Implantierbare Manschettenelektrode

Implantierbare Manschettenelektrode, aufweisend: eine flexible Manschette in Form eines Schlauches mit einem Längsschlitz, wobei der Längsschlitz eine erste Kante und eine zweite Kante an der Manschette definiert, wobei an der ersten Kante des Längsschlitzes eine erste Lippe angeordnet ist und an der zweiten Kante des Längsschlitzes eine zweite Lippe angeordnet ist, und wobei der Längsschlitz durch die erste Lippe und die zweite Lippe abdichtbar ist, indem die erste Lippen und die zweite Lippe zumindest teilweise auf dem Manschettenmantel der Manschette übereinander liegend verlaufen und die zweite Lippe die erste Lippe durch flächige Pressung auf dem Manschettenmantel in Position hält.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61N1/0556, A61N1/3605). 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.

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.
