Patent Images
1. A method of coating a stent comprising:
- providing a stent;
providing a coating composition comprising an HMG-CoA reductase inhibitor in an amount of about 1 to 50 wt. %, and a polymeric biodegradable carrier component comprising a polymer selected from polycaprolactone, ethylene-vinyl acetate polymer, and a two-part silicone rubber;
expanding the stent to an increased diameter; and
applying the coating composition to the stent,wherein the HMG-CoA reductase inhibitor is released from the stent at a rate of >
20 μ
g/ml per day.

Abstract
Stents with coatings comprising a combination of a restenosis inhibitor comprising an HMG-CoA reductase inhibitor and a carrier. Also provided are methods of coating stents with a combination of an HMG-CoA reductase inhibitor and a carrier. A preferred example of a restenosis inhibitor is cerivastatin. The stent coatings have been shown to release restenosis inhibitors in their active forms.

6. A method of coating a stent comprising:
-
providing a stent; providing a first coating composition comprising a first carrier and an HMG-CoA reductase inhibitor in an amount from about 1 to 50 wt. % of the first coating composition; expanding the stent to an increased diameter; applying the first coating composition to the stent; drying the stent after the first coating composition is applied to the stent; and applying a second coating composition comprising a polymeric biodegradable carrier to the dried stent. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
