Abstract
A prosthesis for intraluminal drug delivery can comprise a plurality of interconnected struts that form a tubular scaffold structure. The struts include through-holes with an inner surface configured to retain a bioabsorbable depot. The bioabsorbable depot includes a drug-polymer composition that hydrolytically degrades upon implantation. The inner surface of the through-hole can be an entirely smooth and continuous area that is concave or convex, with no geometric discontinuities. The inner surface of the through-hole can include any number of constricted and distended regions to form grooves of a size and shape carefully selected to engage a corresponding geometric feature of the bioabsorbable depot.
