Abstract:
1. A stent comprising a coating deposited thereon, the coating comprising at least two layers, the first layer comprising a PLGA-PEG-PLGA triblock copolymer, the first layer being deposited on a second layer, the second layer comprising a biostable polymer; wherein PLGA in the PLGA-PEG-PLGA triblock copolymer is a block of poly(D,L-lactide-co-glycolide) and PEG in the PLGA-PEG-PLGA triblock copolymer is a block of poly(ethylene glycol); wherein the PLGA-PEG-PLGA triblock copolymer has a weight average molecular weight (Mw) from about 50 kDa to about 200 kDa and comprises: and wherein the PLGA-PEG-PLGA triblock copolymer of the first layer breaks into fragments upon exposure of the coating to a physiological environment.
