Publication number: 20230309886Abstract: A method of surgically positioning an electrode array at a desired implantation location relative to a nerve. A temporary probe electrode is temporarily positioned adjacent to the nerve and at a location which is caudorostrally separate to the desired implantation location of the electrode array. The implanted position of the probe electrode is temporarily fixed relative to the nerve. During implantation of the electrode array, electrical stimuli are applied from one of the temporarily fixed probe electrode and the electrode array, to evoke compound action potentials on the nerve. Compound action potentials evoked by the stimuli are sensed from at least one electrode of the other of the temporarily fixed probe electrode and the electrode array. From the sensed compound action potentials a position of the electrode array relative to the nerve is determined.Type: ApplicationFiled: June 6, 2023Publication date: October 5, 2023Applicant: Saluda Medical Pty LtdInventors: John Louis Parker, Milan Obradovic

Publication number: 20230241397Abstract: A method of applying a neural stimulus with an implanted electrode array involves applying a sequence of stimuli configured to yield a therapeutic effect while suppressing psychophysical side effects. The stimuli sequence is configured such that a first stimulus recruits a portion of the fibre population, and a second stimulus is delivered within the refractory period following the first stimulus and the second stimulus being configured to recruit a further portion of the fibre population. Using an electrode array and suitable relative timing of the stimuli, ascending or descending volleys of evoked responses can be selectively synchronised or desynchronised to give directional control over responses evoked.Type: ApplicationFiled: December 7, 2022Publication date: August 3, 2023Inventors: John Louis Parker, James Hamilton Wah, Dean Michael Karantonis, Milan Obradovic, Robert Bruce Gorman

Publication number: 20230096151Abstract: Disclosed is an implantable device for lead offset determination, comprising first and second electrode leads. A stimulus is delivered from one lead to tissue, and a signal is sensed from the tissue by the other lead. The sensed signal is processed to produce a measure of a stimulus artefact present in the signal. The stimulus artefact measure is used to produce a measure of an offset between the first electrode lead and the second electrode lead, such as by applying a distance-squared. analytical model to measures of stimulus artefact obtained from at least two sense electrodes. And/or, a compound action potential evoked by the stimulus is sensed from neural tissue, a latency of the evoked compound action potential is measured, and a measure of an offset between the first electrode lead and the second electrode lead is produced from the latency.Type: ApplicationFiled: September 28, 2022Publication date: March 30, 2023Applicant: Saluda Medical Pty LimitedInventors: Dean Michael Karantonis, Robert Bruce Gorman, Matthew Marlon Williams, Samuel Nicholas Gilbert, Milan Obradovic

Publication number: 20220249009Abstract: Automated assessment of neural response recordings involves storing a set of basis functions comprising at least one compound action potential basis function and at least one artefact basis function. Neural recordings of electrical activity in neural tissue are obtained by application of stimuli, using a single configuration of stimulation and recording. Each neural recording is decomposed by determining at least one parameter which estimates at least one of a compound action potential and an artefact. The at least one parameter is/are determined for each respective one of the plurality of neural recordings, to yield a plurality of values. A spread of the plurality of values is determined. An indication that the neural response recordings are of higher quality is output if the spread is small. An indication that the neural response recordings are of lower quality is output if the spread is large.Type: ApplicationFiled: July 13, 2020Publication date: August 11, 2022Applicant: Saluda Medical Pty LtdInventors: Daniel Parker, Milan Obradovic, Dean Karantonis, Ivan Guelton, Stephanie Ascone, Michael Narayanan

Publication number: 20210379383Abstract: This disclosure relates to implantable neuro stimulation devices with a feedback loop to control an amount of energy delivered into a neural tissue based on a measured evoked neural response. Stimulation electrodes deliver stimulation energy to neural tissue. A microprocessor performs closed-loop control of the stimulation energy based on a feedback signal that is indicative of an evoked neural response. A supervisor is connected to the feedback signal and detects malfunction of the stimulator based on the feedback signal. The supervisor is also connected to the stimulator to provide a status signal to the stimulator and changes the status signal to indicate malfunction upon detecting malfunction based on the feedback signal. The microprocessor adjusts the control of the stimulation energy in response to the status signal from the supervisor indicating malfunction.Type: ApplicationFiled: October 23, 2019Publication date: December 9, 2021Inventors: Peter SINGLE, Dean KARANTONIS, Robert GORMAN, Milan OBRADOVIC, Ivan GUELTON, Michael NARAYANAN

Publication number: 20210267518Abstract: A method is provided for processing a neural measurement obtained in the presence of noise, in order to detect whether a locally evoked neural response is present in the neural measurement. A first neural measurement is obtained from a first sense electrode. A second neural measurement is contemporaneously obtained from a second sense electrode spaced apart from the first electrode along a neural pathway of the neural response. A neural response decay is determined, being a measure of the decay in the neural response from the first sense electrode to the second sense electrode. A ratio of the neural response decay to an amplitude normalising term is calculated. From the ratio it is determined whether a locally evoked neural response is present in the neural measurement.Type: ApplicationFiled: April 6, 2021Publication date: September 2, 2021Applicant: Saluda Medical Pty LtdInventors: John Louis Parker, Milan Obradovic
