Abstract
A balloon catheter for performing angioplasty procedures includes a catheter shaft, a balloon attached to the catheter shaft near the distal end and a channel either attached to or integrally formed on the distal end of the catheter shaft distally of the balloons. The relatively short channel is threaded over a wire guide for advancing the balloon catheter into the vascular system of the patient over the wire guide. The relatively short channel allows the balloon catheter to be advanced along the wire guide with less friction interaction between the balloon catheter and wire guide than in conventional balloon catheters in which the wire guide lumen extends the full length of the catheter.
