## Abstract

Methods for performing minimally invasive heart surgery include accessing a heart of a patient through a first incision on the left thorax of the patient, contacting the heart through the incision with a heart stabilizing device and/or a heart positioning device, introducing at least one coupling device through a second incision on the patient located apart from the first incision, coupling the coupling device with the heart stabilizing device or the heart positioning device, and performing a surgical procedure on the heart. Systems may include a retractor device, a heart stabilizing device, and a coupling device, for enhancing cardiac surgery. Any suitable heart surgery may be performed using methods, devices or systems of the present invention. In one embodiment, a CABG procedure is performed.

## Claims

### Claim 1

A system for enhancing minimally invasive heart surgery, the device comprising:
a surgical tool comprising a ball;
an elongate coupling member comprising a proximal end, a distal end, a flexible rigidifying portion comprising a plurality of pieces and a wire that when tightened locks the pieces of the rigidifying portion into place, a coupling means near the distal end for coupling with the surgical tool, and an actuation device near the proximal end that can tighten the coupling means to the ball of the surgical tool and loosen the coupling means from the ball of the surgical tool; and
an elongate flexible arm for coupling the elongate coupling member with a stable object, the elongate flexible arm comprising a distal clamp configured to clamp the elongate coupling member and a proximal clamp configured to clamp the stable object.
