Abstract
This invention is in the field of controlled elution devices for therapeutic delivery. There exists a need for a stand-alone capable device for the localized and extended delivery of a therapeutic. This need is overcome by the present invention having an examplary embodiment comprised of a microfilm base (12), a reservoir of a therapeutic (14) disposed about the microfilm base (12) and a top layer (24) that is (i) a plurality of laminated layers (24) of para-xylyelne polymer and/or (ii) para-xylyelne polymer endowed with oxidatively functionalized para-xyele units. The thicknesses of the device is optimally in the range of about 10 to about 200 microns. The device is usable for the localized release of broad spectrum therapeutics for interventional and preventative medicine.
