Intended Use

The NeuroVision JJB System is intended to provide stimulation of spinal nerves during surgery of the spine, and assist, by administration of brief electrical stimulus pulses to tissues and nerves at the operative site, and EMG monitoring of muscle groups associated with those nerves, in the following: a) Location and evaluation of spinal nerves, using the System's Screw Test, Detection, and/or Free Run EMG Functions; and b) Location and identification of spinal nerves, using the System's Nerve Retraction Function. The NeuroVision JJB System is designed for use in conjunction with other NuVasive devices to assist in gaining controlled access to, and visualization of, the spinal nerve root, foramina, and surrounding tissues of the spine via uniportal or biportal approach, where anatomical restrictions safely permit.

Device Story

NeuroVision JJB System provides intraoperative neurophysiologic monitoring during spinal surgery. System inputs include electrical stimulus pulses delivered to tissues/nerves and EMG signals captured from muscle groups via electrodes. Device transforms these inputs to monitor nerve responses; functions include Screw Test, Detection, Free Run EMG, and Nerve Retraction. Output is displayed on a touch screen for the surgeon to assist in nerve identification and evaluation. Used in clinical settings by surgeons to gain controlled access to spinal nerve roots and surrounding tissues. Benefits include reduced risk of nerve injury during instrumented spine surgery.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

System includes reusable Patient Module, Control Unit with touch screen, interface card, and conductive probes/electrodes. Operates as an EMG monitor/stimulator. Software-based monitoring of spinal nerves.

Indications for Use

Indicated for patients undergoing spinal surgery requiring nerve surveillance, location, and identification of spinal nerves via EMG monitoring and electrical stimulation.

Regulatory Classification

Identification

An evoked response electrical stimulator is a device used to apply an electrical stimulus to a patient by means of skin electrodes for the purpose of measuring the evoked response.
