  • Publication number: 20230397875
    Abstract: A system and method for modeling patient-specific spinal cord stimulation (SCS) is disclosed. The system and method acquire impedance and evoked compound action potential (ECAP) signals from a lead positioned proximate to a spinal cord (SC). The lead includes at least one electrode. The system and method determine a patient-specific anatomical model based on the impedance and ECAP signals, and transform a dorsal column (DC) map template based on a DC boundary of the patient-specific anatomical model. Further, the system and method map the transformed DC map template to the patient-specific anatomical model. The system and method may also include the algorithms to solve extracellular and intracellular domain electrical fields and propagation along neurons. The system and method may also include the user interfaces to collect patient responses and compare with the patient-specific anatomical model as well as using the patient-specific anatomical model for guiding SCS programming.

  • Publication number: 20230201592
    Abstract: A computer implemented method and system is provided for managing neural stimulation therapy. The method comprises under control of one or more processors configured with program instructions. The method delivers a series of candidate stimulation waveforms having varied stimulation intensities to at least one electrode located proximate to nervous tissue of interest. A parameter defines the candidate stimulation waveforms is changed to vary the stimulation intensity. The method identifies a first candidate stimulation waveform that induces a paresthesia-abatement effect, while continuing to induce a select analgesic effect. The method further identifies a second candidate stimulation waveform that does not induce the select analgesic effect. The method sets a stimulation therapy based on the first and second candidate stimulation waveforms.

  • Publication number: 20230148739
    Abstract: Apparatus and associated methods relate to a fibrillous abrasive crevice cleaner (FACC). In an illustrative example, a fibrillous abrasive tip may be made of a continuous combination of steel wool and wire. For example, the FACC may include a twisted multistrand handle extending from a distal end to a proximal end along a longitudinal axis. The FACC may include a continuous fibrillous mass fixedly coupled about the distal end of the twisted multistrand handle, such that the fibrillous mass forms a knot distal to the proximal end of the twisted multistrand handle. For example, the FACC may include a proximal end of the fibrillous mass captured between the twisted multistrand handle. The formed knot around the distal end of the twisted multistranded handle and the fibrillous mass being entwined into the handle may, for example, advantageously resist decoupling of the fibrillous mass from the twisted multistrand handle.
