More Information

Not Found

No
The summary describes a device that delivers electrical stimulation and allows for current adjustment, with no mention of AI or ML technologies.

No.
The device is indicated to stimulate nerves for location and identification during surgery, not for therapeutic treatment.

No

The device is used for stimulating and locating nerves during surgery, which is an intraoperative procedure and not a diagnostic process performed externally or prior to treatment for diagnosis.

No

The device description explicitly states that the device "carry stimulation current from the patient interface to the patient" and mentions "Electromechanical, dimensional, and visual design performance" and "Electrical safety & EMC testing to IEC 60601" in the performance studies, indicating it is a hardware 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 "stimulate cranial and peripheral motor nerves for location and identification during surgery." This is a direct interaction with the patient's body during a surgical procedure.
  • Device Description: The device "carry stimulation current from the patient interface to the patient." This confirms it's applying a stimulus to the patient.
  • Lack of In Vitro Activity: There is no mention of the device being used to examine specimens (like blood, tissue, or urine) outside of the body to provide information about a physiological state, health, or disease.

IVD devices are specifically designed to perform tests on samples taken from the body to diagnose or monitor conditions. This device is used in vivo (within the living body) for nerve stimulation and identification during surgery.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Design performance testing was completed to ensure the functionality and intended use of the NIM™ 35cm long surgeon control probe was met in accordance with external standards, and device specifications via pre-defined acceptance criteria. Bench engineering test samples were subjected to simulated real-life conditions during functional testing to establish baseline data and accelerated aging data. The testing included in this submission provides objective evidence through passing results that key technological characteristics such as the ones listed below are proven to be safe and effective. This performance testing was used to support substantial equivalence, proving the subject device is as safe and effective as its predicate device.

  • Electromechanical, dimensional, and visual design performance
  • Sterilization validation to ISO 11135:2014
  • Electrical safety & EMC testing to IEC 60601
  • Biocompatibility testing and risk analysis to ISO 10993-1:2018
  • Stability testing of proposed shelf life
  • Packaging performance of environmental conditioning to ISTA 3A and distribution simulation to ASTM D4169
  • Usability testing to IEC 62366-1:2015

Dear Alexandra Oliver:

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 app roval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies.combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
