ABSTRACT:
A fixed wire balloon dilatation catheter usable in angioplasty is provided with a connection between the guidewire and the catheter which can be ruptured so as to detach the catheter shaft and balloon from the guidewire. The guidewire then can be extended by attaching an extension wire to the proximal end of the guidewire. The catheter shaft and balloon then may be withdrawn from the patient while the guidewire position is maintained. A second catheter then may be advanced over the extended guidewire. In accordance with the method of the present invention, the guidewire is not extended when the second catheter is a monorail catheter.
