Implantable neurostimulation systems
First Claim
1. An implantable neurostimulator comprising:
- a housing;
mounting means for securing the housing and the neurostimulator to a cranium of a patient;
stimulus generating means provided within the housing for generating a therapeutic electrical stimulus;
an electrode for contacting a dura of a brain of the patient;
biasing means arranged between the mounting means and the electrode for biasing the electrode toward the brain of the patient and moving the electrode independent of the housing;
a wire electrically connecting the pulse generating means and the electrode wherein the pulse generating means is housed in the housing mounted to the patient'"'"'s cranium and the electrode is biased against the patient'"'"'s brain via the biasing means, the wire adapted and configured to deliver the electrical stimulus generated by the pulse generating means to the electrode; and
a stem element extending integrally from the housing and arranged between the housing and the electrode, a length of the stem setting a minimum distance between the housing and the electrode.

Abstract
New and useful neurostimulation systems are provided that include an implantable pulse generator dimensioned and configured for implantation in the skull of a patient. The implantable pulse generator has an electrode operatively associated with a distal end portion thereof and can be provided with adjustment means, such as an adjustable biasing member or spring arranged between the electrode to the distal end portion of the pulse generator. Also provided are systems involving networked neurostimulators that are configured and adapted to work jointly in accordance with prescribed treatment protocol to effect a desired recovery from brain injury. Such networked neurostimulation systems are particularly advantageous for effecting relatively large and/or relatively distant regions of the brain. Additionally, systems and methods for motor-evoked potential (MEP)-based neuromodulation are provided. Further, AC and/or DC stimulation can be utilized, depending on the precise implementation.
