Abstract
An expandable apparatus for use with a surgical probe having a temperature-controlled portion includes at least one thermally-conductive elongated extension member and means for thermally connecting and attaching the extension member to the surgical probe. The expandable apparatus further includes means for attaching and moving the extension member between a closed configuration in which the extension member is substantially parallel to the surgical probe and an open configuration in which the extension member extends radially outward from the surgical probe. A method of using the expandable apparatus to ablate tissue that line a body cavity is also disclosed.
