Abstract:
A catheter for vessel treatment, comprising:a temperature sensor for detecting a temperature increase on a vessel wall indicative of the location of a vulnerable plaque; a balloon for performing cryoablation on the vessel wall for vulnerable plaque treatment so as to inhibit inflammatory response in the vulnerable plaque while preserving anhydrous cellular structure thereof; a first lumen for supporting the balloon; a second lumen for providing cryogenic fluid to the balloon to inflate the balloon; a third lumen for returning cryogentic fluid from the balloon; a larger marker near a distal end of the catheter for joining together the first lumen and the second lumen; and a smaller marker at a proximal area of the catheter for joining together the first lumen, the second lumen, and the third lumen.
