System and method for percutaneous coronary artery bypass
First Claim
1. A method of percutaneously bypassing a restriction in an artery of a mammal having an aorta, the artery having an artery wall defining an artery lumen and the aorta having an aorta wall defining an aorta lumen, the method comprising:
- providing a graft defining a graft lumen and having a body portion with a first end and a second end;
forming an aperture in the aorta wall;
inserting the graft into the aorta lumen;
connecting the first end of the graft to the aorta wall about the aperture in the aorta wall;
advancing the body portion of the graft through the aperture in the aorta wall after connecting the first end of the graft to the aorta wall;
forming an aperture in the artery wall distal of the restriction; and
connecting the second end of the graft to the artery wall about the aperture therein such that the graft lumen communicates with the aorta lumen and the artery lumen.

Abstract
A percutaneous system for bypassing a restriction in a native vessel of a mammal having an aorta includes providing a graft having a body portion with a first end, a second end and a lumen therebetween. An aperture is formed in the aorta. The graft is inserted into the aorta and the first end of the graft is connected to the aorta about the aperture in the aorta. An aperture is then formed in the native vessel distal of the restriction. The second end of the graft is connected to the native vessel about the aperture therein such that the lumen in the graft communicates with the aorta and the native vessel.

12. A method of percutaneously bypassing a restriction in an artery of a mammal having an aorta, the artery having an artery wall defining an artery lumen and the aorta having an aorta wall defining an aorta lumen and comprising an inner aorta wall and an outer aorta wall, the method comprising:
-
providing a graft defining a graft lumen and having a body portion with a first end and a second end; isolating a region of the inner aorta wall from blood flow while allowing blood flow through the remainder of the aorta lumen; forming an aperture in the isolated region of the aorta wall; inserting the graft into the aorta lumen; connecting the first end of the graft to the aorta wall about the aperture in the aorta wall; advancing the body portion of the graft through the aperture in the aorta wall; forming an aperture in the artery wall distal of the restriction; and connecting the second end of the graft to the artery wall about the aperture therein such that the graft lumen communicates with the aorta lumen and the artery lumen. - View Dependent Claims (13, 14, 15)

16. A method of percutaneously bypassing a restriction in an artery of a mammal having an aorta, the artery having an artery wall defining an artery lumen and the aorta having an aorta wall defining an aorta lumen and comprising an inner aorta wall and an outer aorta wall, the method comprising:
-
providing a graft defining a graft lumen, the graft having a body portion with a first end and a second end and having a coupler connected to the first end of the body portion, the coupler having a lumen running therethrough, an insertion end and a shoulder portion of greater width than the insertion end, the lumen in the coupler communicating with the lumen in the body portion; forming an aperture in the aorta wall; inserting the graft into the aorta lumen; inserting the insertion end of the coupler into the aperture in the aorta wall such that the shoulder portion abuts an inner surface of the aorta wall proximate the aperture in the aorta wall; advancing the body portion of the graft through the aperture in the aorta wall; forming an aperture in the artery wall distal of the restriction; and connecting the second end of the graft to the artery wall about the aperture therein such that the graft lumen communicates with the aorta lumen and the artery lumen. - View Dependent Claims (17, 18, 19, 20)
