Abstract

A pulmonary visceral pleura anastomosis reinforcement device may be positioned in proximity to a pulmonary pleural stabilizer or conduit to be inserted into a lung. The reinforcement device provides structural reinforcement and aids in preventing damage to the visceral pleura during insertion of a conduit or other device into the lung.

Claims

1. A system that can maintain the integrity of an opening in the visceral pleura of the lung comprising:

a conduit adapted to be deployed in the visceral pleura;

a anastomosis reinforcing device that fits around the conduit;

a fastener to secures said anastomosis reinforcing device relative to said conduit with tissue of the visceral pleura between the conduit and the anastomosis reinforcing device.

2. The system of claim 1 wherein said anastomosis reinforcing device is a circular disk.

3. The system of claim 1 wherein said anastomosis reinforcing device is comprised of a material that prevents leakage.

4. The system of claim 1 wherein said anastomosis reinforcing device includes Teflon.

5. The system of claim 1 wherein said anastomosis reinforcing device provides an acute reinforcement to prevent a leakage.

6. The system of claim 1 wherein said anastomosis reinforcing device can comprise at least one of a metal, a metal alloy, and a polymer.

7. The system of claim 1 wherein the anastomosis reinforcing device can be one of biodegradable and non-biodegradable.

8. The system of claim 1 wherein said anastomosis reinforcing device includes polyglycolic acid.

9. The system of claim 1 wherein said anastomosis reinforcing device includes an animal tissue.

10. The system of claim 1 wherein said fastener can be at least one of a suture, a staple, a ring and a tissue adhesive.

11. The system of claim 1 wherein said anastomosis reinforcing device can include a tissue growth factor.

12. The system of claim 1 wherein said fastener can be a ring made of a shape memory material.

13. The system of claim 1 wherein said fastener can be a ring made of a super elastic polymer.

14. The system of claim 1 wherein said anastomosis reinforcing device can include an agent to promote a pleurodesis reaction between parietal pleura and visceral pleura.

15. The system of claim 1 wherein an agent to promote a pleurodesis reaction between parietal pleura and visceral pleura is associated with the anastomosis reinforcing device by one of:

a. affixing the agent to a surface of the device.

b. affixing a polymeric material with the agent incorporated therein to said device;

c. incorporating the agent into a hole or channel formed into the device.

16. The system of claim 1 wherein said anastomosis reinforcing device can be one of anchor and seal said conduit in place.

17. A system that can maintain the integrity of an opening in the visceral pleura of the lung when used with a device that is implanted in the lung, the system comprising:

an anastomosis reinforcing device that fits around the device;

a fastener securing said anastomosis reinforcing device relative to said device with tissue of the visceral pleura between the conduit and the anastomosis reinforcing device.

18. The system of claim 17 wherein said fastener includes one of:

a. a suture;

b. a staple;

c. an adhesive;

d. a ring;

e. a device comprised of a shape memory material;

f. a device comprised of a super elastic material.

19. A method to reinforce an anastomosis comprising the steps of:

deploying an implant into the lung;

deploying an anastomosis reinforcing device about the implant with visceral pleural tissue between the implant and the anastomosis reinforcing device;

fastening the anastomosis reinforcing device in place.

20. The method of claim 19 including the step of:

purse-string suturing the implant in place.

21. The method of claim 19 wherein said fastening step includes one of:

a. using a suture;

b. using a staple;

c. using an adhesive;

d. using a ring;

e. using a device comprised of a shape memory material;

f. using a device comprised of a super elastic material.

22. The method of claim 19 including using said method to prevent leakage about the implant.

23. The method of claim 19 wherein said implant deploying step includes deploying a conduit into the lung through the chest wall and the visceral pleura.
