Abstract

In this paper, we demonstrate the possibility as well as usefulness of the usage of CO lasers for the laser coronary angioplasty. CO lasers, approximately 5μm of their wavelength, have strong ablation capacity to water-containing living tissue due to intensive attenuation by water. Accordingly, a precise ablation of intravascular obstruction without a perforation may be possible by the CO laser irradiation. As a fundamental study, the design of the fiber energy delivery of CO lasers for the coronary angioplasty and the ablation effect of the CO laser irradiation to human atheroma are revealed. The CO laser irradiation method in the flushing medium of a coronary angioscope is also discussed.
