First Claim
Patent Images
1. An implantable device comprising:
- a stimulation generator that generates electrical stimulation to treat at least one of pain or tension in at least one of a head, neck or facial region of a patient;
a battery within the housing that powers the stimulation generator;
a set of electrodes, coupled to the stimulation generator, that delivers the electrical stimulation; and
a device housing that houses the stimulation generator and the battery, wherein the device housing is sized and shaped to fit within and at least partially conform to a subcutaneous region within a back of the neck of the patient when the device housing is implanted in the subcutaneous region, andwherein the electrodes are arranged in a two-dimensional array on a surface of the housing.

Abstract
The disclosure describes an implantable neurostimulator device for delivery of neurostimulation to treat head, neck, or facial pain or tension, including pain or tension caused by occipital neuralgia. The device may be a neurostimulation device having a miniaturized housing with a low profile that permits subcutaneous implantation at a stimulation site directly adjacent a neuralgic region at the back of the neck of a patient. For example, the device may be subcutaneously implanted at the back of the neck of a patient to relieve symptoms of occipital neuralgia.
