Abstract
The present invention is directed to new and useful methods and apparatus for isolating and immobilizing tissue for improved presentation in a surgical site, preferably in coronary bypass on a beating heart. At the same time, the present invention also helps avert ischemic damage to tissues downstream. A surgical stabilizer in accordance with the present invention offers physical manipulation of a surgical site, which improves the surgeon's sewing, grasping, and visualizing abilities at the site, and in turn, may increase the confidence and patency of the graft. The stabilizer is used to compress or to suction a region of the heart just below a stenotic coronary artery. The surgeon may selectively articulate the tissue by spreading it apart or pushing it together, as per his or her preference, or per the requirements of the surgical situation. The surgeon may lock in place the handle via a ratchet mechanism to hold the specific open or closed articulation of the surgical stabilizer. With the tissue thus isolated and immobilized, the surgeon may then graft the bypass vessel distal to the stenosis in the coronary artery.
