ABSTRACT:
Apparatus and method is disclosed for facilitating balloon catheter exchange in angioplasty procedures. A guide catheter allows the balloon catheter to be inserted into the subject to a region near a treatment region within the vascular system. A fluid source is provided for selectively inflating the balloon. A passageway in the catheter body that extends through the catheter balloon opens into the blood vessel via a sideport. A guidewire passageway extends through a distal most part of the catheter body to allow a guidewire to be inserted into the sideport and routed out the catheter body through a distal opening.
