Plasticized stent coatings

摘要

A system includes a catheter (110), a stent with a stent framework (120) operably coupled to the catheter and a drug-polymer coating (130) on the stent framework including at least one plasticizer dispersed in the drug-polymer coating. Independent claims are included for the following: (a) a drug-polymer coated stent; and (b) manufacturing the drug-polymer coated stent comprising mixing a polymeric material with solvent to form a solution, dispersing plasticizer into the solution, coating the solution on a stent framework and drying the stent.
