System and method for percutaneous coronary artery bypass

A method of bypassing a restriction in a native vessel of a mammal having an aorta, the method comprising:

• providing a graft having a body portion with a first end, a second end and a lumen therebetween;
• forming an aperture in the aorta;
• advancing a snare through the aperture in the aorta;
• advancing across the restriction in the native vessel a wire and forming an aperture in the native vessel with the wire distal of the restriction;.
• capturing a distal end of the wire with the snare;
• moving the distal end of the wire into the aorta with the snare;
• and
• advancing the graft over the wire between the aorta and the native vessel.

A method of bypassing a restriction in a native vessel of a mammal having an aorta, the method comprising:

• providing a graft having a body portion with a first end, a second end and a lumen therebetween;
• providing a first expandable stent at the first end of the graft;
• providing a second expandable stent at the second end of the graft;
• forming an aperture in the aorta;
• forming an aperture in the native vessel distal of the restriction;
• inserting the graft between the aperture in the aorta and the aperture in the native vessel;
• inserting at least a portion of the first stent through the aperture in the native vessel and deploying the first stent to connect the first end of the graft within the native vessel;
• positioning the second stent such that a first expandable portion is outside the aorta and a second expandable portion is within the aorta;
• and
• expanding the first and second expandable portions of the second stent- to have outer diameters at least as large as the aperture in the aorta to anchor the first end of the graft in the aorta such that the lumen in the graft communicates with the aorta and the native vessel.
