ABSTRACT:
An illumination device for use in surgery on the human body has a optical fiber which terminates distally in a bullet-shaped tip. The tip has an exterior surface which is a surface of revolution of a predetermined curve about the longitudinal axis of the tip, the predetermined curve having a first proximal segment, a second intermediate segment, and a third distal segment. The first segment has tangents substantially all of which make less than a first predetermined angle with the longitudinal axis. The second segment has tangents substantially all of which make angles with the longitudinal axis which are greater than the first predetermined angle and less than a second predetermined angle. The third segment has tangents substantially all of which make angles with the longitudinal axis which are greater than the second predetermined angle. A method of manufacturing the tip is disclosed as well.
