  • Publication number: 20060013835
    Abstract: The invention provides a controlled release bioactive agent delivery device for treatment of an eye 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 a surface of the body member, the polymeric coated composition including a first polymer, a second polymer, and a bioactive agent. The first polymer and the second polymer are hydrophobic, and the body member has a length such that, upon placement of the device at an implantation site within a posterior segment of an eye, the device does not enter a central visual field of the eye. The invention also provides methods method of delivering bioactive agent to a posterior region of an eye.
