Abstract

An implantable subcutaneous electrode system is disclosed. The implantable subcutaneous electrode system may include an electrode body with electrical contacts disposed thereon or integrally formed therein. The electrode body also may include an insulation region defined between the electrical contacts and an aperture defined in the electrode body for receiving an anchoring device. A minimally invasive delivery device and methods for delivery of an implantable electrode system is also provided. The methods may include steps of introducing a needle comprising a cannula and a stylet through a patient's skin, removing the stylet while leaving the cannula in place, introducing an electrode applicator through the cannula, the electrode applicator comprising a hollow driver which receives the electrode assembly, and anchoring the electrode assembly to a bone by driving the hollow driver such that a self-tapping screw within the electrode assembly screws into the bone.
