Abstract

A method for surgically enlarging an arterial lumen totally occluded by a stenotic lesion, and a unique balloon catheter used during that operation. The balloon catheter (70) is generally rod-shaped and includes an elongated tubular member (76) having a double central lumen with a proximal end and a distal end and a balloon (74) portion having a concave distal tip (121) smaller in diameter than the proximal tip (126). The method takes advantage of the catheter design and includes positioning of the catheter in close proximity to and in a stable condition relative to a total occlusion and inflating the balloon to form a plaque cleft.
