Abstract:
A myocardial laser treatment device, comprising:a handpiece having at least one lumen, and having an insertable end and a handling end; a fiber having a diameter and for carrying energy from a laser energy source to a fiber end from which the energy is emitted, said fiber being received in one of the lumens and being movable within the lumen to a position where only the fiber end extends out of the handpiece insertable end, said fiber end, when said fiber is connected to receive energy from a laser energy source, having means for emitting laser energy having a wavelength of about 2.15 micrometers for forming a channel in a ventricular wall from the endocardium to the myocardium having substantially the same width as the fiber diameter to thereby increase myocardial blood flow from the endocardium to the myocardium.
