Neural interface with edge protected porous material

The invention relates to a system (100) for peripheral nerve stimulation, in particular for the detection and/or monitoring of neuronal and/or muscle activity, comprising at least one nerve stimulation device (110) wherein the nerve stimulation device (110) comprises at least a first recording means (130) and a second recording means (140), wherein the first recording member (130) and the second recording member (140) are configured to be arranged at a recording member distance (120) from each other and to detect a stimulus propagating along a neural structure, in particular along an efferent and/or afferent nerve, respectively, such that a velocity of the stimulus propagating along the neural structure can be determined.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/263, A61B5/293, A61B5/294, A61B5/311, A61B5/388). 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.
