Urinary tract catheter
First Claim
1. A urinary catheter system for a bladder including a trigone, an internal orifice, and a urethra, the urethra having a top located in the bladder, said catheter system comprising (a) a urine collection container;
- (b) an inflation system;
(c) an elongate pliable tube having (i) a distal end shaped and dimensioned to be inserted through a urethra into a bladder and including an opening for draining urine from the bladder, a balloon positioned beneath said opening and inflatable into a tapered configuration shaped and dimensioned such that the surface area of the trigone contacted by said balloon is less than the surface area of the top of the urethra contacted by said balloon, (ii) a proximate end extending to said urine collection container and adapted to be located exterior of the urethra when said distal end is inserted in the bladder, (iii) a first channel connecting said opening and said collection container, (iv) a second channel interconnecting said balloon and said inflation system such that said inflation system can be used to inflate said balloon into said tapered configuration, and, (v) an intermediate section adapted to be positioned in the urethra when said distal end is inserted in the bladder.

Abstract
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.
