Abstract
Abstract An intravascular catheter, comprising a catheter shaft having a proximal end, a distal portion, and a distal end, having diagnostic or therapeutic means mounted on the distal portion, 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.
