Abstract
A method of thermally treating tissue during a surgical procedure where a surgical access device, including a body member having walls with at least one conduit therein, is inserted into the patient. A chilled fluid is circulated through the at least one conduit such that the tissue that is located proximate the body member is cooled. Alternatively, the body member may be constructed from a highly thermally conductive material such that heat energy is transmitted through the body from the tissue located proximate the body member and into a heat sink. The surgical device may include a first or second blade portions constructed from an inner and an outer shell having walls. Ribs located on the inner shell sealingly coupled to the inner wall of the outer shell to create the at least one conduit within the walls of the blade portion.
