biocompatible polymer material or metal is autoclave-safe.

23. The assembly of claim 19 , wherein the biocompatible polymer material comprises polycarbonate.

24. The assembly of claim 1 , wherein the device port sealing area and the device port guide are recessed portions formed in an inner surface of the base body.

25. The assembly of claim 24 , wherein the base body includes first and second opposing sides having a first length and third and fourth opposing sides extending between respective ends of the first and second sides, the third and fourth sides having a second length that is less than the first length, wherein the device port guide intersects the third side of the base body.

26. The assembly of claim 2 , wherein the cover body includes a cut-out at one end thereof to provide access to the portion of the device port within the device port sealing area when the case is in the closed position.
