No
The device description focuses on manual surgical instruments with electrical stimulation capabilities, and there is no mention of AI, ML, or related concepts in the provided text.
No
The device is described as a surgical instrument for tissue dissection and nerve stimulation, which are diagnostic and procedural functions performed during surgery, not therapeutic interventions.
No
The device is indicated for "tissue dissection and stimulation of cranial and peripheral motor nerves for location and identification during surgery." While "identification" might seem diagnostic, the primary function of "location and identification" within the context of "stimulation" of nerves during surgery is to guide the surgeon's actions and prevent damage, rather than to provide a diagnosis of a disease or condition. It's an intraoperative tool for guidance, not for diagnosing a patient's medical state.
No
The device description clearly outlines physical instruments made of stainless steel with electrical insulation and connectors, 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 "tissue dissection and stimulation of cranial and peripheral motor nerves for location and identification during surgery." This describes a surgical tool used directly on the patient's body during a procedure.
- Device Description: The description details surgical instruments (scissors, retractors, etc.) with electrical insulation and connectors for a stimulator. This aligns with surgical tools, not devices used to test samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.) or providing diagnostic information based on such analysis. IVDs are designed to perform tests in vitro (in glass, or outside the living organism).
The device is clearly intended for use in vivo (within the living organism) during surgery.

Device Description
The designs of the Stimulus - Dissection Instruments are similar to existing stainless steel manual surgical instruments. The instruments consist of scissors, retractors, awls, taps, needles, probes, and hooks with biocompatible electrical insulation applied to selected portions, and proximal connectors provided to attach the instruments to a monopolar stimulator. The distal surfaces of the instruments are non-insulated stainless steel to provide for mechanical, manual dissection / resection, and tissue stimulation. The Stimulus - Dissection Instruments are a protected pin design and meet the requirements of IEC 60601-1:1988 /A1:1991 /A2:1995 Clause 56.3(c) per 21 CFR 898.12. Accessories include monopolar cables available in lengths up to 3 M.

Dear Mr. Sargent:
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.
