| 20110238036 | SUSTAINED RELEASE DELIVERY DEVICES - An injectable drug delivery device includes a core containing one or more drugs and one or more polymers. The core may be surrounded by one or more polymer outer layers (referred to herein as “coatings,” “skins,” or “outer layers”). In certain embodiments, the device is formed by extruding or otherwise preforming a polymeric skin for a drug core. The drug core may be co-extruded with the skin, or inserted into the skin after the skin has been extruded, and possibly cured. In other embodiments, the drug core may be coated with one or more polymer coatings. These techniques may be usefully applied to fabricate devices having a wide array of drug formulations and skins that can be selected to control the release rate profile and various other properties of the drugs in the drug core in a form suitable for injection using standard or non-standard gauge needles. | 09-29-2011 |
| 20100278931 | POROUS SILICON DRUG-ELUTING PARTICLES - The invention provides a biodegradable drug-eluting particle useful for the delivery of diagnostic or therapeutic agents. In certain embodiments, the drug-eluting particle of the invention comprises a biodegradable porous silicon body, a reservoir formed within the porous silicon body having at least one opening to an exterior of the body, wherein the reservoir contains a therapeutic or diagnostic agent, and an agent-permeable seal disposed over the at least one opening. The invention further provides a method for treating a patient to obtain a desired local or systemic physiological or pharmacological effect comprising administering a sustained release drug delivery particle of the invention. The invention also provides methods of fabricating a drug-eluting particle for releasing therapeutic agents | 11-04-2010 |
| 20100247607 | IMPLANTABLE FORMULATIONS OF BISPHOSPHONIC ACIDS - The invention relates to devices, methods and formulation for subcutaneous administration of a bisphosphonate. In such a device, a drug core, comprising a bisphosphonate, is disposed in a tube. The devices may be administered to a patient in need of subcutaneously wherein the release of the bisphosphonate is desired to provide sustained release of a therapeutically effective dose of the bisphosphonate. | 09-30-2010 |
