Abstract
Abstract The present invention relates generally to a family of fiber optic laser beam angle delivery devices for use in medical procedures such as a laser assisted transurethral resection of the prostate (TURP) and other applications, and more particularly, to such devices wherein the transmitted radiation is delivered through and at various angles to the central axis of an optical fiber by refraction or reflection off of a reflective insert or other reflective layer placed adjacent to and in intimate contact with the tip of the optical fiber, the tip assembly being encased by a quartz or other transparent material cap, the transparent cap being held secusely in place by an attachment means.
