No
The device description and intended use focus on a simple electrical stimulating instrument with no mention of AI or ML capabilities.
No
The device is used for locating and identifying nerves during surgery through stimulation, not for treating a condition or restoring function.
No.
The device is used to stimulate nerves for location and identification during surgery, rather than to diagnose a condition or disease. It is an instrument for surgical assistance, not diagnosis.
No
The device description explicitly states it consists of physical components like a stainless steel wire, insulation, and a connector, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "stimulation of cranial and peripheral motor nerves for location and identification during surgery." This is a direct interaction with the patient's body for a surgical procedure.
- Device Description: The device is a surgical instrument designed to deliver electrical stimulation to nerves.
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not process or analyze such specimens.
The device is clearly a surgical instrument used in vivo (within the living body) during a surgical procedure, not an in vitro diagnostic device.

Device Description
The design of the Rhythmlink International Monopolar Stimulating Instrument is similar to existing stainless steel stimulating instruments. The device consists of a stainless steel wire with biocompatible electrical insulation applied to selected portions, and proximal connector provided to attach the instruments to a monopolar stimulator. The distal surface of the instrument is non-insulated stainless steel to provide for tissue stimulation. The Rhythmlink International Monopolar Stimulating Instrument with cable assembly is a protected pin design and meets requirements of IEC 60601-1:1988 /A1:1991 /A2:1995 Clause 56.3(c) per 21 CFR 898.12.

Dear Mr. Mewborne:
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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
2
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometric's (OSB's) Division of Postmarket Surveillance at 240-276-3474. For questions regarding the reporting of device adverse events (Medical Device Reporting (MDR)), please contact the Division of Surveillance Systems at 240-276-3464.
