Intended Use

The intended use of our µEEG™ Pro System 5000 is for temporary recording of intractanial neural activity, temporary intracranial stimulation of neurons, and mapping of neural activity and evoked potentials.

Device Story

µEEG™ Pro System 5000 performs intracranial neural activity recording and stimulation; maps neural activity and evoked potentials. Used in operating rooms during functional neurosurgery; operated by neurosurgeons/clinical staff. Inputs: intracranial depth or subdural electrode signals. Outputs: neurophysiological data for intraoperative monitoring. Assists surgeons in identifying neural targets and mapping brain function during procedures like epilepsy surgery or deep brain stimulation. Benefits: enables precise localization of neural activity to guide surgical intervention.

Technological Characteristics

Intracranial neurophysiological recording and stimulation system. Designed for operating room use. Includes warning labels regarding flammable anesthetics. Technical specifications and materials not detailed in provided documentation.

Indications for Use

Indicated for use during intracranial neurophysiological recording and stimulation during deep brain stimulation, epilepsy surgery, and other procedures where it is appropriate to perform intracranial depth or subdural electrode recordings.

Regulatory Classification

Identification

A depth electrode is an electrode used for temporary stimulation of, or recording electrical signals at, subsurface levels of the brain.

Dear Dr. Rogers:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
