## Abstract

An illuminated microsurgical probe may include a handle, a diffuser, an aspiration conduit, and an optic fiber bundle. The diffuser may include a diffuser distal end, a diffuser proximal end, and a diffuser inner bore. The handle may include a handle distal end, a handle proximal end, and a handle inner bore. The aspiration conduit may include an aspiration conduit distal end and an aspiration conduit proximal end. The aspiration conduit distal end may be disposed in the diffuser inner bore and the aspiration conduit proximal end may be disposed in the handle inner bore. The optic fiber bundle may include an optic fiber bundle distal end and an optic fiber bundle proximal end. The optic fiber bundle distal end may be disposed in the diffuser inner bore.
