Medical device for closed loop vagal nerve stimulation

This disclosure relates to medical implant systems and apparatuses capable of treating a seizure condition through the use of recording and stimulating electrodes. The apparatus includes an internal pulse generator in communication with a wireless communication module; one or more recording electrodes in communication with the internal pulse generator, wherein the one or more recording electrodes are configured to monitor to detect one or more field potentials produced by neural tissue in proximity to the one or more recording electrodes; one or more stimulating electrodes in communication with the internal pulse generator, wherein the one or more stimulating electrodes are configured to stimulate the vagus nerve.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61N1/025, A61N1/0529, A61N1/36053, A61N1/36064, A61N1/3614). The claims define what a patent protects, and they are not read here.

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.

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.
