    摘要： An elongated catheter device (10) with a distal balloon (860) assembly is adapted for endovascular insertion. Coolant injected through the device may, in different embodiments, directly cool tissue contacting the balloon, or may cool a separate internal chamber. Plural balloons may be provided, wherein a secondary outer balloon (865) surrounds a primary inner balloon, the primary balloon being filled with coolant and acting as the cooling chamber, the secondary balloon being coupled to a vacuum return lumen (850) to serve as a robust leak containment device and thermal insulator around the cooling chamber. One or more sensors may be disposed between the balloons or the vacuum return lumen, to detect leaks and control the flow of fluid through the device. Examples of sensors include pressure and temperature sensors, optical sensors, magnetic flow switches and flow meters.

    摘要： The present invention provides a medical device having an elongate body with both a proximal end and a distal end, wherein the elongate body defines an intake lumen and an exhaust lumen. The medical device also has a first pliable element defining a cooling chamber disposed at a point along the elongate body, with the cooling chamber being in fluid communication with the intake lumen and the exhaust lumen. A second pliable element is provided which at least partially encloses the first pliable element, thereby defining a junction between the first and second pliable element. Moreover, a check valve is included which is in fluid communication with the junction between the first pliable element and second pliable element, the valve further being in fluid communication with the exhaust lumen. In addition, the medical device may include sensors or other monitoring means in fluid communication with the junction and the cooling chamber.
