The NVM5®g System is a medical device that is intended for intraoiperative neurophysiologic monitoring during spinal surgery. The device provides information directly to the surgeon, to help assess a patient's neurophysiologic status. NVM5 provides this information by electrically stimulating nerves via electrodes located on surgical accessories and monitoring electromyography (EMG), transcranial or lumbar motor evoked potential (MEP), or somnatosensory evoked potential (SSEP) responses of nerves. The System also integrates BendiniQ software used to locate spinal implant instrumentation for the placement of spinal rods.
* XLIF (Detection) - The XLIF (Detection) function allows the surgeon to locate and evaluate spinal nerves, and is used as a nerve avoidance tool.
* Basic & Dynamic Screw Test - The Screw Test functions allow the surgeon to locate and evaluate spinal nerves by providing proximity information before, during or after bone preparation and placement of bone screws.
* Free Run EMO - The Free Run EMG function identifies spontaneous EMO activity of spinal nerves by continually displaying a live stream waveform of any myotomne contractions.
* Twitch Test (Train of Four) - The Twitch Test Function allows the surgeon to assess moderate degrees of neuromuscular block in effect by evaluating muscle contraction following a train of four stimulation pulses.
* MEP -Transcranial or lumbar (i.e., conus in region of LI-L2) stimulation techniques for motor evoked potentials are used to assess for acute dysfurnction in axonal conduction of the corticospinal tract and peripheral nerves. The MEP function provides an adjunctive method to allow the surgeon to monitor spinal cord and motor pathway integrity during procedures with a risk of surgically induced motor injury.
- SSEP - The SSEP function allows the surgeon to assess sensory spinal cord function in surgical procedures during which the spinal cord is at risk.
* Remote Reader - The Remote Reader function provides real time remote access to the NVM5 System for a monitoring physician outside of the operating room.
* Guidance - The Guidance function is intended as an aid for use in either open or percutaneous pedicle cannulation procedures in the lumbar and sacral spine (Li-SI) of adult patients, and when used in conjunction with radiographic imaging and EMG, allows the surgeon to assess the angulation of system accessories relative to patient spinal anatomy for the creation of a cannulation trajectory for bone screw placement.
- Bendini - The Bendini Spinal Rod Bending function is used to locate spinal implant system instrumentation (screws, hooks) to determine their relative location to one another to generate bend instructions to shape a spinal rod. A surgeon is able to use those instructions and bend a rod using the Bendini Bender, a mechanical rod bender.
