1. A method for controlling the rate of release of a bioactive agent from a coating composition provided in vivo, the method comprising the steps of:

  • a) providing a composition comprising a bioactive agent in combination with a plurality of polymers, including a first polymer component selected from the group consisting of polyalkyl(meth)acrylates having alkyl chain lengths from 2 to 8 carbons and aromatic poly(meth)acrylates, and a second polymer component comprising poly(ethylene-co-vinyl acetate) having vinyl acetate concentrations of between about 8% and about 90% by weight, and b) applying the coating composition to a surface to provide a controlled bioactive agent release profile in vivo.
