Abstract
The invention provides implantable sustained release bioactive agent delivery devices that include 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 a surface of the body member, the polymeric coated composition including a first polymer, a second polymer, and a bioactive agent. The polymeric coated composition is formulated to provide controlled release of bioactive agent over time when introduced into physiological conditions. Methods of preparing implantable devices configured and formulated to provide controlled release of bioactive agent are also provided.
