Medical instruments that exhibit surface lubricity when wetted

摘要

This invention provides a medical instrument having on a surface a layer (surface lubricating layer) that forms a hydrogel when wetted and that is composed of an insolubilized water-soluble or water-swellable polymer having a reactive functional group in the molecule. The surface having outstanding surface lubricity and, optionally, the ability to prevent the formation of thrombi. $$
