  • Publication number: 20250242159
    Abstract: A multi-modal method of stimulation to provide therapy for an epilepsy patient. A neuroprotective therapy including both an electrical modulation signal and an optical modulation signal is generated on a periodic or scheduled basis. The patient is monitored, and if a trigger condition arises indicating one of potential seizure onset, seizure onset, or an ongoing seizure, a symptom modulation therapy is initiated. The neuroprotective therapy and the symptom modulation therapy may have different targets and other parameters.

  • Publication number: 20250222260
    Abstract: Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which active electrodes are selected for the patient. This allows sweet spot searching to occur much more quickly and without the need to wash in the various electrode combinations that are tried. After selecting electrodes using supra-perception therapy, therapy is titrated to sub-perception levels using the selected electrodes. Such sub-perception therapy has been investigated using pulses at or below 10 kHz, and it has been determined that a statistically significant correlation exists between pulse width (PW) and frequency (F) in this frequency range at which SCS patients experience significant reduction in symptoms such as back pain.

  • Publication number: 20250114601
    Abstract: A system may be configured for treating a patient with epileptic seizures. The system may include a therapy delivery system configured to use a set of electrodes positioned adjacent to a spinal cord or dorsal column nuclei and a stimulation configuration to deliver neuromodulation energy to at least one target neural pathway in or near the spinal cord. The at least one target neural pathway includes the dorsal column nuclei or axons projecting to the dorsal column nuclei. The dorsal column nuclei and the axons are somatotopically organized and project to at least one of a cerebellum, a thalamus or a brainstem, which include somatotopically organized nuclei and project axons to different areas of a cortex. The at least one target neural pathway corresponds to at least one of the different areas of the cortex in which the epileptic seizures were located.

  • Publication number: 20250082938
    Abstract: Methods and systems for addressing issues related to synchrony in neural tissue signals. A spectrum of neural signals in a patient may be measured while the patient is asymptomatic, and compared to signals during a symptomatic episode to determine whether neural signals should be enhanced or disrupted. Depending on the change to neural signals, either enhancing or disrupting neural therapy is generated and confirmed or adjusted.
