Theoretic model of myocardial revascularization by far infrared laser and experimental validation

Abstract

A theoretic model of myocardial revascularization by a far infrared laser has been established and a quantificational relationship between the aperture of laser channel and parameters of laser has been concluded according to thermodynamics and the law of interaction of far infrared laser and myocardium. The experiment of a carbon dioxide laser revascularization in porcine myocardium has been done for different laser powers and irradiation time. The relative errors between experimental result and theoretic computation are from 13% to 22%. The reasons that cause the errors have been studied in detail.
