Conformal electrode arrays for electrophysiologic recording and neural stimulation within the cerebral ventricles and cerebral vasculature

The present disclosure relates to an array of electrodes and integrated electronics on a flexible scaffolding, with the ability to collapse into an axial configuration suitable for deploying through a narrow cylindrical channel. The electrode arrays can be placed into the ventricular system of the brain, blood vessels of the brain, and/or into other body cavities, constituting a minimally invasive platform for precise spatial and temporal localization of electrical activity within the brain and/or body, and precise electrical stimulation of tissue, to diagnose and restore function in conditions caused by abnormal electrical activity in the brain, nervous system, and/or elsewhere in the body.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2562/046, A61B2562/164, A61B5/282, A61B5/29, A61B5/293). 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.

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.

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.
