Abstract

A tissue stabilizer is disclosed that comprises a malleable planer foot integrated into a flexible membrane and is useful for stabilizing tissue such as the heart while performing surgery thereon. The malleable planar foot has an open central region and a rigid arm connected to the foot. The membrane integrated with the foot has a shape approximating the foot, a lower section having a bottom surface for contacting the tissue to be stabilized, and an upper section opposite the lower section. The membrane has an inner chamber in fluid communication through an opening with a plurality of suction ports on the bottom surface. An outlet port connects the inner chamber and suction ports to a negative pressure source. The tissue stabilizer has a centrally-located open region through which the tissue to be stabilized can be accessed and is designed so that when the bottom surface of the membrane is positioned on a tissue to be stabilized and a negative pressure is applied to the outlet port, the bottom surface tends to conform to the surface contour of the tissue to be stabilized through the action of suction by the ports and compression by the foot.
