Abstract
A method for manipulating a tissue structure within a body cavity provides for retracting and supporting the heart wall to provide access into the heart during a cardiac surgical procedure. In one embodiment of the present invention, a surgical tool support apparatus comprises a base having an atraumatic tissue-engaging surface and an aperture for receiving an elongate tool. The apparatus also has a clamp assembly aligned with the aperture and spaced-apart from a surface of the base opposite to the tissue-engaging surface. The apparatus is particularly useful in maintaining a retracting force on a surgical tool used to manipulate tissue within a body cavity such as the thoracic cavity.
