HR Healthcare closed system intermittent catheters, inclusive of our soft introducer tip, are designed to reduce risk of recurrent Urinary Tract Infections. For many potential users, catheter insertion is very difficult using ordinary closed systems, since the tube will slip back into the bag. Fine motor use of the fingers, the ability to pinch, and then to hold the tube stable, are required to use other brands. With the patented HR Healthcare EZ-Advancer® valve, holding the tube in place, there is no retraction. If you’ve experienced difficulty advancing any other catheter, we ask you to try MTG.
