• Device Class: Class 2

Intended Use

The Magnes®3600 WH MEG is intended for use in diagnostic procedures that require the measurement and display of extracranial magnetic fields and information about the electrical activity in the brain as inferred from those fields.

Device Story

Magnes® 3600 WH MEG is a biomagnetometer designed to detect and measure magnetic fields generated by human brain electrical activity. The device utilizes magnetic sensors to capture these extracranial fields; transforms raw magnetic data into visual displays for clinical interpretation. Used in conventional medical facility environments; operated by trained personnel. Output allows physicians to visualize and analyze brain electrical activity to assist in diagnostic decision-making. Benefits include non-invasive assessment of neurological function.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Biomagnetometer system; magnetic sensor array for detecting extracranial magnetic fields; designed for conventional medical facility environments. Software-based display of measured magnetic fields and inferred electrical activity.

Indications for Use

Indicated for diagnostic procedures requiring measurement and display of extracranial magnetic fields and inferred brain electrical activity. No specific patient population, age, or contraindications provided.

Regulatory Classification

Identification

An electroencephalograph is a device used to measure and record the electrical activity of the patient's brain obtained by placing two or more electrodes on the head.

Dear Mr. Hirschkoff:

This letter corrects our substantially equivalent letter of December 3, 1999.

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
