A combination catheter and drainage system includes a flexible tubular member oligodynamically treated in part and having an aperture adjacent said one end to allow communication between a main lumen and the exterior of the tubular member, a balloon being provided adjacent the aperture and an auxiliary lumen being connected to the main lumen for inflating the balloon and a urine collecting bag connected to the tubular member via a connector means which is oligodynamically treated. The collecting bag is also provided at its discharge distal end with an oligodynamically active metal device thereby forming a system which is completely closed against entry of ambient microorganisms.

A catheter and drainage system for draining urine from a body cavity comprising, in combination, an indwelling catheter, said catheter comprising a flexible tubular member having a main lumen for urine discharge, one end of said main lumen being closed, said tubular member having an aperture adjacent to said one end to allow communication between said main lumen and the exterior of said tubular member, a balloon provided adjacent said aperture, an auxiliary lumen connected to said main lumen for inflating said balloon, and an oligodynamically active metal deposited on a portion of only the outside periphery of said tubular member for producing metal ions upon contact with the urine; a draining tube, a connector means connecting said main lumen to said drainage tube, said connector means having an oligodynamically active metal providing a barrier against intrusion of ambient organisms into said drainage tube, a urine collecting bag having an inlet, and a tubular sterilizing means having oligodynamic activity connecting said drainage tube to said inlet of said collecting bag.
