Devices for sealing a body lumen
View Patent ↗Various surgical kits are provided including a sealing cuff configured to be positioned around a body lumen and a sealant. In one embodiment, the sealing cuff can form an enclosed loop around an anastomosis and can define an interior chamber for receiving sealant therein. The sealing cuff can ensure that sealant remains in contact with the body lumen as the sealant cures and reinforces the anastomosis. Methods for sealing an anastomosis are also provided and include delivering sealant to the sealing cuff, inserting inflatable members so that they are positioned adjacent to the anastomosis, and delivering fluid to at least one of the inflatable members to expand an inner wall of the tubular organ. In certain aspects, gas and/or liquid can be delivered to an anastomosis, such as after the sealant has solidified, in order to test the effectiveness of the seal.
1. A surgical kit, comprising:
a liquid sealant configured to cure into a solidified state;
a sealing cuff having a sidewall with first and second ends removably mated to one another to form an enclosed loop, the sidewall defining an interior chamber, the sealing cuff having a plurality of openings formed therein, and the sealing cuff being configured to be disposed around a body lumen such that the interior chamber is sealed between the sidewall and the body lumen to allow the liquid sealant to be received therein and to directly contact the body lumen; and
a suture extending along an inner surface of the sealing cuff and passing through each of the plurality of openings, the suture being configured to be detached from the sealing cuff after the sealant has cured into the solidified state and thereby release the sealant in the solidified state from the sealing cuff.
2. The kit of claim 1 , wherein the sealing cuff has a passageway extending circumferentially therearound in which the suture is positioned, the plurality of openings being in communication with the passageway.
3. The kit of claim 1 , wherein the sealing cuff has a passageway extending circumferentially therearound, the suture extending through the passageway.
4. The kit of claim 3 , wherein the suture includes a first suture extending through the passageway and a second suture disposed in a criss-cross pattern on the inner surface of the sealing cuff.
5. The kit of claim 1 , wherein the sealing cuff has a plurality of protrusions formed on the inner surface of the sealing cuff, the plurality of protrusions being configured to facilitate distribution of the sealant within the interior chamber.
6. The kit of claim 1 , wherein the plurality of protrusions are spaced evenly about a circumference of the sidewall.
7. The kit of claim 1 wherein the sidewall is substantially hemi-spherical and the inner surface of the sealing cuff is substantially concave.
8. The kit of claim 1 , further comprising at least one expandable member configured to move from a compressed position to an expanded position and having a shape that substantially corresponds to a shape of the interior chamber of the sealing cuff when the at least one expandable member is in the expanded position.
9. The kit of claim 1 , wherein the sealant is selected from the group consisting of fibrin, thrombin, a hydrogel, benzocaine, cyanoacrylate, polyglycolic acid, hyaluronic acid, magnesium peroxide, hydrogen peroxide, platelet rich plasma, and combinations thereof.
10. The kit of claim 1 , wherein the sealant is configured to transition from the liquid to the solidified state after a predetermined amount of time.
11. A surgical kit, comprising:
a liquid sealant configured to cure into a solidified state;
a sealing cuff having a sidewall with first and second ends removably mated to one another to form an enclosed loop, the sidewall defining an interior chamber, the sealing cuff having a passageway extending circumferentially therearound, and the sealing cuff being configured to be disposed around a body lumen such that the interior chamber is sealed between the sidewall and the body lumen to allow the liquid sealant to be received therein and to directly contact the body lumen; and
a suture extending along an inner surface of the sealing cuff and extending through the passageway, the suture being configured to be detached from the sealing cuff after the sealant has cured into the solidified state and thereby release the sealant in the solidified state from the sealing cuff.
12. The kit of claim 11 , wherein the suture includes a first suture extending through the passageway and a second suture disposed in a criss-cross pattern on the inner surface of the sealing cuff.
13. The kit of claim 11 , wherein the sidewall is substantially hemi-spherical and an inner surface of the sealing cuff is substantially concave.
14. The kit of claim 11 , wherein the sealing cuff has a plurality of extensions configured to distribute the sealant within the interior chamber, the plurality of extensions being sized and shaped such that when the sealing cuff is disposed around a tubular body organ, the plurality of extensions contact an outer surface of the tubular body organ.
15. The kit of claim 14 , wherein the plurality of extensions are spaced evenly about a circumference of the sidewall.
