• Applicant: Nuvasive, Inc.
• Product Code: GWF · Neurology
• Decision Date: Jan 24, 2007
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 882.1870
• Device Class: Class 2

Intended Use

The NeuroVision JJB System is used for intraoperative monitoring and neurological status assessment by the administration of brief electrical stimulus pulses to neural tissues and the EMG monitoring of the associated muscle groups. The System is used in conjunction with other NuVasive devices to assist in gaining controlled access to, and visualization of, the spine.

Device Story

NeuroVision JJB System provides intraoperative neurophysiologic monitoring during spine surgery; reduces risk of nerve root injury. System inputs: electrical stimulus pulses delivered to neural tissues; EMG signals captured from associated muscle groups via surface electrodes. System components: reusable Patient Module; Control Unit with embedded computer, touch screen, and interface card; various disposable/reusable conductive probes and leads. Operation: clinician delivers electrical pulses to neural tissues; system monitors resulting EMG responses in muscle groups. Output: real-time EMG monitoring data displayed on touch screen. Clinical utility: assists surgeons in gaining controlled access to and visualization of the spine; provides feedback on nerve status to guide surgical maneuvers and prevent nerve damage.

Clinical Evidence

No clinical data provided; substantial equivalence based on technological characteristics and intended use.

Technological Characteristics

System comprises a patient module, control unit with embedded computer, touch screen, and interface card. Uses conductive probes, electrodes, and leads for EMG monitoring and electrical nerve stimulation. Operates as an evoked response electrical stimulator (21 CFR 882.1870).

Indications for Use

Indicated for intraoperative monitoring and neurological status assessment via electrical stimulation of neural tissues and EMG monitoring of associated muscle groups during spine surgery to assist in gaining controlled access to and visualization of the spine.

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.

In accordance with Title 21 of the Code of Federal Regulations, Part 807, and in particular §807.92, the following summary of information is provided:

#### Submitted by: A.

Laetitia Cousin Director of Regulatory Affairs and Quality Assurance NuVasive, Incorporated 4545 Towne Centre Court San Diego, California 92121 Telephone: [phone] Fax: [phone]

#### B. Device Name

| Trade or Proprietary Name: | NuVasive NeuroVision JJB System |
|----------------------------|-------------------------------------------|
| Common or Usual Name: | Electromyography (EMG) monitor/stimulator |
| Classification Name: | Surgical nerve stimulator/locator |
| Device Class: | Class II |
| Classification: | $§$ 874.1820, $§$ 882.1870 |
| Product Code: | 77ETN, 84GWF |

#### C. Predicate Devices

The subject NeuroVision JJB System is substantially equivalent to the NeuroVision JJB System currently manufactured and distributed commercially in the U.S. by NuVasive.

#### D. Device Description

The NVJJB System utilizes conventional neurophysiologic monitoring to reduce the incidence of injury to nerve roots during instrumented spine surgery. In the procedure, stimulus evoked electromyography is used to determine changes in nerves. Corresponding muscle groups are monitored using surface electrodes, while stimulation is used to detect nerve responses.

The Neuro Vision JJB System consists of a reusable Patient Module, a Control Unit comprised of an embedded computer with touch screen controls and an interface card, and an assortment of disposable and reusable conductive probes, electrodes, and electrode leads.

{1}------------------------------------------------

#### Intended Use E.

The NeuroVision JJB System is used for intraoperative monitoring and neurological status The Neuro vision 952 byteen is as brief electrical stimulus pulses to neural tissues and the assessment by the associated muscle groups. The System is used in conjunction with other NuVasive devices to assist in gaining controlled access to, and visualization of, the spine.

### Comparison to Predicate Devices F.

The subject device has indications for use identical to those of its predicate, and employs the same principles of operation. Due to this equivalency, the device raises no new safety or effectiveness issues.

Dear Ms. Cousin:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
