  • Patent number: 11173308
    Abstract: Techniques for determining the trajectory of a one or more dorsal roots and utilizing the trajectories to improve a spinal cord stimulation model are disclosed. A first improvement constructs a target stimulation field along a path that is parallel with the determined trajectory that is nearest to a specified desired location of stimulation. An allocation of stimulation among the electrodes to mimic the target field is computed. A second improvement models a response of neural elements at evaluation positions that are parallel with the trajectories based on the electric field that is generated for the computed allocation of stimulation among the electrodes. The stimulation amplitude is adjusted based on the neural element modeling to maintain stimulation intensity, and the stimulation amplitude and allocation of stimulation among the electrodes are compiled into an electrode configuration that is communicated to a neurostimulator.

  • Patent number: 11160509
    Abstract: The exemplified technology facilitates de-noising of magnetic field-sensed signal data (e.g., of an electrophysiological event) using signal reconstruction processes that fuse the magnetic field-sensed signal data with another sensed signal data (e.g., voltage gradient signal data) captured simultaneously with the magnetic field-sensed signal data. To this end, the purely algorithmic processing technique beneficially facilitates removal and/or filtering of noise from a sensor lead of a noisy captured source and rebuilds the signal for that lead from information simultaneously obtained from other leads of a different source. In some embodiments, a data are fused via a sparse approximation operation that uses candidate terms based on Van der Pol differential equations.
