ABSTRACT:
A passive perfusion balloon catheter for performing percutaneous transluminal coronary angioplasty allows prolonged dilatations without blocking blood flow through the artery being treated. The passive perfusion balloon catheter includes a dual lumen shaft, a balloon head connected to the distal end of the dual lumen shaft, a balloon mounted around the balloon head, and a distal tip which is connected to and extends distally from balloon. The balloon head defines a blood flow channel through which blood can flow when the balloon is inflated. The blood flow channel is generally aligned with a guide wire lumen of the dual lumen shaft so that a guide wire can extend through the catheter and out the distal tip, and can be partially withdrawn into the guide wire lumen to permit perfusion while the balloon is inflated. If necessary, the guide wire can be reinserted from the guide wire lumen through the flow passage so that the wire can be left in place while the catheter is removed.
