Abstract:
Disclosed is a stent comprising a bioabsorbable polymeric scaffolding; and a plurality of depots in at least a portion of the scaffolding, wherein the plurality of depots comprise a bioabsorbable material, wherein the degradation rate of all or substantially all of the bioabsorbable polymer of the scaffolding is faster than the degradation rate of all or substantially all of the bioabsorbable material of the depots.
