Coating irregularities of durable polymer-based drug-eluting stents as assessed by scanning electron microscopy.


AIMS To classify and quantify post-expansion irregularities in durable polymer-based coatings of drug-eluting stents (DES). METHODS AND RESULTS Taxus Liberté, Endeavor Sprint, Endeavor Resolute and Xience V DES (three samples of each) were explored by light microscopy and scanning electron microscopy (SEM) following expansion at 14 atm in water. Incidence… (More)
