Abstract
The invention provides a controlled release bioactive agent delivery device that includes a body member having a direction of extension, a longitudinal axis along the direction of extension, and a proximal end and a distal end, wherein at least a portion of the body member deviates from the direction of extension, and a polymeric coated composition in contact with the body member, the polymeric coated composition including a first polymer, a second polymer, and a bioactive agent, wherein the first polymer comprises polyalkyl(meth)acrylate, aromatic poly(meth)acrylate, or a combination of polyalkyl(meth)acrylate and aromatic poly(meth)acrylate, and wherein the second polymer comprises poly(ethylene-co-vinyl acetate). The invention also provides methods of delivering a bioactive agent to a patient in a controlled release manner, as well as methods of making a controlled release bioactive agent delivery device.
