Abstract

A method of forming an implantable article includes providing a biodegradable polymer including anti-thrombogenic groups along the length of the biodegradable polymer, biodegradable groups in the backbone of the biodegradable polymer and a plurality of functional groups adapted to react with reactive functional groups on a surface of the implantable article, and reacting at least a portion of the plurality of functional groups with the reactive functional groups on the surface of the implantable article.
