A urinary catheter is provided that reduces the likelihood of infection. The catheter utilizes a balloon that is positioned in the bladder to prevent removal of the catheter. The balloon, when inflated, 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.
