Abstract

An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may directly cool tissue contacting the balloon (212), or may cool a separate internal chamber. In the first case, the coolant also inflates the balloon, and spent coolant is returned to the handle via a return passage extending through the body of the catheter.Plural balloons may be provided, wherein a secondary outer balloon (212) surrounds a primary inner balloon (203), the primary balloon being filled with coolant and acting as the cooling chamber. The secondary balloon is coupled to a vacuum return lumen (205) to serve as a robust leak containment device and thermal insulator around the cooling chamber.
