Abstract
A method of implanting a graft prosthesis in the body of a patient to bypass a segment of a blood vessel. A graft is positioned so that one end of the graft is located substantially adjacent the blood vessel at a site upstream of the segment and the other end of the graft is located substantially adjacent the blood vessel at a site downstream of the segment, wherein the positioning step includes the step of advancing the graft within the body with a medical instrument. A region of the area within the blood vessel near the upstream site is isolated from fluid communication with the rest of the area within the blood vessel. An arteriotomy is made in the sidewall of the blood vessel near the upstream site to create a communicating aperture between the upstream isolated region and the outside of the blood vessel. An anastomosis is then formed between the one end of the graft and the blood vessel near the upstream site. Moreover, a region of the area within the blood vessel near the downstream site is isolated from fluid communication with the rest of the area within the blood vessel. An arteriotomy is made in the sidewall of the blood vessel near the downstream site to create a communicating aperture between the downstream isolated region and the outside of the blood vessel. An anastomosis is then formed between the other end of the graft and the blood vessel near the downstream site.
