Claim Text:
1. A balloon catheter comprising: a main catheter shaft including a guidewire lumen and an inflation lumen; a balloon extending from a distal end of the main catheter shaft, wherein the inflation lumen of the main catheter shaft is in fluid communication with an interior of the balloon; a deformable guidewire shaft extending from a distal end of the main catheter shaft, adjacent and external to the balloon, wherein the deformable guidewire shaft defines a lumen in fluid communication with the guidewire lumen of the main catheter shaft; a proximal bond that fixes a proximal end of the balloon to a distal end of the main catheter shaft; and a distal bond that fixes a distal end of the balloon to a distal end of the deformable guidewire shaft, wherein an outer surface of the deformable guidewire shaft between the proximal and distal bonds is not bonded to the balloon, and wherein balloon inflation causes the balloon and the deformable guidewire shaft to bend in radially opposing directions, thereby orienting the distal end of the deformable guidewire shaft in a direction different from that of the main catheter shaft.
