Abstract
According to an aspect of the present invention, medical devices are provided which comprise: (a) a substrate and (b) bioerodable polymeric layer over the substrate that contains (i) one or more biodegradable polymers (ii) one or more therapeutic agents, and (iii) one or more plasticizers.
Claims20
A medical device comprising:
- a substrate;
- and
- a bioerodable polymeric layer disposed over the substrate, the bioerodable polymeric layer including poly(lactic acid) or poly(lactic acid-co-glycolic acid) and a plasticizer selected from glycolic acid, an oligomer comprising glycolic acid, and combinations thereof.
A stent comprising:
- a substrate;
- and
- a bioerodable polymeric layer disposed over the substrate, the bioerodable polymeric layer including poly(lactic acid) or poly(lactic acid-co-glycolic acid) and a plasticizer selected from glycolic acid, an oligomer comprising glycolic acid, and combinations thereof.
A stent comprising:
- a substrate;
- and
- a bioerodable polymeric layer disposed over the substrate, the bioerodable polymeric layer including 50 to 99 wt. % of poly(lactic acid) or poly(lactic acid-co-glycolic acid) and 1 to 50 wt. % of glycolic acid and/or an oligomer comprising glycolic acid.
