BALLOON DESIGN TO ENHANCE COOLING UNIFORMITY |
摘要 |
A device, system, and method for enhancing cooling uniformity and efficiency of cryogenic fluids and providing a treatment element the shape of which can be adjusted for multiple purposes. The device may include a balloon catheter and fluid dispersion element, the fluid dispersion element directing the flow of coolant from a fluid injection element the interior wall of the balloon. The method of changing the shape of the treatment element may include retracting and extending a shaft to which the distal neck of a balloon is coupled, so that the balloon goes from a first shape to a second shape. |
