CATHETER SYSTEMS FOR HAVING BOTH A THERMODILUTION ACTION AND A BODY OBSTRUCTION DESTRUCTION ACTION, AND METHODS FOR DETERMINING BLOOD FLOW RATES AND FOR PERFORMING BODY OBSTRUCTION DESTRUCTION
A catheter system and a method for performing body obstruction destruction are disclosed. The catheter comprises a catheter shaft comprising a proximal end and a distal end, including an outer tubular member and at least one inner tubular member disposed within the outer tubular member； a first fluid lumen defined between the inner tubular member and the outer tubular member and at least one second lumen defined by the inner tubular member； one or more fluid exit openings located at a distal end region of the catheter configured to permit fluid to exit the catheter from the first fluid lumen； fluid pressure means located external of the catheter ahead from the proximal end for delivering said fluid in the first fluid lumen at a pressure range predetermined to cause destruction of said obstruction.
