ABSTRACT:
Apparatus and method is disclosed relating to a rapid exchange perfusion and infusion balloon catheter for treating a blood vessel with a treatment fluid. A guide catheter allows the balloon catheter to be inserted into the subject and placed near a treatment region within the vascular system. A fluid source is used to selectively inflate an infusion balloon. A guide wire tube having perfusion holes and extending through the balloon allows continuous blood flow while the balloon is inflated. An exit spaced along the guide wire tube allows the infusion balloon catheter to be rapidly exchanged with another infusion balloon catheter without having to remove the guide wire from its position within the subject.
