ABSTRACT:
An angioplasty catheter, comprising a catheter shaft having a proximal end and a distal end, with a balloon inflation lumen extending therethrough, a fixed, steerable torquewire extending through at least a portion of the shaft and out of the distal end thereof, an angioplasty balloon on the distal end of the catheter operatively communicating with the balloon inflation lumen for inflation and deflation of the balloon, wherein the proximal end of the balloon is attached to the distal end of the catheter shaft and the distal end of the balloon is attached to the torquewire, and a bailout lumen extending along the catheter shaft from a point ordinarily outside the patient during use to a point proximal of the balloon and normally inside the patient during such use, the bailout lumen adapted to receive a removable guidewire and having an outer wall, with the outer wall preferably including a means such as a longitudinally extending slit for laterally removing the catheter from the patient and off of the guidewire while maintaining the position of the guidewire in the patient, and optionally including a side port through the outer wall of the bailout lumen through which a guidewire can be inserted. Methods for using the catheter are also disclosed.
