Claim Text:
1. A method of making an implantable, intraluminal prosthesis, the method comprising: forming a tubular frame of interconnected structural members; forming through-holes in the structural members; forming an indentation in an inner surface of each of the through-holes; and forming a bioabsorbable depot in each of the through-holes, comprising forming a protrusion of the bioabsorbable depot that engages the indentation of the through-hole in which the bioabsorbable depot is retained, wherein engagement of the protrusion with the indentation prevents the bioabsorbable depot from sliding out an end opening of the through-hole, and wherein forming the protrusion is performed using a bioabsorbable polymer that is more resistant to hydrolytic degradation than a bioabsorbable polymer of another part of the bioabsorbable depot.
