Abstract
The present invention involves a system for transmyocardial revascularization of a beating heart, including a laser device for ablating wall tissue of the heart being treated, with a pacemaker connected to the heart being treated, to provide electrical signals to control the cardiac cycle of that heart, and a conditioning circuit connected to both the pacemaker and to the laser, to permit the controlled 'safe period' firing of the laser. The laser includes an optic waveguide articulably arranged to irradiate the wall of the heart. The conditioning circuit is programmed to permit the firing of the laser upon the time of the cardiac cycle of the heart during a non-ventricular repolarization time period.
