Abstract
A urethral catheter includes a flexible transparent catheter tube, a drainage adapter having a major aperature secured to the proximal end of the catheter tube, a minor aperature axially aligned with the major aperature and a drainage funnel located between the aperatures and a fiber optic member having means on one end for attachment to a light source and a flexible fiber optic strand on the other end thereof extending through the minor and major aperatures and through the interior lumen of the tube with the distal end located adjacent the distal end of the tube. An end portion of the fiber optic within the tube is abraded to provide circumferential illumination extending outwardly of the fiber optic end through the transparent tube. The fiber optic may be axially adjusted within the tube by means of the sliding fit with the minor aperature of the drainage adapter.
