摘要: A medical instrument comprises a substrate which has at least on its surface a reactive functional group covalently bonded with a water-soluble polymer or derivative thereof, whereby said surface has lubricity when wetted. The water-soluble polymer is a cellulosic polymer, maleic anhydride polymer, polyacrylamide or water-soluble nylon.
The medical instrument is prepared by treating a substrate with a solution of a compound having a reactive functional group to form an undercoat so that the reactive functional group is present at least on the substrate surface, and then treating the substrate with a water-soluble polymer or derivative thereof to covalently bond the reactive functional group with the water-soluble polymer to thereby form a coat of the water-soluble polymer on the undercoat and optionally, contacting the treated substrate with water.-
