ABSTRACT:
An exchange catheter facilitates the replacement of an existing guiding catheter with a larger guiding catheter during catheterization procedures such as percutaneous transluminal coronary angioplasty without disturbing the position of a guidewire. The exchange catheter has a distal portion through which a guidewire is slidable. The outer diameter of the distal portion is slightly less than the inner diameter of the existing guiding catheter. A femoral sheath is slidable over the proximal portion of the exchange catheter so as to facilitate femoral sheath exchange.
