Publication number: 20250128062Abstract: System for effecting a reversible sensory block includes a hybrid neuromodulator and hybrid lead for delivering electrical and pharmacological stimulation. An implantable modulator provides electrical pulse generation and pharmacological fluid infusion. Method for effecting a reversible sensory block delivers low-frequency stimulation based on the conduction velocity of a target afferent. Afferents with different conduction velocities may be blocked by stimulation with different frequencies. Temporally synchronized pulse stimuli from multiple stimulating electrodes may interfere with each other to stimulate a specific afferent. Spatial summation of synchronized low-frequency pulse stimulation may be delivered at multi-sites. Temporal interference of two kilohertz sinusoidal stimuli with slight frequency difference deliver a low-frequency sinusoidal stimulus at a focal region of interference. Spatial summation translates to evoked action potentials that converge at T-junction of a targeted afferent.Type: ApplicationFiled: October 23, 2024Publication date: April 24, 2025Applicant: University of ConnecticutInventors: Bin Feng, Longtu Chen, Jia Liu, Shaopeng Zhang
