ABSTRACT:
A friction-reducing coating may be applied to a base material, for example the outer surface of a catheter, to provide a significant reduction in catheter friction, particularly when the friction-reducing coating is hydrated. The coating comprises an intimate mixture of a structural plastic material, for example polyurethane, and high molecular weight poly(ethylene oxide).
