Concentric, Monopolar, Hook Wire and Hypodermic EMG Electrodes are intended for use with recording, monitoring and stimulation/recording equipment for the stimulation/recording of biopotential signals including electromyograph (EMG) and nerve potential signals.
EMG electrodes are applied in the study of biopotentials such as electromyograph (EMG), nerve conduction and stimulation/response. Electrodes are invasive as they are placed in contact with nerve or muscle tissue.
The electrodes consist of a needle with a connector/lead wire attached. The connector/lead wires terminate in a safety connector that cannot be connected to an AC power outlet.
The electrodes provide the patient contact device. The electrodes connect to the user's recording, monitoring and stimulation/response equipment. The electrodes are used under the supervision of a physician.
The EMG electrodes consist of a needle with a connector or lead wire attached. The connector or lead wires terminate in a safety connector that cannot be connected to an AC power outlet. The EMG Electrodes are provided sterile and for single patient use.
This document is a 510(k) summary for Sterile EMG Electrodes by Nicolet Biomedical Incorporated. It describes the device, its intended use, and its substantial equivalence to predicate devices. However, this document does not contain any information about acceptance criteria or a study proving device performance against such criteria.
Therefore, I cannot provide the requested information. The document focuses on demonstrating substantial equivalence to predicate devices, which is a regulatory pathway that typically does not involve new clinical performance studies or specific acceptance criteria for performance metrics like sensitivity, specificity, or accuracy.

1.0 Description of Electrodes
EMG electrodes are applied in the study of biopotentials such as electromyograph (EMG), nerve conduction and stimulation/response. Electrodes are invasive as they are placed in contact with nerve or muscle tissue.
The electrodes consist of a needle with a connector/lead wire attached. The connector/lead wires terminate in a safety connector that cannot be connected to an AC power outlet.
The electrodes provide the patient contact device. The electrodes connect to the user's recording, monitoring and stimulation/response equipment. The electrodes are used under the supervision of a physician.
2.0 Intended Use of Electrodes
EMG electrodes are intended for use with recording, monitoring and stimulation/recording equipment for the stimulation/recording of biopotential signals including electromyograph (EMG) and nerve potential signals.
3.0 Technological Characteristics
The EMG electrodes consist of a needle with a connector or lead wire attached. The connector or lead wires terminate in a safety connector that cannot be connected to an AC power outlet. The EMG Electrodes are provided sterile and for single patient use.

Dear Mr. Syring:
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 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). You may, therefore, market the device, subject to the general controls Costions 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 ( remailed in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, 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 mopellish 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.
