Intended Use
The Lesion Probe and Generator system is intended to create radiofrequency (RF) heat lesions in nerve tissue. It is intended for use only by trained clinicians in a hospital or clinical setting.
Device Description
The GFX Nerve Ablation System provides a minimally invasive technique for creating a neural lesion inhibiting the function of the target nerve. The Generator and probe are used as a system to both stimulate the nerve for the purpose of locating the probe correctly and to create a neural lesion to inhibit nerve function through the application of RF energy. The GFX Nerve Ablation probes are single use devices supplied sterile to the customer.
More Information

Not Found

No
The summary describes a standard RF ablation system for nerve tissue, with no mention of AI or ML in the intended use, device description, or specific sections for AI/ML details.

Yes
The system creates lesions in nerve tissue to inhibit nerve function, which is a therapeutic intervention.

No
Explanation: The device creates lesions in nerve tissue and stimulates nerves for proper probe placement, indicating a therapeutic or interventional function rather than a diagnostic one.

No

The device description explicitly mentions a "Generator and probe" which are hardware components used to deliver RF energy and create lesions. This is not a software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to "create radiofrequency (RF) heat lesions in nerve tissue." This is a therapeutic procedure performed directly on the patient's body, not a test performed on a sample taken from the body.
  • Device Description: The description confirms it's a "minimally invasive technique for creating a neural lesion inhibiting the function of the target nerve" through the application of RF energy. This is a treatment, not a diagnostic test.
  • Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.), detecting substances, or providing diagnostic information based on in vitro analysis.

IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device performs a therapeutic action directly on the patient.

Dear Mr. Anselmo:

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.
