Abstract
Methods for controlling the release rate and improving the mechanical properties of a stent coating are disclosed.
Claims3
A method comprising:
- exposing a stent coated with everolimus and poly(vinylidene-co-hexafluoropropylene) first to either (1) electron beam radiation in the presence of oxygen or (2) gamma radiation in the presence of oxygen;
- and second, exposing the stent coated with everolimus and poly(vinylidene-co-hexafluoropropylene) to either (1) electron beam radiation under vacuum or (2) gamma radiation under vacuum;
- thereby providing a means for controlling the everolimus release rate and improving the mechanical properties of the coating.
