ABSTRACT:
A method for treating myocardium using at least one mechanical or electromagnetic energy functional device for forming a network of branched, interconnecting passages in a boundary between endocardium and myocardium, thereby enhancing blood flow into the treated zone, and a device for selectively treating ischemic myocardium tissue comprising a tube having proximal end and distal end, and at least one hollow lumen and defining an axis, at least two mechanical or electromagnetic energy functional devices disposed within the tube, the at least two mechanical or electromagnetic energy functional devices each having a distal end disposed adjacent the distal end of the central tube, and a deflecting member adjacent the distal portion of the central tube for deflecting the distal end of each of the at least two mechanical or electromagnetic energy functional devices away from the axis, for enabling treatment of selective areas of ischemic or hibernating myocardium tissue.
