Intended Use

The FHC microTargeting® Electrode is intended for use in intra-operative recording of single unit neuronal activity or intra-operative stimulation of neural elements in the brain.

Device Story

The microTargeting® Electrode is a depth electrode used during functional neurosurgery. It functions as an input device for intra-operative single unit neuronal activity recording and as an output device for neural stimulation. The device consists of electrodes and a protective tube, with an optional sterilization tray. It is operated by a neurosurgeon in an intra-operative setting. The recorded signals are processed by external systems to assist the surgeon in identifying neural targets within the brain. By providing real-time electrophysiological feedback, the device aids in precise electrode placement, potentially improving surgical outcomes and reducing risks associated with functional neurosurgical procedures.

Clinical Evidence

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

Technological Characteristics

Depth electrode for intra-operative neural recording and stimulation. Components include electrodes and a protective tube. Device is a passive electrical conductor used in conjunction with external recording/stimulation systems. No active software or internal power source.

Indications for Use

Indicated for patients undergoing functional neurosurgery requiring intra-operative recording of single unit neuronal activity or stimulation of neural elements in the brain.

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 Mr. Haer:

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.
