Abstract:
A device for making channels in the heart from a coronary blood vessel, said device comprising:a laser channeling catheter having a distal segment adapted for insertion into a coronary blood vessel, said laser channeling catheter having a longitudinal axis; said laser channeling catheter comprising a catheter body, an optical fiber for carrying laser light housed within the catheter body, said optical fiber having an optical outlet within the distal segment of the catheter, said optical outlet aligned to emit laser light in the distal direction substantially parallel to the longitudinal axis of the catheter; an optical aperture on the side of the distal segment of the laser channeling catheter; a mirror disposed within the catheter body, distal to the optical outlet and aligned to reflect laser light from the optical outlet radially toward optical aperture; a first balloon disposed on the distal segment of the laser channeling catheter, said balloon located radially opposite the optical aperture; and a first lumen within the laser channeling catheter, said first lumen being in fluid communication with the balloon.
