Abstract
The method for intra-operative myocardial revascularization of a human heart includes a inserting a portion of an elongated flexible lasing apparatus into the chest cavity of a patient, and lasing channels from the epicardium through the myocardium of the heart, without mechanical tearing of the heart tissue. The apparatus is guided to an area exterior to a ventricle of the patient's heart, and the distal end of the optical fiber apparatus is directed to an area of interest where the exterior wall of the heart is irradiated with laser energy to form a channel through the myocardium.
