A flexible, lubricious organic polymeric coating is formed by applying a mixture of an isocyanate, a polyol, poly(ethylene oxide), and carrier liquid to a surface to be coated. The carrier liquid is removed and the mixture reacted to form a polyurethane coating with associated poly(ethylene oxide) giving a highly lubricious, abrasion resistant, flexible coating particularly suitable for use as a protective lubricious coating on devices introduced into the body. |
