Abstract
An implantable externally driven fluid delivery system for localized delivery of medical agents and drugs, such as antibiotics, may be provided herein. The fluid delivery system includes a housing that incorporates a filling septum connected to a flexible internal reservoir. The reservoir is connected to a miniature diaphragm pump with coupled magnetic components. The entire fluid delivery system is implantable into a body cavity or surgically formed location that provides for local medical agent delivery. The reservoir is filled via percutaneous injection through the skin into the septum. Fluid delivery is achieved through proximity of the external controller that generates an oscillating or reversing magnetic field suitable to actuate the pump's diaphragm resulting in controlled fluid flow. Once local drug delivery treatment is complete, the controller can be discarded.
