Abstract

This invention relates to a device for stabilizing a particular area of the heart surface tissue for performing an anastomosis. In one embodiment the invention is comprised of a rectangular flat plate frame stabilizer having a bottom gripping surface for pressing against the surface tissue of the heart and minimizing motion during a heart bypass operation. Opposite closed sides or ends of the rectangular flat plate stabilizer substantially occlude the vessel while the surgery is being performed. A gap or opening in a side of the stabilizer allows for removal after the operation is completed. Various methods are described for locking the position of the stabilizer once it is pressed firmly in position against surface tissue of the heart. In one embodiment a knurled cylindrical rail is mounted on the stabilizer and engages a socket in a rigid shaft. A locking mechanism is provided by a pin and a handle for locking the rail in the socket in the rigid shaft. Other embodiments include a ball and socket mechanism that allows a wide range of adjustments, a hinged end on the rectangular frame to allow the stabilizer to be closed when the surgical procedure is being performed and an embodiment that allows external adjustment of the rectangular flat plate frame stabilizing plate against heart surface tissue from outside the surgical site.
