Neural-interface probe and methods of packaging the same

A neural-interface probe is provided. The probe may comprise a chip, a wire bundle substrate, and an encapsulant material. The chip may comprise a plurality of bond pads. The wire bundle substrate may comprise a plurality of wires extending through the substrate. The plurality of wires may comprise: (1) a proximal portion connected to the plurality of bond pads to thereby couple the chip to the substrate, and (2) a flexible distal portion configured to interface with neural matter. The encapsulant material may be disposed at least between the chip and the wire bundle substrate.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B2560/0276, A61B2562/0209, A61B2562/125, A61B5/294, A61B5/4064). 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.

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.

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.
