Abstract: 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.

Abstract: A catheter for the repair of an injured blood vessel, characterized by comprising a multiple-lumen type catheter tube having at least two tubular cavities, at least one dilating member disposed in the distal portion of said catheter tube and adapted to communicate with one of said tubular cavities, a lateral hole for the injection of a blood coagulation accelerant disposed on said catheter tube at the proximal side than said dilating member side and adapted to communicate with the other tubular cavity, and a hub having a plurality of flow conduit communicating severally with said tubular cavities of said catheter tube and adapted to communicate with the proximal portion of said catheter tube.
