CATHETER WITH CRYOGENIC AND ELECTRICAL HEATING ABLATION
摘要
A catheter (110) for the cryotreatment of tissue includes a catheter body (110b) and a treatment (110c) tip positioned at the distal end of the cathet er body. The treatment tip has a cooling segment operable at a temperature sufficient to freeze tissue and an electrically-driven ablation assembly operable to apply heating ablation energy to the tissue. The cooling segment has a thermally conductive wall for contacting and thermally treating tissue in contact with the thermally conductive wall. The cooling segment and the electrically-driven heating ablation are controlable to effect tissue ablati on.
