Abstract

Anastomotic components may be attached to hollow bodies or vessels by magnetic or mechanical force to create an anastomosis, form a port in a vessel, or repair a diseased vessel lumen. Anastomoses are created by coupling a first connection to an end of a vessel and then attracting it to a second connector secured to the side wall of another vessel. The connection between the first and second connectors may be solidly magnetic, solely mechanical, or a combination thereof. Also disclosed are methods and devices for treating diseased vessel lumens, for example abdominal aortic aneurysm. A plurality of docking members is attached to the vessel at solicited positions, and then one or more grafts is secured to the docking members in any suitable manner.

Claims

1. A method for forming an anastomosis between two blood vessels using magnetism, the method comprising the steps of:

securing a first component to a first blood vessel;

securing a second component to a side wall of a second blood vessel with an opening in the second component substantially aligned with an opening in the side wall of the second blood vessel;

placing the first component in contact with at least one of the second component and the side wall of the second blood vessel;

positioning an intimal surface of the first blood vessel adjacent an intimal surface of the second blood vessel; and

using magnetism to couple the first and second components and form an anastomosis between the first and second blood vessels.

2. The method of claim 1, wherein the first component is secured to an end portion of the first blood vessel and is placed in contact with the second component.

3. The method of claim 2, wherein the first and second components are coupled to form an end-to-side anastomosis between the first and second blood vessels.

4. The method of claim 3, wherein the intimal surface of the first blood vessel extends along a length of the first component and is positioned next to the intimal surface of the side wall of the second blood vessel.

5. A method for forming an anastomosis between two blood vessels, the method comprising the steps of:

securing a first component to an end of a first blood vessel, wherein the first component and the end portion of the first blood vessel have substantially the same length and an intimal surface of the first blood vessel is uncovered by the first component;

securing a second component to a side wall of a second blood vessel with an opening in the second component substantially aligned with an opening in the side wall of the second blood vessel;

placing the first component and the end portion of the first blood vessel through the opening in the second component and the opening in the side wall of the second blood vessel, wherein the uncovered intimal surface of the first blood vessel is disposed adjacent an intimal surface of the side wall of the second blood vessel; and

coupling the first and second components to form an anastomosis between the first and second blood vessels.

6. The method of claim 5, wherein the first and second components are magnetically coupled.

7. The method of claim 5, wherein the first and second components are mechanically coupled.

8. The method of claim 5, wherein the second component is sized and configured to receive the first component and the end portion of the first blood vessel so as to place respective intimal surfaces of the first and second blood vessels in close proximity to each other.

9. The method of claim 8, wherein the first component has a length that is substantially equal to the thickness of the second component combined with the thickness of the side wall of the second blood vessel.
