US Patent 9,014,798

Automated Stimulus Artifact Removal for Nerve Conduction Studies

Issued: April 21, 2015 Inventors: Tracey, Brian et al. Current Owner: Impulse Medical Technologies, Inc. and Alera MedTech Original Assignee: NeuroMetrix, Inc.

A method for the automated removal of a stimulus artifact from an electrophysiological signal waveform. The novel method comprises providing a model of the stimulus artifact that is physically derived and based on known properties of the electrophysiological signal waveform acquisition hardware and stimulator, and filtering the stimulus artifact out of the electrophysiological signal waveform using the model.

Apparatus and Method for Stimulator On-Skin Short Detection

Issued: June 26, 2018 Inventors: Boettcher, Bonniejean et al. Current Owner: Impulse Medical Technologies, Inc. and Alera MedTech Original Assignee: NeuroMetrix, Inc.

The invention relates to apparatus and methods for stimulating living tissues to determine nerve conduction properties. The invention overcomes the problem of reporting potentially inaccurate nerve conduction results by detecting a stimulator probe short or shunt condition during nerve conduction tests, accomplished by monitoring the magnitude of stimulus artifact waveform and voltage difference between stimulator probes.
