BIOCOMPATIBLE ABRASION RESISTANT COATED SUBSTRATES

摘要

2077072 9211877 PCTABS00014 Biocompatible polymeric coatings are provided which have excellent adhesion to a variety of substrate materials. The biocompatible coatings of the invention are comprised of a poly(alkylene oxide), a poly(carboxylic acid) or a poly(N-vinyl lactam) or mixtures thereof. The polymers adhere to the substrate through a polyisocyanate coating which bonds with the biocompatible coating when dried or irradiated or both. The biocompatible polymeric complexes have utility in medical devices such as catheters.
