Abstract
Abstract An apparatus for stabilizing a predetermined area on a heart or other organ of a patient to enable a surgical procedure, the apparatus comprising a bifurcated member having two elongated prongs and an elongated handle segment pivotally attached to the bifurcated member. The handle segment can be movably attached to a rib retractor or other surgical device so that a person is not required to hold the handle segment. The apparatus may further comprise an attachment or inlay to prevent lateral movement thereof when being used in the surgical procedure.
