Electrical stimulation device for cortical evoked potential capable of acquiring electrical stimulation sequence on the basis of task

An electrical stimulation device for a cortical evoked potential capable of acquiring an electrical stimulation sequence on the basis of a task. Different channel sets related to a plurality of functions are constructed and sorted, that is, channels in any channel set that have not undergone electrical stimulation acquire alternative values of the channel sets on the basis of task-related electroencephalogram activation levels, and the alternative values corresponding to different channel sets are sorted to obtain a sequence of the channel sets; channels are sorted on the basis of the task-related electroencephalogram activation levels; and the order of the sorted channels is used as a preset electrical stimulation sequence for a cortical evoked potential. The device can characterize the relevance of channels across different functional areas, and can indicate the importance of the channels in the functional areas, such that a doctor is guided more objectively to obtain more useful electrical stimulation data within a shorter surgical time, so as to determine whether the positions of the channels affect functions and whether resection is allowed.

  Stimulation

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61B5/37, A61B5/383, A61B5/4094, A61B5/72). The claims define what a patent protects, and they are not read here.

Signal processing

A decoder is only as good as the features it is given, and recordings drift and pick up noise from movement, muscle and stimulation. The problem behind it: stable features from signals that change from day to day, computed fast enough to act on.

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.
