Laser coronary angioplasty using carbon monoxide lasers

A study was made of a laser angioplasty system using a CO laser, 5 mu m in wavelength. To achieve therapeutic irradiation in a water solution, the authors developed a contact CO laser irradiation method which uses an optical fiber to carry the laser beam to the lesion. The authors have also developed a thin coronary angioscope catheter for diagnosis and targeting of this therapy. >
