    摘要: A medical device having an increased surface hydrophilicity comprises a coating polymer comprising units of a polymerizable hydrophilic compound that is attached to the surface of the medical device via the Michael addition reaction. The coating polymer can be applied to a medical device comprising a hydrogel material. The attachment of the coating polymer may be enhanced by increasing the population of the medical-device surface functional groups before contacting the medical device with the coating polymer.

    摘要: The present invention relates to polymeric compositions useful in the manufacture of biocompatible medical devices. More particularly, the present invention relates to certain cationic random copolymers capable of polymerization to form polymeric compositions having desirable physical characteristics useful in the manufacture of ophthalmic devices. Such properties include the ability to extract the polymerized medical devices with water. This avoids the use of organic solvents as is typical in the art. The polymer compositions comprise polymerized siloxane prepolymer containing pendant cationic and polymerizable groups.

    摘要: A biological coating material that includes a polymerizable polyacrylate monomer; a volatile liquid; a polymer selected from a synthetic rubber, a natural rubber, and a thermoplastic elastomer. The biological liquid coating material forms a coating or bandage in the form of a film that when applied and adhered to a surface or to the skin of a user inhibits the application surface from adhering to another surface.
