    • PROBLEM TO BE SOLVED: To provide a delivery device for controlled delivery of one or more bioactive agents to a treatment site within body. SOLUTION: The invention relates to 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 including a first polymer, a second polymer, and a bioactive agent in contact with a surface of the body member. In the device, the first polymer comprises polyalkyl(meth)acrylic acid, aromatic poly(meth)acrylic acid, or a combination of polyalkyl(meth)acrylic acid and aromatic poly(meth)acrylic acid, and the second polymer comprises ethylene-vinyl acetic acid copolymer.
