The present invention related to a coring tool for preparing a core or opening through tissue and methods of use thereof. In one embodiment, the present invention include a coring tool including: (a) a frame having proximal and distal directions (b) an operator interface element mounted to the frame and movable between a rest position and an actuated position (c) a coring head having at least one cutting blade, the coring head being mounted to the frame for movement in the proximal and distal directions and (d) a actuation mechanism connected between the coring head and the operator interface element, the actuation mechanism including a selector element having first and second positions, the actuation mechanism being arranged to move the coring head distally responsive to movement of the interface element from the rest position toward the actuated position when the selector element is in the first position, and to move the coring head proximally responsive to movement of the interface element from the rest position toward the actuated position when the selector element is in the second position.
