Abstract
A stimulation electrode assembly configured to be positioned relative to a patient for an operative procedure is disclosed. An evoked stimulation response may be sensed by a sensor near a portion of a subject. The evoked response may be sensed by an electrode and determined with a monitoring system.
Claims21
A method of monitoring a stimulation of a selected nerve, comprising:
- contacting a first stimulation electrode at a first location to a surface of an auricle of a subject;
- contacting a second ground electrode at a second location to a surface of the auricle of the subject;
- delivering an electrical current to the subject through at least the first stimulation electrode to the subject;
- positioning a receiving electrode near the selected nerve within the subject and spaced away from the auricle;
- and
- operating a control system having a processor for:
- receiving a signal related to the delivered current;
- and
- displaying a representation of the received signal with a display device;
- wherein the received signal is altered when the selected nerve is interrupted.

A method of monitoring a stimulation of a selected nerve, comprising:
- contacting a first stimulation electrode at the concha cymba of an auricle of a subject;
- contacting a second stimulation electrode at the concha cavum of the auricle of the subject;
- contacting a third stimulation electrode at the tragus of the auricle of the subject;
- contacting a fourth stimulation electrode at the anti-helix of the auricle of the subject;
- injecting a current into the subject through the first, second, third and fourth electrodes to stimulate the selected nerve;
- receiving a signal related to the delivered current from the selected nerve at a sensor positioned adjacent the selected nerve and spaced away from the auricle;
- and
- displaying a representation of the received signal with a display device.
5 more elements
A system configured for monitoring a stimulation of a selected nerve, comprising:
- a stimulator configured to be positioned at a first location on a surface of an auricle of a subject, the stimulator includes a plurality of electrodes configured to be positioned at a plurality of spaced apart locations on the auricle, the plurality of electrodes including at least one stimulation electrode configured to be positioned at a first location on the auricle and a ground electrode configured to be positioned at a second location on the auricle;
- a sensor configured to be positioned at a third location relative to the subject and spaced away from the auricle;
- a display device;
- and
- a controller configured to:
- generate an electrical signal to be delivered to the subject through at least the stimulator,
- receive a signal related to the generated and delivered signal with the sensor;
- and
- generate a representation of the received signal for display with the display device;
- wherein the received signal is altered when the selected nerve is interrupted.
