Systems and methods for preventing noise in an electric waveform for neural stimulation, block, or sensing
12274882 · 2025-04-15 · ·

One aspect of the present disclosure relates to a system that can prevent unintended signal components (noise) in an electric waveform that can be used for at least one of neural stimulation, block, and/or sensing. The system can include a signal generator to generate a waveform that includes an intended electric waveform and unintended noise. The system can also include a signal transformer device (e.g., a very long wire) comprising a first coil and a second coil. The first coil can be coupled to the signal generator to receive the waveform and remove the unintended noise from the electric waveform. The second coil can pass the electric waveform to an electrode. The second coil can be coupled to a capacitor that can prevent the waveform from developing noise at an electrode/electrolyte interface between an electrode and a nerve.

PLEDGET STIMULATION AND RECORDING ELECTRODE ASSEMBLIES

Aspects of the disclosure relate to pledget stimulation/recording electrode assemblies that are particularly useful for automatic periodic stimulation. Embodiments are compatible with nerve monitoring systems to provide continuous stimulation of a nerve during surgery. Disclosed embodiments include an electrode assembly having one or more electrodes rotatably supported by and positioned within a pledget substrate. The flexible pledget substrate conforms and fixates to bioelectric tissue to secure the electrode assembly in position, wrapped around the target tissue. In some embodiments, the pledget substrate includes two bodies, each including at least one electrode, the two bodies being selectively separable so that the bodies can be repositioned with respect to one another. The electrode assembly further includes a lead wire assembly including at least one insulating jacket positioned around a wire core. Optionally, the electrode assembly includes an insulating cup interconnecting the electrode and the insulating jacket.

Neural Sensing in an Implantable Stimulator Device During Passive Charge Recovery

Techniques for sensing neural responses such as Evoked Compound Action Potentials (ECAPs) in an implantable stimulator device are disclosed. A first therapeutic pulse phase is followed by a charge recovery phase that includes at least one high-impedance passive charge recovery duration. The ECAP is sensed during the high-impedance passive charge recovery duration.

System and method for empirical assessment of nerve health during a spinal decompression procedure
12279879 · 2025-04-22 · ·

A method for assessing nerve health during a spinal decompression procedure includes: accessing a database containing historical patient data; receiving patient data of a target patient; identifying a subset of historical patients with similar pre-operative characteristics; generating an individualized target range for at least one nerve function parameter based on the subset; measuring an actual nerve function parameter of the target patient during the procedure; and displaying a graphical representation of the measured parameter relative to the individualized target range.

Catheter for cardiac and renal nerve sensing and mediation

A catheter is provided which exhibits higher resolution at its distal end. The higher resolution can be accomplished by combining and amplifying signals received at electrodes locally. These combined and amplified signals can then be digitized locally and transmitted for further processing. Optical communication channels may be used.
