Abstract:
1. A stent comprising: a bioabsorbable prohealing layer configured to promote endothelialization upon exposure to bodily fluids, wherein the prohealing layer comprises an endothelial cell (EDC) binding agent that attracts and binds endothelial cells, wherein the substance is dispersed within a bioabsorbable polymer matrix, wherein a bioabsorbable polymer of the matrix is poly(L-lactide), polyglycolide, poly(ester amide), or poly(L-lactide-co-glycolide); and a bioabsorbable drug-polymer layer on an abluminal surface of the prohealing layer, wherein the drug-polymer layer comprises a drug mixed or dispersed within a bioabsorbable polymer that is the same as the bioabsorbable polymer of the matrix, wherein the stent is completely bioabsorbable and upon implantation in a vessel is configured to completely erode and disappear from the vessel.
