ABSTRACT:
An over-the-wire balloon catheter for use in angioplasty includes a proximal single lumen shaft and a multilumen distal portion on which an inflatable balloon is mounted. The lumen of the shaft acts as a combined inflation lumen and guide wire lumen. In the multilumen distal portion, a distal inflation lumen connects the combined lumen with the interior of the balloon, while the distal guide wire lumen extends through the balloon to provide a passage for a guide wire.
