Multi-lobe balloon for cryoablation

机译:用于冷冻的多凸角气球

摘要

A cryotreatment catheter for treating tissue. The catheter may include an outer elongate body, a balloon treatment element coupled to the distal portion of the elongate body with a plurality of balloon lobes radially arranged around the outer elongate body, an inner elongate body rotatably movable within the lumen of the outer elongate body, and a fluid delivery lumen located within the lumen of the outer elongate body and at least partially within the lumen of the inner elongate body. The fluid delivery lumen may be branched at a distal portion into a plurality of linear segments, each linear segment being in fluid communication with one of the plurality of balloon lobes. Each of the balloon lobes may be inflated independently of each other by the linear segments of the fluid delivery lumen.
