Abstract
Abstract An apparatus for stabilizing a predetermined area on a heart of a patient to enable a surgical procedure, the apparatus comprising a bifurcated member having two elongated prongs and an elongated handle segment attached to the bifurcated member. Selected portions of the apparatus can be constructed from a memory metal alloy, such as nitinol, to allow the surgeon to adapt the apparatus to a particular surgical procedure. The bifurcated member can be either fixably or pivotally attached to the handle segment. The apparatus may further comprise an attachment or inlay to prevent lateral movement thereof when being used in the surgical procedure. The apparatus may additionally include a cleat for securing a portion of the surgical thread used during the surgical process. Another aspect of the present invention is a member slidably attached to a portion of the handle segment that is movable between a position compressing an artery to reduce or stop blood flow and a position spaced apart from the artery.
