A system comprises a support structure configured for placement on or about a subject's head and an electronic recording apparatus comprising an array of magnetic sensors mounted to the support structure. The array of magnetic sensors is configured for transcranial sensing of local magnetic fields emanating from a specified region of a subject's brain. The sensed local magnetic fields correspond to patterns of stimulation of the specified region of a subject's brain caused by stimulating one or more of a sensing organ or sensing organs, a vestibular system, and a memory of the subject. An electronic memory is configured to record neurostimulation data representative of the patterns of stimulation of the specified region of the subject's brain.

A diagnosis device, and more particularly, a compartment syndrome diagnostic device is described herein. The diagnostic device may include a display that renders information associated with stimulation of a motor unit suspected of suffering from compartment syndrome. The diagnostic device may generate a stimulation signal for stimulating the motor unit through an electrode. The device may determine whether the motor unit is at risk for compartment syndrome based on the response of the motor unit to the stimulation. The diagnostic device may also measure pressure of a compartment. The device may determine whether the motor unit is at risk for compartment syndrome based on the measured pressure and the response of the motor unit to the stimulation.

The present invention relates to endotracheal tubes for intra-operative monitoring of nerve and muscle tissue (neuromonitoring), a system for intra-operative neuromonitoring, a method for deriving stimulus responses in intra-operative neuromonitoring, and a method for classifying tissue types, having the purpose of preventing damage to nerves and muscles which run within the area of operation.

Methods and systems for obtaining and analyzing electromyography responses of electrodes of an implanted neurostimulation lead for use neurostimulation programming are provided herein. System setups for neural localization and/or programming include a clinician programmer coupleable with a temporary or permanent lead implantable in a patient and at least one pair of EMG sensing electrodes minimally invasively positioned on a skin surface or within the patient. The clinician programmer is configured to determine a plurality of recommended electrode configurations based on thresholds and EMG responses of the plurality of electrodes and rank the electrode configuration according to pre-determined criteria. The clinician programmer further includes graphical user interface on which the plurality of recommended electrode configurations are displayed for modification and/or selection by a clinician in programming an IPG or EPG coupled with the lead to apply a neurostimulation treatment according to the selected electrode configuration.

Systems and methods for treating a patient having symptoms of restless legs syndrome (RLS) or Periodic Limb Movement Disorder (PLMD) using high-frequency stimulation by applying a high-frequency pulsed electrostimulation therapy signal to a femoral nerve or a branch thereof. An electrostimulation device can include or use clonus detection circuitry can be used such as to monitor for a presence of clonic activity during treatment. Feedback from the clonus detection circuitry can be used to select or modify a therapy parameter of the electrostimulation device such as to help mitigate clonic muscle activity during therapy.

A surgical access system including a tissue distraction assembly 40 and a tissue retraction assembly 10, both of which may be equipped with one or more. electrodes 23 for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor 15 to a surgical target site. The tissue retraction assembly 10 has a plurality of blades 12, 16, 18 which may be introduced while in a closed configuration, after which point they may be opened to create an operation corridor 15 to the surgical target site, including pivoting at least one blade 12, 16, 18 to expand the operative corridor 15 adjacent to the operative site.

A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.
