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 securing an anastomotic component to an end of a blood vessel, the method comprising steps of:

providing an anastomotic component including a sleeve defining a lumen;

securing an end portion of a blood vessel to the anastomotic component by passing the end portion through the lumen of the sleeve;

placing an edge of the blood vessel in substantial alignment with an edge of the anastomotic component; and

passing a fastener through the end portion of the blood vessel and into locking engagement with the sleeve, the fastener leaving an exposed intimal surface that extends substantially around the sleeve, the fastener comprising a plurality of prongs that are passed through the end portion of the blood vessel, the plurality of prongs lockingly engage a plurality of slots provided in the sleeve.

2. The method of claim 1, wherein the prongs and slots are lockable in one of a plurality of positions.

3. A method for treating a lumen defined by a hollow structure in a patient'"'"'s body, the method comprising steps of:

providing a docking member configured to be secured to tissue;

providing a prosthesis configured to be magnetically coupled to the docking member, the prosthesis having an outer surface and a lumen;

securing the docking member to a vessel in a patient'"'"'s body, the vessel having a lumen with a diseased portion;

inserting the prosthesis into the vessel lumen; and

magnetically coupling the prosthesis to the docking member to place the prosthesis outer surface in sealing engagement with the vessel lumen.

4. The method of claim 3, wherein the prosthesis comprises a stent graft.

5. A method for repairing an aneurysm using magnetism, the aneurysm being located in a patient'"'"'s body lumen, the method comprising steps of:

providing a prosthesis having an outer surface and a lumen;

locating a body lumen having an aneurysm;

placing the prosthesis in a desired position with respect to the aneurysm so that the prosthesis outer surface sealingly engages the body lumen; and

using magnetism to secure the prosthesis in the selected position, wherein a docking member is first placed adjacent the desired position and the prosthesis is secured thereto.

6. The method of claim 5, wherein the docking member and prosthesis are magnetically attracted.

7. The method of claim 5, wherein docking member and prosthesis each comprise a magnet carried by a base structure.

8. The method of claim 5, wherein the prosthesis has an expandable portion.

9. The method of claim 8, wherein the expandable portion comprises a stent graft.

10. The method of claim 8, wherein the expandable portion is delivered at least partially collapsed and then is expanded.

11. The method of claim 5, wherein the prosthesis has more than one lumen.

12. The method of claim 5, further comprising placing at least one additional prosthesis in the body lumen.

13. An anastomotic component comprising:

a sleeve having a lumen provided between first and second open sleeve ends with the second end open to receive a first vessel;

a plate extending away from the sleeve, the plate having an engagement surface to engage with a surface of another anastomotic component as secured to a second vessel and permitting communication with the sleeve lumen through the first sleeve end;

at least one of the sleeve and plate including a locking portion configured to lockingly engage another anastomotic component as secured to a second vessel; and

a fastener configured to engage the first vessel via the sleeve, wherein the fastener and sleeve have interlocking elements, wherein the fastener and sleeve are lockable in a plurality of positions.

14. The anastomotic component of claim 13, wherein the fastener has a portion for penetrating a first vessel.

15. The anastomotic component of claim 14, wherein the fastener includes a ring shaped base and at least one locking arm for penetrating a first vessel and locks to the sleeve.

16. An anastomotic component comprising:

a sleeve having a lumen provided between first and second open sleeve ends with the second end open to receive a first vessel;

a plate extending away from the sleeve, the plate having an engagement surface to engage with a surface of another anastomotic component as secured to a second vessel and permitting communication with the sleeve lumen through the first sleeve end; and

at least one of the sleeve and plate including a locking portion configured to lockingly engage another anastomotic component as secured to a second vessel, wherein at least one of the sleeve and the plate has magnetic properties.

17. The anastomotic component of claim 16, further comprising a fastener configured to engage the first vessel via the sleeve.

18. The anastomotic component of claim 17, wherein the fastener and sleeve have interlocking elements.
