ABSTRACT:
The invention provides a system and method for performing less-invasive surgical procedures within a body cavity. In a preferred embodiment, the invention provides a system and method for isolating a surgical site such as an anastomosis between an internal mammary artery and a coronary artery in a thoracoscopic coronary artery bypass grafting procedure. The system comprises a foot (11) pivotally coupled to the distal end of a shaft (3) by a linkage (13). The foot has first and second engaging portions (15, 17) with contact surfaces for engaging a tissue surface. The engaging portions are movable between an open position, where the contact surfaces are separated by a gap, and a collapsed position, where the foot is configured for delivery through the percutaneous penetration. An actuator, at the proximal end of the shaft, can be rotated to pivot the foot about a transverse axis so that the contact surfaces are oriented generally parallel to the surgical site to apply pressure to the tissue structure on both sides of the surgical site.
