A surgical instrument includes a frame structure defining proximal, and distal Portions. The proximal portion has an articulating arm (1504) for reposition mounting to a base (1412), and the distal portion supporting a stabilizing member (1502). An attachment mounts (1000) on the stabilizing member, the attachment being configured, and dimensioned such that upon contact with the heart the engaged heart tissue bulges outward. A method of surgery using the attachment includes providing a frame structure defining proximal, and distal portions. The proximal portion is reposition mountable to a base supporting an attachment on the stabilizing member, and engaging heart tissue with the attachment such that the tissue bulges outward to better present the tissue for surgery. |
