System and method for neurostimulation

A brain stimulation method and system are provided, wherein neuronal signals of a patient are continuously sensed by at least one sensor device and based on the sensed signals, stimulation signals are applied to the patient by at least one stimulation device, wherein the sensed signals are transmitted to a body-external, portable processing device wherein the sensed signals are evaluated, and based on the evaluated signals stimulation control signals are generated and transmitted to the stimulation device where based on the stimulation control signals the stimulation signals are generated.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/021, A61B5/0531, A61B5/11, A61B5/24, A61B5/398). The claims define what a patent protects, and they are not read here.

Packaging

Body fluid destroys unprotected electronics. An implant meant to last has to stay sealed for years while passing every channel through its wall. The problem behind it: a seal that lasts as long as the patient needs it, at a size that leaves room for the channels.

Telemetry

Thousands of channels produce more data than a low-power radio can carry raw, so what is sent, and how, decides what the system can use. The problem behind it: high data rates at low power through tissue, reliably and securely.

Stimulation

Restoring sensation, sight or movement needs information going in, and a therapy that adapts needs to sense and stimulate at once. The problem behind it: evoking a precise, stable effect without damaging tissue or electrodes, and without blinding the recording.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
