Patent ID: 7276045

Claim:
A catheter comprising: a proximal shaft having a proximal end, a distal end and an inflation lumen; a distal shaft indirectly connected at a proximal end to the distal end of the proximal shaft and having an inflation lumen in fluid communication with the inflation lumen of the proximal shaft, wherein the distal shaft includes a guidewire shaft having a guidewire lumen; an exchange joint located adjacent the proximal end of the distal shaft for access to the guidewire lumen; and a catheter conversion shaft having a proximal end and a distal end with a guidewire lumen, the catheter conversion shaft having a clip portion at the distal end thereof for detachably securing the catheter conversion shaft over the exchange joint of the catheter such that the guidewire lumen thereof is in communication with the guidewire lumen of the distal shaft wherein the exchange joint is located in a transition shaft of the catheter that includes an outer surface and an outer diameter, wherein the clip portion includes an inner surface and an inner diameter, wherein the inner diameter of the clip portion and the outer diameter of the transition shaft are substantially the same size, such that the clip portion of the catheter conversion portion may be frictionally fit on the transition shaft of the catheter.
