Abstract
Implantable drug delivery systems target delivery of small volumes of drugs to specific tissues. In some cases, a drug delivery system includes an implantable osmotic pump connected to a drug-containing housing, with that housing connected to a needle, cochlear implant or other type of component for ultimate delivery to the target tissue. In some implementations, a subcutaneous port receives a fluid from an external pump. The port is connected to a needle or other component for delivery of one or more drugs to the target tissue. Both solid and liquid drug formulations can be used. In embodiments using solid drugs, a separate drug vehicle (such as saline) can be used to dissolve a portion of the solid drug, with the drug-loaded vehicle then delivered to the target tissue.
