Abstract

This invention is an apparatus (10) for stabilizing a predetermined area on a heart of a patient to enable a surgical procedure, the apparatus (10) comprising a bifurcated member (20) having two elongated prongs (22), and an elongated handle segment (40) attached to the bifurcated member. Portions are constructed from a memory metal alloy, such as nitinol, to adapt to different surgical procedures. The bifurcated member can be fixedly or pivotally attached to the handle segment. The apparatus may further comprise an attachment to prevent lateral movement thereof when being used in the surgical procedure. The apparatus may additionally include a cleat (70) for securing a portion of the surgical thread during the surgical process. Another aspect of the present invention is a member slidably attached to 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.
