Methods, devices, and coatings for controlled active agent release
First Claim
1. A method for coating a medical device, comprising:
- identifying active agent elution rates for a coating composition applied to substrates at a plurality of coating deposition rates, the coating composition comprising an active agent and a polymer;
selecting one of the plurality of coating deposition rates with a desired active agent elution rate, wherein the selected deposition rate is faster if a faster elution rate is desired and slower if a slower elution rate is desired, andapplying the coating composition to the medical device at the selected deposition rate.

Abstract
The present invention relates to methods, devices, and coatings, wherein active agent release is determined by deposition rate of a coating or material. In an embodiment, the invention includes a method for coating a medical device, including identifying active agent elution rates for a coating composition applied to substrates at a plurality of coating deposition rates, selecting one of the coating deposition rates, and applying the coating composition to the medical device at the selected deposition rate. In an embodiment, the invention includes a combination including a medical device and a composition for coating the surface of a medical device with an active agent in a manner that permits the coated surface to release the active agent over time when implanted in vivo.
