Patent ID: 7101367

Claim:
An expandable apparatus for use with a surgical probe having a temperature-controlled portion, comprising: at least one thermally-conductive elongated extension member including a first extension member and a second extension member, said first extension member having a distal end and said second extension member having a distal end; thermal connection means for providing a thermal connection between said at least one extension member and the temperature-controlled portion of the surgical probe; attaching means for attaching said at least one extension member to the surgical probe such that said at least one extension member is movable between a closed configuration in which said at least one extension member is substantially parallel to the surgical probe and an open configuration in which said at least one extension member extends radially outward from the surgical probe, said attaching means comprising a tubular catheter having a distal end and a thermally-conductive section; moving means for moving said at least one extension member between said closed configuration and said open configuration; and a connecting member at said distal end of said catheter, said connecting member having a first end pivotably connected to said distal end of said first extension member and a second end pivotably connected to said distal end of said second extension member.
