A method of preparing a biocompatible polymeric coating includes preparing an aqueous polymer solution by contacting and reacting methacrylic acid and at least one methacrylate or phosphorylcholine. The methacrylate or phosphorylcholine may include hydroxyethyl methacrylate, polyethylene glycol monomethacrylate, or methacryloyloxyethyl phosphorylcholine. An aqueous coupling agent solution is prepared and is either applied to the substrate surface or is mixed with the polymer solution to form a coating solution. If the coupling agent solution was first applied to the substrate surface, the polymer solution is then applied to the primed substrate surface. Alternatively if a coating solution was created, the coating solution is applied to the substrate surface. In either event, the polymer solution and coupling agent solution react with the substrate to form the biocompatible polymeric coating on the substrate surface.

Biocompatible polymeric coating containing therapeutic agents

A method of producing an ultra-high Dk material includes contacting and reacting a fluoroalkyl methacrylate; an alkyl glycol dimethacrylate; a hydrophilic agent, such as methacrylic acid; a hydroxyalkyl tris(trimethylsiloxy)silane; a hydroxyalkyl terminated polydimethylsiloxane; and styrylethyltris(trimethylsiloxy)silane. The reaction is conducted within an inert atmosphere at a pressure of at least 25 pounds per square inch (PSI) and for a period of time and at a temperature sufficient to produce the ultra-high Dk material.

Ultra-high Dk material

A method of preparing a mixed-phase thermoplastic biomaterial comprises contacting and reacting a diol and a graft pre-polymer comprising a diol and at least one covalently bonded unsaturated monomer with an organic diisocyanate compound. The reaction is conducted within an aprotic solvent and for a period of time and at a temperature sufficient to produce the mixed-phase thermoplastic biomaterial. The diol may be selected from the group consisting of siloxane diols, polyether diols, polyester diols and polycarbonate diols while the at least one covalently bonded unsaturated monomer may be selected from the group consisting of a fluorinated monomer, a siloxane monomer, an aliphatic ester of methacrylic acid, a cyclic ester of methacrylic acid, a charged monomer, a sulfonium salt, a vinyl monomer with phenol or benzoic acid, N-vinyl pyrrolidone, an aminoglucoside, and a therapeutic agent. The mixed-phase thermoplastic biomaterial may further include an anti-microbial, a therapeutic agent or both.
