ABSTRACT:
A method and apparatus for temporarily immobilizing a local area of tissue. In particular, the present invention provides a method and apparatus for temporarily immobilizing a local area of tissue within a patient's body cavity. In one embodiment, the tissue immobilized is heart tissue to thereby permit surgery on a coronary vessel in that area without significant deterioration of the pumping function of the beating heart. The local area of heart tissue is immobilized to a degree sufficient to permit minimally invasive or micro-surgery on that area of the heart. The apparatus for temporarily immobilizing a local area of tissue includes a first tissue engaging member and a second tissue engaging member coupled to a spreader. The spreader is operated by an actuator to selectively control the movement of the first tissue engager and the second tissue engager. The method for temporarily immobilizing a local area of tissue includes controlling the spreading of the first tissue engaging member and the second tissue engaging member so a selective amount of spreading occurs.
