<p>An indwelling catherer has a flexible tubular member with a main lumen for urine discharge, one end of the main lumen being closed. An aperture is provided adjacent the closed end of the main lumen to communicate same with the exterior of the tubular member. A balloon is disposed at the aperture. The balloon is inflatable by an auxiliary lumen. The periphery of the tubular member is provided with a layer of oligodynamically active metal producing metal ions upon contact with the urine, to thus reduce the danger of urinary tract infections.</p> |
