Abstract

A method and device for first irradiating a region of tissue with a radiation source, and then incising the region with a mechanical cutting instrument (e.g., a scalpel). Irradiation allows for effective heating of the tissue, which results in blood vessel contraction or coagulation of the blood before the actual incision is made; once the tissue is incised, the resulting flow of blood is low.
