Flexible electrode for spinal cord and method for manufacturing same

The present disclosure relates to a flexible electrode for spinal cord and a method for manufacturing the same. There is provided a flexible electrode for spinal cord that includes an attachment portion configured to be capable of being outside an epidural or intradural white matter and configured to acquire or apply an electrical signal on a surface of the spinal cord; wherein the attachment portion of the flexible electrode includes first and second insulating layers and a wire layer located therebetween; wherein the attachment portion of the flexible electrode further includes one or more electrode sites, each of which is electrically coupled to one of wires in the wire layer, and is in contact with the spinal cord after implantation of the flexible electrode to acquire or apply an electrical signal from or to a spinal nerve.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2562/0209, A61B2562/046, A61B2562/125, A61B2562/164, A61B2562/227). 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.

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.
