摘要：An apparatus for forming a non-circular opening in tissue includes an elongatebody having a first tissue engaging edge associated with a distal end portion thereof, apunch head disposed adjacent the distal end portion of the elongate body, and defining asecond tissue engaging edge associated therewith. The first and second tissue engagingedges each define a general racetrack configuration characterized by first and secondopposed straight edge portions interconnected by generally arcuate edge portions. Atleast one of the first and second tissue engaging edges is adapted to cut tissue. Theelongate body and the punch head are adapted for relative movement such that the firstand second tissue engaging edges cooperate to cut tissue disposed therebetween tothereby form a general racetrack-shaped opening in tissue.
