Abstract
Abstract A method of implanting a graft in a patient's body is disclosed. According to the method, a first end of the graft is anastomosed to the blood vessel at a first location which is covered by a substantially intact portion of the epidermis of the body, and a second end of the graft is anastomosed to the blood vessel at a second location which is visually exposed through a gaping surgical incision. The first end of the graft includes a flanged end portion which is guided into the blood vessel through an arteriotomy defined therein near the first location so as to be positioned substantially adjacent a portion of a sidewall of the blood vessel which substantially surrounds the arteriotomy. An expandable stent is then placed within the blood vessel and in contact with the flanged end portion so as to secure the flanged end portion of the graft between the sidewall of the blood vessel and the stent thereby securing the graft to the blood vessel. The graft is further secured to the blood vessel by suturing the flanged end portion and the stent to the sidewall of the blood vessel. The second end of the graft is secured to the blood vessel at the second location by standard surgical techniques.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
376 words
A method of implanting a graft prosthesis in the body of a patient to bypass a segment of a blood vessel, comprising the steps of: making an incision in the body; positioning a graft so that one end of the graft is located substantially adjacent the blood vessel at a site upstream of the segment and a second 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 placing the graft into the body through the incision, and further wherein the positioning step is performed while the upstream site is covered by a substantially intact portion of the epidermis of the body; isolating a region of the area within the blood vessel substantially adjacent the upstream site from fluid communication with the rest of the area within the blood vessel, wherein the upstream isolating step is performed while the upstream site is covered by the substantially intact portion of the epidermis of the body; making an arteriotomy in a sidewall of the blood vessel substantially adjacent the upstream site to create a communicating aperture between the upstream isolated region and an area outside of the blood vessel, wherein the upstream arteriotomy making step is performed while the upstream site is covered by the substantially intact portion of the epidermis of the body; forming an anastomosis between the one end of the graft and the blood vessel substantially adjacent the upstream site, wherein the upstream anastomosis forming step is performed while the upstream site is covered by the substantially intact portion of the epidermis of the body, and further wherein the upstream anastomosis forming step includes the step of suturing the one end of the graft to the blood vessel; isolating a region of the area within the blood vessel substantially adjacent the downstream site from fluid communication with the rest of the area in the blood vessel; making an arteriotomy in the sidewall of the blood vessel substantially adjacent the downstream site to create a communicating aperture between the downstream isolated region and the area outside of the blood vessel; and forming an anastomosis between the second end of the graft and the blood vessel substantially adjacent the downstream site.
