A method for performing through-port off-pump beating heart coronary artery bypass surgery is provided. A port device is positioned in the chest wall and directed as necessary. A heart stabilizer is coupled to the port, and operated to apply a compressive force against the heart wall surrounding a location of the required bypass such that the location is substantially immobilized. An instrument stabilizer includes a cannula which is inserted through a hole in the chest cavity, and the distal tip of the cannula is located adjacent the surgical site. The instrument stabilizer dampens movement of a surgical instrument, e.g., a scalpel or needle holder, extended therethrough. Once the bypass procedure is complete, the instruments, heart stabilizer, instrument stabilizers, and port are removed from the body of the patient.
