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 ventricular cavity without penetrating full thickness of wall. A catheter has a fiber optic connected at its handling end to laser, terminates insertable catheter. servomotor controls advancing stop positions relative At each position another channel created. An aiming beam aids directing forming different desired positions.
