Abstract
A device for effecting myocardial perfusion is described. The described device comprises a plunger or catheter disposed within a capsule having bulbous members having appended thereto slit needles which are capable of perforating myocardium. The plunger is spring loaded and, when activated, causes the slit needles to emerge from the capsule and excise portions of the myocardium, so permitting perfusion at such sites. Perforation of the myocardium may also be affected by means of a laser beam directed through the luminia of the needle. Use of the described device eliminates long post open heart recovery, and permits patients to return to a productive life shortly after surgery.
