  • Biocompatible coating for a prosthesis and a method of forming the same
    Patent number: 6713119
    Abstract: A coating for a prosthesis, for example a stent, and a composition for forming the coating is disclosed. The coating can serve as a primer, allowing substances, such as polymers, to be effectively secured by the prosthesis. Alternatively, the coating can serve as a reservoir, allowing for the local and sustained release of a therapeutic substance to biological tissues. The composition can be formed from an ethylene vinyl alcohol copolymer and a dimethylsulfoxide solvent, with or without a therapeutic substance. Alternatively, the composition can be formed from an ethylene vinyl alcohol copolymer, a dimethylsulfoxide solvent, and a wetting fluid, with or without a therapeutic substance. The composition is applied to a surface of the prosthesis and essentially all of the dimethylsulfoxide solvent or dimethylsulfoxide solvent/wetting fluid is removed or allowed to evaporate to form the coating.
