Abstract

An aortic graft, and method and apparatus for repairing an abdominal aortic aneurysm includes a tubular graft which is intraluminally delivered through the aorta and secured to the aorta by the expansion and deformation of a thin-walled tubular member.

Claims

1. A method for repairing an artery in a body comprising the steps of:

(a) connecting a tube to a first expandable and deformable, tubular member having a smooth outer wall surface by disposing a first portion of the first tubular member within the tube and disposing a second portion of the first tubular member outside the tube;

(b) disposing the tube and first tubular member upon a catheter having an expandable, inflatable portion with the first tubular member disposed upon the expandable, inflatable portion;

(c) intraluminally delivering the tube, first tubular member and catheter to a portion of the artery to be repaired and disposing at least a portion of the tube within the portion of the artery to be repaired;

(d) expanding the expandable, inflatable portion of the catheter to expand and deform the first tubular member to force the second portion of the first tubular member radially outwardly into contact with the artery to secure the first tubular member and at least a portion of the tube within the portion of the artery to be repaired, whereby the tube provides a fluid passageway through the artery.

2. The method of claim 1, wherein the tube has first and second ends, the first end of the tube being connected to the first tubular member, and the second end of the tube being connected to at least one second tubular member.

3. The method of claim 2, including the steps of:

(a) disposing the first and the at least one second tubular members within an artery;

(b) expanding and deforming each tubular member with a catheter to secure each tubular member within a portion of the artery.

4. The method of claim 1, including the step of providing a biologically inert coating on the tube.

5. The method of claim 1, including the step of utilizing a tube made of a material which is impervious to fluid.

6. The method of claim 1, including the step of utilizing a tube made of a material which is bioerodable.

7. The method of claim 1, wherein the tube, first tubular member, and catheter are intraluminally delivered through a femoral artery.

8. The method of claim 1, wherein the tube, first tubular member, and catheter are intraluminally delivered through an axillary artery.

9. The method of claim 1, including the step of crimping the tube to form an undulating, longitudinal cross-sectional configuration to minimize kinking or twisting of the tube.
