Abstract
A method for forming liquid coatings for medical devices such as stents and angioplasty balloons is provided. The liquid coatings can be made from biodegradable materials in liquid, low melting solid, or wax forms, which preferably degrade in the body without producing potentially harmful fragments. The liquid coatings may also contain biologically active components, which are released from the coatings through diffusion from the coatings and the degradation of the coatings.
