  • Publication number: 20150202161
    Abstract: The present invention provides for methods of producing a drug product that is capable of providing controlled and sustained release of a drug. Particularly, the release of the drug will be to a specific tissue area in the body. The methods include, but are not limited to, providing an impermeable casing with an open end, placing a compressed drug pellet into the impermeable casing, coating the open end of the impermeable casing with a permeable layer to create a release window for the drug product to provide controlled and/or sustained release of the drug.

  • Patent number: 9040071
    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.
