XeCl laser ablation of atherosclerotic aorta tissue was investigated. Luminescence spectra of ablation products were measured for soft and hard arterial tissues. A pronounced difference observed between plume luminescence for various plaques and norm

Autofluorescence spectroscopy of arterial surfaces provides information about the distribution and composition of atherosclerotic plaques. The aim of the study was to determine whether accumulation of peroxidized lipoproteins in arterial walls, a pro

The energetics of 308-nm excimer laser irradiation of human aorta were studied. The heat generation that occurred during laser irradiation of atherosclerotic aorta equaled the absorbed laser energy minus the fraction of energy for escaping fluorescen

A theoretical description of the ultraviolet laser etching process is developed. The model is based on an analysis of radiation transport at high intensities, and the results agree well with all available experimental etch data for organic polymers.

An in vitro investigation has been performed to assess the possibility of removing occlusive arterial thrombi with excimer laser ultraviolet light delivered by flexible optical fiber. Results indicate that such a procedure would produce small debris

Summary form only given. Although excimer laser refractive surgery has been available in the United States for a year-and longer elsewhere-the fundamental mechanisms of photoablation are still not fully understood. Consequently, the motivation for co

Excimer lasers emit light energy, short optical pulses at ultraviolet wavelengths, that results in a unique laser tissue interaction. This has led to an increasing number of studies into medical applications of these lasers in fields such as ophthalm
