REINFORCED MONORAIL BALLOON CATHETER

摘要

This invention is a dilation catheter which comprises an elongated catheter shaft (20), a guide wire tube (22), and an angioplasty balloon (24). The distal end of the balloon (24) is attached to the distal portion of the guide wire tube (22), and the proximal portion of the balloon (24) is attached to the distal portion of the catheter shaft (20). A stiffening wire (30) is attached to the inner wall of the catheter shaft (20) at a plurality of points along its length. The distal extremity of the guide wire tube (22) is decreased in size relative to the proximal portion of the guide wire tube (22). A fluid is contained within the guide wire lumen (68).
