Abstract
The present invention provides methods and devices for controlling a cold slurry that is delivered to a target tissue and for limiting heat transferring from surrounding tissue to the target tissue. In particular, a balloon structure is deployed at or near a point of delivery to act as a physical and/or thermal barrier. In some instances, the balloon structure can act as a pressure device obstructing the flow of warm blood into a treatment area, which can melt the cold slurry.
Claims19
A device for controlling tissue temperature, the device comprising:
- a first cannula for delivering a cold slurry directly to a target tissue underneath a patient's skin, thereby directly contacting and cooling the target tissue, the first cannula comprising a first open distal end and a first proximal end in fluid communication with a source of cold slurry;
- a second cannula comprising a second open distal end and a second proximal end in fluid communication with a source of a thermal insulator;
- and
- a balloon disposed around the second open distal end of the second cannula and positioned at or near tissue surrounding the target tissue, the balloon comprising a volume filled with the thermal insulator delivered through the second cannula, wherein the filled balloon limits heat from transferring from the surrounding tissue to the target tissue.
