    摘要： The present invention provides a method and apparatus for treating a vascular occlusion and preventing or reducing ischemic consequences of such an obstruction. The medical device of the present invention may include an elongate body defining a proximal end and a distal end, where the elongate body may also define an injection lumen, an exhaust lumen, and a guidewire lumen. A first expandable element may be coupled to the elongate body, where the first expandable element is in fluid communication with the injection lumen and the exhaust lumen. Further, a perfusion path may be disposed within the elongate body, and a sheath may be movably disposed about at least a portion of the elongate body. The medical device may further include a second expandable element disposed about the elongate body, as well as second inflation and exhaust lumens.

    摘要： A method for inhibiting restenosis includes applying cryogenic energy to a treatment site for a predetermined amount of time. In one embodiment, the treatment site, e.g., a region of an artery dilated by means of a balloon catheter, is cooled to a temperature of about minus fifty degrees Celsius for about two minutes. The application of cryogenic energy inhibits restenosis of the dilated region of the vessel.

    摘要： A cryogenic probe design is provided containing, for example, an inner coil injection tube with a continuous flow of circulating liquid and an outer jacket enclosing the inner coil injection tube. A transducer may monitor parameters in the region between the inner coil injection tube and the outer jacket. An outer jacket serves to prevent gas leakage. One or more embodiments of a probe design provide continuous flow for example via a continuous and controlled path from inlet to outlet and an expanded thermally transmissive region. Expanding a thermally transmissive region of the cooling zone may be provided, for example, in one or more embodiments of injection tube designs.
