Rusch - Coude Tip Closed System Catheter is designed for people who experience urinary tract infections with traditional intermittent catheters. A closed system catheter works the same as an intermittent catheter, but is housed within a sterile collection bag. The tip of the catheter also has a protective cap over it that prevents it from being exposed to bacteria within the distal urethra. This catheter also features a bent coude tip that is ideal for maneuvering around urethral strictures or an enlarged prostate. This helps increase comfort for the user.
