ThermoCool SF Catheter contains porous tip which facilitates uniform cooling and minimizes the risk associated with thrombus formation. The half flow rate eases the fluid management process and provides an optimized cooling. The catheter regardless of orientation provides enhanced and efficient cooling with its various features such as porous tip, hollow tip, diverters and centralized sensor. The thin and strong walls facilitate an efficient internal and external cooling. The device ensures less risk of fluid overload in patients with left verticular dysfunction of renal failure. Successful lesions are achieved through the special design of the device for high level power duration.
