Abstract

A surgically implantable reservoir is provided for implantation into a patient for use in an iontophoresis system. The reservoir and system are used for local drug delivery through a target site of internal or external body tissue. The iontophoresis system includes a source electrode and a counter electrode in electrical communication with the source electrode for forming a localized electric field at the target site. A fluid cargo may comprise a drug solution to be delivered to target tissue. For example, a chemotherapeutic drug solution or any other fluid polar substance may be delivered via the reservoir. In one embodiment, the fluid cargo may include ribonucleic acid molecules.
