Abstract

Abstract A method provides a closed-chest formation of a channel in a wall of a heart. A transmyocardial revascularisation energy delivery device is introduced through a first minimally invasive penetration of a patient's chest. Sufficient energy if delivered from the wave guide e.g. by a laser to the wall of the heart to form a channel through at least a portion of the wall. The device comprises a visualization member like a CCD-camera.
