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.

Un cathéter d'échange facilite le remplacement d'un cathéter de guidage existant par un cathéter de guidage plus gros pendant des procédures de cathétérisation, telle qu'une angioplastie coronaire transluminale percutanée, sans affecter la position d'un fil-guide. Ce cathéter d'échange présente une partie distale à travers laquelle peut coulisser un fil-guide. Le diamètre extérieur de la partie distale est légèrement inférieur au diamètre intérieur du cathéter de guidage existant. Un manchon fémoral peut coulisser sur la partie proximale du cathéter d'échange, ce qui facilite l'échange d'un manchon fémoral.
