Device Facts

• Record ID: K020903
• Device Name: DOCXS B SERIES ELECTRODES
• Applicant: Docxs, LLC
• Product Code: GXY · Neurology
• Decision Date: Sep 26, 2002
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 882.1320
• Device Class: Class 2

Indications for Use

Biopotential skin electrodes will be used by the Bio Medical community in both clinical and research applications of the acquisition of all surface biopotentials, standards, and reference, i.e. Electroencephalograph (EEG), Electrocardiograph (ECG), Electromyography (EMG), Electrooculograph (EOG).

Device Story

DocXS B series electrodes are sintered Ag-AgCl electrodes with 99.99% silver wire. Some models are bare; others are housed in epoxy or silicone with PVC, silicone, or TPE-insulated tinned copper lead wires. Electrodes feature a recessed underside for electroconductive gel application to improve signal conductivity. Lead wires terminate in DIN safety sockets, snaps, or pinch connectors. Used by clinicians and researchers to acquire surface biopotentials (EEG, ECG, EMG, EOG). The device provides a stable interface between the subject's skin and monitoring equipment, facilitating accurate biopotential measurement.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Sintered Ag-AgCl electrode; 99.99% silver wire; epoxy or silicone housing; PVC/silicone/TPE insulated tinned copper lead wires; DIN safety socket, snap, or pinch connectors. Non-porous, waterproof, cold-sterilizable finish. Passive sensing device.

Indications for Use

Indicated for clinical and research acquisition of surface biopotentials including EEG, ECG, EMG, and EOG in patients requiring such monitoring.

Regulatory Classification

Identification

A cutaneous electrode is an electrode that is applied directly to a patient's skin either to record physiological signals (e.g., the electroencephalogram) or to apply electrical stimulation.

# Description of Device

Product Description: Biopotential Electrodes, various types and models Proprietary Device name: B series electrodes Common\Generic Name: Biopotential electrodes, various types and models Trade Name: Cutaneous electrodes FDA Classification Name: Cutaneous electrodes Device Class: 2 Product Code: GXY Regulation Number: 882.1320 Medical Specialty/Panel: NEUROLOGY Manufacture of original device: NA Establishment Operations: manufacturer

This specific device is comprised of a sintered Ag-AgCl electrode with a 99.99% Silver wire. Some of the electrodes are to be sold as bare electrodes. Some are set and sealed in an epoxy or silicone housing with a PVC, Silicone or other TPE insulated, tinseled copper lead wire attached. The device is then sealed with either silicone or Epoxy. They have a smooth, non-porous finish on all surfaces with no cracks, seams, or bubbles. It is then considered waterproof and cold sterilizable. There is a recess in the underside of the housing surrounding the exposed electrode surface to allow for the placement of an electroconductive gel. The gel establishes contact between the Ag-AgCl electrode and the subject surface to be measured. The gel improves electro conductivity between the subject surface and the Ag-AgCl electrode surface for a more sensitive and accurate reading of the Biopotential.

The lead wires are either unterminated or terminate with a 1.5 DIN safety socket, snap, or pinch connector. Exasple . Je ctron

Dear Mr. Rizzolo:

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.
