Summary for Patent: 6,302,897

Title:	Device for deploying medical textiles
Abstract:	A thermoformed bladder is disclosed for assisting in the application of prosthetic mesh devices. The unit is fabricated from two layers of film that have been thermoformed in one localized region and then sealed. The sealed unit has air trapped within the three dimensional portion which can be forced into the non-formed region causing the non-formed region to expand and apply force against the prosthesis to assist in deployment.

Assignee:	Ethicon, Inc. (Somerville, NJ)
Application Number:	09/443,882
Patent Claims:	1. A device for the deployment of a medical textile device between layers of tissue, the deployment device comprising a first bladder, a conduit and a second bladder, wherein the first bladder is in fluid communication with the second bladder through the conduit; and an amount of a fluid effective to deploy the medical textile device between the layers of tissue contained and sealed within the deployment device, wherein the deployment device consists essentially of a polymeric film, whereby introduction or leakage of fluid into or from the sealed deployment device is prevented. 2. The device of claim 1 wherein the second bladder has a toroidal shape. 3. The device of claim 2 wherein the second bladder is positioned in contact with a medical textile device with a core. 4. The device of claim 1 wherein the fluid is air. 5. The device of claim 1 wherein the second bladder is rectangular. 6. The device of claim 1 wherein the second bladder is in contact with a medical textile device. 7. The device of claim 1 wherein the first bladder is thermoformed. 8. A device for the deployment of a medical textile between two layers of tissue, the device having a first compartment and a second compartment in fluid communication with each other, wherein in an unstressed condition the first compartment has a three-dimensional shape for the containment of a volume of fluid effective to deploy the medical textile contained and sealed within the device and the second compartment remains in an essentially flattened condition, wherein the device consists essentially of a polymeric film and introduction or leakage of fluid into or from the sealed device is prevented. 9. The device of claim 8 wherein a portion of the device in contact with the medical textile is essentially toroidal shaped in the unstressed condition. 10. The device of claim 9 wherein the fluid is air. 11. The device of claim 9 wherein the fluid is medical saline solution. 12. The device of claim 9 wherein the fluid is sterile water. 13. The device of claim 8 wherein the fluid is trapped within the device during the device fabrication process. 14. The device of claim 8 where the device is manufactured from two layers of film sealed together. 15. The device of claim 14 wherein at least one layer of film is partially formed through the application of mechanical or thermal energy.
