Flexible neural electrode assembly

The present application provides a flexible neural electrode assembly which includes a flexible electrode, a traction member, an auxiliary fixing assembly, and an elastic sealing member. The flexible electrode includes a proximal contact portion, a lead connection portion, a distal electrode portion, and an auxiliary implantation portion. The flexible electrode and traction member both penetrate through the auxiliary fixing assembly for implantation into the target tissue. The elastic sealing member is sleeved outside the flexible electrode and the traction member and configured to abut against the auxiliary fixing assembly at least after the distal electrode portion is implanted into the target tissue to a preset depth, and to deform under the action of the auxiliary fixing assembly to compress the flexible electrode, such that the distal electrode portion of the flexible electrode is fixed at the preset depth, and the flexible electrode is sealingly connected to the auxiliary fixing assembly via the elastic sealing member.

  Packaging and hermeticity

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2562/0209, A61B5/263, A61B5/294, A61N1/05, A61N1/0539). 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.

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.
