Abstract
A urinary catheter is provided that reduces the likelihood of infection. The catheter includes a distal end positioned in a bladder. The distal end utilizes an inflated balloon that is positioned in the bladder to prevent removal of the distal end of the catheter from the bladder. The balloon, when inflated, contacts areas of the bladder that are spaced away from the urethral opening and from the trigone in the bladder. Urine drainage openings are formed in the distal end, are positioned laterally from the balloon, and can extend down to the inner surface of the bladder to facilitate drainage of urine from the bladder formed takes on a tapered configuration that reduces pressure on the trigone. The catheter incorporates one-way valves which function to make the catheter a close system that minimizes the risk of infection. Spaced apart concentrations of silver and zinc are incorporated on the inner and outer surfaces of the catheter to further reduce the risk of infection.
