摘要：
A surgical instrument includes a flexible tube defining a proximal end and a distal end. An end effector, disposed at the distal end of the flexible tube, is configured for insertion into and advancement through a body cavity to a treatment target. The end effector is adapted to connect to a source of energy. The end effector includes an expandable member which can expand from an un-expanded state to an expanded state in order to circumferentially contact a bodily treatment target. The end effector further includes at least one heating member that may hear the expandable member such that the expandable member may thermally treat tissue that the expandable member contacts.
