George S Abela: Laser method and apparatus for the recanalization of vessels and the treatment of other cardiac conditions. University of Florida, Dennis P Clarke, August 29, 1989: US04860743 (136 worldwide citation)

Cardiac conditions such as blockages in arteries caused by plaque build-up are treated intravascularly with laser radiation using an optical fiber having a heat conducting end cap on its distal end. A spherical lens within the end cap focuses a small portion of the laser energy directly into the pla ...

George S Abela, Stephan E Friedl: Laser treatment apparatus and method. University of Florida, Kerkam Stowell Kondracki & Clarke, October 29, 1991: US05061265 (78 worldwide citation)

An apparatus for performing ablation upon a patient using laser energy. The apparatus advantageously provides for a laser beam to directly strike the tissue of a patient by having the laser beam pass out an opening in an outer hood. To prevent the apparatus from becoming fouled by burnt red blood ce ...
