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.
Claims
exact text as granted — not AI-modified1 . A coated stent comprising a stent and a coating composition comprising a biologically active component and a biodegradable carrier component, the biodegradable carrier having a melting point of about 50° C. or less.
