Abstract
The present invention relates generally to a family of fiber optic laser delivery devices for use in medical and other applications, and more particularly, to such an apparatus wherein the transmitted radiation is delivered through and at various angles to the central axis of a fiber optic waveguide by an internally reflective surface. The invention is capable of coagulating, cutting or vaporizing tissue and may be useful in a wide range of surgical and non-surgical applications. A novel method for coagulating and then vaporizing or otherwise removing the coagulated tissue is also disclosed.
