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

The invention claimed is:

1. A device-fill pouch assembly (DFPA) comprising:
a pouch, a device case, and an implantable device disposed within the device case, wherein the device case and the implantable device are disposed within the pouch, wherein the pouch comprises:
a) a first sheet peelably adhered to a second sheet;
b) a first opening comprising an inlet system for use in loading the implantable device with living cells, wherein the inlet system comprises a spacer tube that extends interiorly into an inner space of the pouch between the first and second sheets;
c) a second opening comprising an outlet system for use in removing solution from the pouch; and
d) one or more transparent windows to view the implantable device within the pouch,

wherein the implantable device comprises an inlet port that extends through the spacer tube.

2. The DFPA of claim 1 , wherein the implantable device is a semi-permeable encapsulation device.

3. The DFPA of claim 1 , wherein the pouch is made of a sterilizable material or paper.

4. The DFPA of claim 1 , wherein the transparent window comprises a biaxially-oriented polyethylene terephthalate, a polyester film comprising stretched polyethylene terephthalate (PET), clear polymer film, or polyethylene.

5. The DFPA of claim 1 , wherein the first or second sheet comprises polyester, polyvinyl chloride, polyethylene, polypropylene, polyolefin, an ethylene copolymer, ethylene-vinyl acetate (EVA), ethylene-methyl acrylate (EMA), ethylene-acrylic acid (EAA), an ionomer resin, a gas-permeable polyethylene fabric, a polypropylene non-woven fabric, a water-resistant fabric, a fabric resistant to chemical, or a fabric resistant to abrasion.

6. The DFPA of claim 1 ,
a) wherein the first or second sheet comprises a sterilizable paper; or
b) wherein the first and second sheet have a thickness of 0.5 mils to 4.0 mils, or 1.5 mils to 3.0 mils, or 2 mils.

7. The DFPA of claim 1 , further comprising:
a) a thermoplastic transparent resin film that is adhered between the first and second sheet; or
b) a thermoplastic polymer film that is adhered between the first and second sheet.

8. The DFPA of claim 1 , wherein the living cells are pancreatic progenitor cells, pancreatic and duodenal homeobox 1 (PDX-1) positive pancreatic endoderm cells, pancreatic endocrine precursor cells, or immature beta cells.

9. The DFPA of claim 1 , wherein the outlet system extends outside of the pouch, and wherein the outlet system comprises a drain port that extends through the second opening to the inner space of the pouch.

10. The DFPA of claim 3 , wherein the pouch is used to sterilize the implantable device; or the pouch is used to sterilize and fill the implantable device.

11. A device-fill pouch assembly (DFPA) comprising:
a pouch, a device case, and an implantable device disposed within the device case, wherein the device case and the implantable device are disposed within the pouch, wherein the pouch comprises:
a) a first sheet peelably adhered to a second sheet;
b) a first opening comprising an inlet system for use in loading the implantable device with living cells, wherein the inlet system comprises a spacer tube that extends interiorly into an inner space of the pouch between the first and second sheets;
c) a second opening comprising an outlet system for use in removing solution from the pouch; and
d) one or more transparent windows to view the implantable device within the pouch,

wherein the implantable device comprises an inlet port that extends through the spacer tube, wherein the case comprises a base body and a cover body, and wherein the cover body is movable between a closed position where the base body and cover body are coupled to one another and open position where the implantable device can be moved into and out of the case.

12. The DFPA of claim 1 , wherein the case comprises a plurality of rigid sidewalls that define a volume for receiving the implantable device therein.

13. A device-fill pouch assembly (DFPA) comprising:
a pouch, a device case, and an implantable device disposed within the device case, wherein the device case and the implantable device are disposed within the pouch, wherein the pouch comprises:
a) a first sheet peelably adhered to a second sheet;
b) a first opening comprising an inlet system for use in loading the implantable device with living cells, wherein the inlet system comprises a spacer tube that extends interiorly into an inner space of the pouch between the first and second sheets;
c) a second opening comprising an outlet system for use in removing solution from the pouch; and
d) one or more transparent windows to view the implantable device within the pouch,

wherein the implantable device comprises an inlet port that extends through the spacer tube, wherein the case comprises a detachably connected cover body and base body, and wherein the cover body has a first attachment portion and the base body has a second attachment portion, the first and second attachment portions configured to secure the cover body to the base body when the case is in a closed position.
