Claim 4:
5. The in-vivo implantable prosthesis of claim 1, which is characterized in being manufactured by applying the coating composition comprising a photoinitiator, a crosslinking agent, and a phosphorylcholine monomer having an acrylate group to the surface of the in-vivo implantable prosthesis; and irradiating UV rays onto the in-vivo implantable prosthesis to which the coating composition is applied, thereby forming crosslinked polyphosphorylcholine which is covalently bonded with the external surface of the in-vivo implantable prosthesis,
wherein the external surface material of the in-vivo implantable prosthesis comprises polydimethylsiloxane having functional groups which provide the radicals that react with the terminal C═C bond of the acrylate group of phosphorylcholine via the photoinitiator to form the covalent bonds.
