Abstract
An external male urinary drainage catheter combined with a collar for facilitating proper fitting of the catheter upon a patient, and the method of using such a catheter/collar combination, are disclosed. The catheter includes a cylindrical section rolled to form a torus that is supported by the collar prior to catheter application, a tapered neck section that extends through the open-ended collar, and an inner sleeve portion that is held in a stretched condition by the collar to help insure placement of the sleeve in sealing engagement with the glans of a patient's penis during the initial stage of catheter application.
