Abstract
Abstract A method of implanting a graft in the body of a patient to bypass a segment of a blood vessel includes the steps of: (1) securing a first end of the graft to the blood vessel at a first location while the first location is covered by a substantially intact portion of the epidermis of the body, and (2) securing a second end of the graft to the blood vessel at a second location while the second location is exposed through an incision in the body. The first end securing step comprises the step of securing the first end of the graft to the blood vessel with an expandable stent. The second end securing step comprises the step of suturing the second end of the graft to the blood vessel.
