Abstract
An illuminated microsurgical instrument comprises a distally projecting tubular member arranged to perform a medical procedure at an interventional site, a sheath member surrounding a portion of the tubular member, and an optical fiber extending along a length of the outer surface of the tubular member between the tubular member and the sheath member. A method of manufacturing an illuminated microsurgical instrument comprises placing an optical fiber on a positioning member, placing a sheath member around the optical fiber and positioning member and securing the sheath member to the optical fiber, removing material from a distal end of the sheath member and optical fiber at a non-perpendicular angle with respect to a longitudinal axis of the positioning member, removing the positioning member from within the sheath member, and placing the sheath member with the optical fiber secured thereto around a distally projecting tubular member.
