Abstract
A method and apparatus are described for percutaneous myocardial revascularization of a human heart. A deflectable elongated flexible lasing apparatus is used which includes a source of laser radiation, an elongated flexible radiation conveying member for conducting the laser radiation to a lens on the distal end of the radiation conveying member for focusing the laser radiation, and control lines for deflecting the distal end of the radiation conveying member. The control lines are secured to the distal end of the radiation conveying member for changing the angle of deflection of the distal end of the radiation conveying member. The lasing apparatus is guided to an area within the patient's heart, and the distal end of the lasing apparatus is directed to an area of interest where the inner wall of the heart is irradiated with laser energy to form a channel through the myocardium for a desired distance. In a preferred embodiment, channels are formed without perforating the epicardium of the heart.
