The invention comprises an elongated device adapted for insertion including self-insertion through the body especially the skull. The device has at least one effector or sensor and is configured to permit implantation of multiple functional components through a single entry site into the skull by directing the components at different angles. The device may be used to provide electrical magnetic and other stimulation therapy to a patient"s brain. The lengths of the effectors sensors and other components may completely traverse skull thickness (at a diagonal angle) to barely protrude through to the brain"s cortex. The components may directly contact the brain"s cortex but from there their signals can be directed to targets deeper within the brain. Effector lengths are directly proportional to their battery size and ability to store charge. Therefore longer angled electrode effectors not limited by skull thickness permit longer-lasting batteries which expand treatment options.
