Abstract
A catheter including a body, a vessel-fusing element coupled to the body and configured to fuse a pair of body vessels together, and a fistula-forming element positioned within and extending from the vessel-fusing element, the fistula-forming element configured to form a fistula between the pair of body vessels. Additionally two catheters with a vessel-fusing element are claimed, where one catheter also comprises a fistula-forming element.
Claims20
A catheter comprising:
- a body;
- a vessel-fusing element coupled to the body and configured to fuse a pair of body vessels together;
- and
- a fistula-forming element positioned within and extending from the vessel-fusing element, the fistula-forming element configured to form a fistula between the pair of body vessels.
A catheter system comprising:
- a first catheter comprising:
- a first body;
- a first vessel-fusing element coupled to the first body;
- a fistula-forming element coupled to and extending from the first vessel-fusing element, the fistula-forming element configured to form a fistula between a pair of body vessels;
- a second catheter comprising:
- a second body;
- and
- a second vessel-fusing element coupled to the second body and configured to fuse the pair of body vessels together between the first vessel-fusing element and the second vessel-fusing element.
A method of operating a catheter system, the method comprising:
- providing a first catheter comprising:
- a first body;
- a first vessel-fusing element coupled to the first body;
- a fistula-forming element coupled to and extending from the first vessel-fusing element, the fistula-forming element configured to form a fistula between a pair of body vessels;
- a first electrical pathway coupled to the first vessel-fusing element;
- providing a second catheter comprising:
- a second body;
- and
- a second vessel-fusing element coupled to the second body and configured to fuse the pair of body vessels together between the first vessel-fusing element and the second vessel-fusing element;
- and
- actuating a generator electrically connected to the first electrical pathway to energize the first electrical pathway.
