EXPANDABLE DEVICE FOR THERMAL THERAPY

摘要

A method and expandable device for thermally affecting tissue in which there is a fluid conduit. An expandable element includes a wall defining an inner volume. The wall has a tissue contact region which is non-coaxial with the longitudinal axis of the fluid conduit. The tissue contact region is operabl e to have a first contact surface area and a second contact surface area in which the second contact surface area is larger than the first contact surfa ce area. A port is formed through the wall and is in fluid communication with t he fluid conduit.
