ABSTRACT:
A handpiece for use in transmyocardial revascularization heart-synchronized pulsed laser system includes a barrel having a passage for transmitting a laser beam; a surface at the distal end of the barrel for contacting the wall of the heart; an aperture located at the distal end of the barrel and the enlarged surface for transmitting the laser beam; and means for focusing the laser beam proximate to the aperture to vaporize the tissue of the heart wall and create a hole to the interior heart chamber.
