Abstract
This invention discloses bioerodible devices, such as implants for delivering therapeutic agents, particularly large molecules such as proteins and antibodies, in a controlled manner. The devices comprise a porous silicon-based carrier material impregnated with the therapeutic agent. The device may be used in vitro or in vivo to deliver the therapeutic agent, preferably in a controlled fashion over an intended period of time such as over multiple days, weeks or months. The device may be used for treating or preventing conditions of a patient such as chronic diseases.
