Intended Use
The NVM5® System is a medical device that is intended for intraoperative neurophysiologic monitoring during spinal surgery. The device provides information directly to the surgeon, to help assess a patient's neurophysiologic status. NVMS 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 somatosensory evoked potential (SSEP) responses of nerves. The System also integrates Bendini® 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 EMG - The Free Run EMG function identifies spontaneous EMG activity of spinal nerves by continually displaying a live stream waveform of any mechanically induced myotome 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 L1-L2) stimulation techniques for motor evoked potentials are used to assess for acute dysfunction in axonal conduction of the corticospinal tract and peripheral nerves. The MEP function provides an adjunctive method to allow the surgeon to 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 NVMS 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.
Device Description
The NVM5 System is a medical device that is intended for intraoperative 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), motor evoked potential (MEP) or somatosensory evoked potential (SSEP) responses of nerves. Moreover, a Twitch Test function is utilized to test the ability of the nerve to respond, or contract, following four stimulation pulses to determine the presence of neuromuscular block. Additionally, the NVM5 System includes an integrated stereotactic guidance system (NVM5 Guidance) to support the delivery of pedicle screws during EMG monitoring. The System also integrates Bendini® software used to locate spinal implant instrumentation for the placement of spinal rods. Lastly, the system also offers an optional screen sharing application to allow a secondary physician to remotely view the events represented on the NVM5 user interface. In summary, the NVM5 System includes the following six (6) software functionalities / modalities: - 1. Electromyography (EMG) - 2. Motor Evoked Potential (MEP) - 3. Somatosensory Evoked Potential (SSEP) - 4. Remote Reader - 5. Guidance - 6.

More Information

Not Found

No
The summary describes standard neurophysiological monitoring techniques and a software function for locating instrumentation, with no mention of AI or ML algorithms for data analysis, interpretation, or guidance.

No.
Explanation: The device is described as a monitoring device that provides information to the surgeon to assess neurophysiologic status and aid in surgical procedures, rather than directly treating a disease or condition.

Yes

The device "provides information directly to the surgeon, to help assess a patient's neurophysiologic status" by monitoring various neurophysiologic responses like EMG, MEP, and SSEP, and also helps locate and evaluate spinal nerves, all of which are diagnostic functions.

No

The device description explicitly states that the NVM5 System hardware consists of a Patient Module (PM) and computer, as well as accompanying accessory components which consist of an assortment of disposable conductive probes, electrodes, and electrode leads. This indicates the device includes significant hardware components beyond just software.

Based on the provided information, the NVM5® System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
  • NVM5 System Function: The NVM5 System operates intraoperatively (during surgery) and directly interacts with the patient's nervous system through electrical stimulation and monitoring of physiological responses (EMG, MEP, SSEP). It provides real-time information about the patient's neurophysiologic status in vivo.
  • Lack of Specimen Analysis: The device does not analyze any specimens taken from the patient.

Therefore, the NVM5 System falls under the category of a medical device used for intraoperative monitoring, not an In Vitro Diagnostic device.

Indications for Use

510(k) Number (if known) K132694

Device Name NuVasive® NVM5 System

Indications for Use (Describe)

The NVM5® System is a medical device that is intended for intraoperative neurophysiologic monitoring during spinal surgery. The device provides information directly to the surgeon, to help assess a patient's neurophysiologic status. NVMS 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 somatosensory evoked potential (SSEP) responses of nerves. The System also integrates Bendini® 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 EMG - The Free Run EMG function identifies spontaneous EMG activity of spinal nerves by continually displaying a live stream waveform of any mechanically induced myotome 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 L1-L2) stimulation techniques for motor evoked potentials are used to assess for acute dysfunction in axonal conduction of the corticospinal tract and peripheral nerves. The MEP function provides an adjunctive method to allow the surgeon to 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 NVMS 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.
