ABSTRACT:
A arterial bypass includes a relatively large diameter proximal tubular segment for connection to the upstream portion of an artery and a relatively small diameter distal tubular segment for connection to the downstream portion of the artery. A tapered adapting segment joins the proximal and distal segments. The distal segment is coupled to the downstream portion of the artery by way of a connector element. The connector element includes an entrance member, a coupled, angularly offset exit member and a heel member. The exit and heel members are adapted for insertion through an arteriotomy and into the vessel. The exit member outer diameter is matched to the vessel inner diameter near the arteriotomy.
