Myocardial Revascularization Through The Endocardial Surface Using a Laser

摘要

Myocardial revascularization is performed by an apparatus and method which forms channels in the myocardium from inside the ventricular cavity without penetrating the full thickness of the ventricular all. A catheter has a fibre optic connected at its handling end to a laser, and terminates at the insertable end of the catheter. A servomotor controls the advancing of the fibre to stop positions relative to the catheter. At each stop position another channel is created. An aiming beam aids in directing the channel forming fibre end to different desired channel positions.
