Slipover urethral instrument system.

An inovative system has been devised using an elongated hollow guide and slipover urethral instruments. Inherent in this concept are many safety features. A slipover follower and sound will replace current instruments with the threaded locking mechanism. The versatility of the system is demonstrated by the passage of the Councill catheter, cystoscope and direct vision urethrotome over the guide. The orderly interaction of all instruments facilitates their use.
