ABSTRACT:
The present invention is accomplished by providing a catheter with a shaft having a balloon affixed to the distal end, a core wire extending throughout the shaft and throughout the balloon, the core wire having a tube surrounding the distal end, a sleeve defining a guidewire lumen extending parallel, and exterior to the shaft and to the exterior to the balloon. In yet another embodiment the catheter shaft has a balloon affixed to the distal end and a sleeve defining a guidewire lumen extending parallel and exterior to the shaft and to the balloon exterior. In yet another embodiment the catheter shaft has a balloon affixed to the distal end and a core wire extending throughout the shaft and throughout the balloon with the core wire having a tube surrounding the distal end. In each embodiment the balloon is compressed to itself to form a compressed area just distal to the distal balloon cone for separating the balloon inflation lumen from a sleeve lumen. A skive is cut in the balloon just distal to the compressed area to form a proximal port for the sleeve lumen. In the embodiment with a sleeve, the sleeve is affixed to the shaft and balloon as well as the sleeve extending through the sleeve lumen within which the sleeve is affixed.
