What it concerns

The present invention relates to a neurostimulation system (100), in particular for Cortical and/or Deep Brain Stimulation, comprising:- at least one implant unit (110) comprising:- at least one first antenna (112), and- at least one lead (114) having at least one electrode array with at least one electrode; and- at least one wearable device (130) comprising at least one second antenna,wherein the at least one wearable device (130) is configured to wirelessly control and wirelessly communicate with the at least one implant unit (110), and wherein the at least one electrode is made of reduced graphene oxide, preferably hydrothermally reduced graphene oxide.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/291, A61B5/369, A61B5/4064, A61B5/4094, A61B5/4836). The claims define what a patent protects, and they are not read here.

Why it matters

Interface and electrodes
Everything downstream works with what the contacts pick up. Their number, size and distance from the neurons set the ceiling on the signal. The problem behind it: more contacts, closer to neurons, that still record after years in tissue that reacts to them.
Implant electronics
An implant has room for very little, so functions that fill a rack in the laboratory have to fit on a chip. The problem behind it: fitting channel count, computing and safety functions into a volume and a heat budget the body accepts.
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.

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.
