1. An intravascular balloon catheter comprising:
- a catheter body having a proximal end a distal end, and a guidewire lumen therebetween; and
a first balloon structure having a shaft with a balloon inflation lumen, a balloon sleeve fixed at a distal end of the shaft and having an inflatable balloon thereon, and a sleeve passage therethrough which is slidably receivable over the catheter body, wherein said shaft has an axial groove present along at least a portion thereof to removably receive at least a portion of the catheter body, and wherein said shaft extends proximally of the balloon sleeve and has sufficient column strength to advance the balloon structure over the catheter body.

Abstract
An intravascular balloon catheter includes a tubular catheter body having a balloon structure removably mounted over the catheter body. The catheter body has a guidewire lumen, and the catheter body may be left in place within a patient'"'"'s vasculature while the balloon structure is withdrawn and optionally a second balloon structure introduced over the catheter body. The catheter and methods of the present invention are particularly suitable for performing angioplasty and subsequent procedures, such as stent placement, which are best performed using successive interventional balloon structures.
