Implantable Neurostimulator with Integral Hermetic Electronic Enclosure, Circuit Substrate, Monolithic Feed-Through, Lead Assembly and Anchoring Mechanism

Abstract

An implantable medical device is provided for the suppression or prevention of pain, movement disorders, epilepsy, cerebrovascular diseases, autoimmune diseases, sleep disorders, autonomic disorders, abnormal metabolic states, disorders of the muscular system, and neuropsychiatric disorders in a patient. The implantable medical device can be a neurostimulator configured to be implanted on or near a cranial nerve to treat headache or other neurological disorders. One aspect of the implantable medical device is that it includes an electronics enclosure, a substrate integral to the electronics enclosure, and a monolithic feed-through integral to the electronics enclosure and the substrate. In some embodiments, the implantable medical device can include a fixation apparatus for attaching the device to a patient.

What is claimed is: 
     
         1 . An implantable stimulator configured for delivery of electrical stimulation to a nerve, comprising:
 a housing;   an electronics enclosure disposed on or in the housing; and   a stimulation lead coupled to the electronics enclosure, the stimulation lead including a malleable wire configured give the stimulation lead rigidity to penetrate tissue and malleability to conform to a target anatomy.   
     
     
         2 . The implantable stimulator of  claim 1  further comprising an attachment plate coupled to the housing, the attachment plate configured to accept a bone screw for attachment to bone.
