The Ad-Tech Spinal Electrode addressed in this premarket notification has identical materials, technological characteristics, sterilization procedures and packaging as the commercially available Ad-Tech Depth Electrode (K891920B). The device has similar intended use, materials and technological characteristics to the commercially available Nicolet Epidural Spinal Electrode (K882053). Like this device, the Ad-Tech Spinal Electrode is to be placed epidurally for monitoring evoked potentials.

AI/ML Overview

The provided 510(k) summary for the Ad-Tech's Spinal Electrode does not contain the information requested regarding acceptance criteria or a study proving the device meets said criteria.

Instead, the submission focuses on demonstrating substantial equivalence to a predicate device (Nicolet Epidural Spinal Electrode K882053) based on:

Identical materials, technological characteristics, sterilization procedures, and packaging to a commercially available Ad-Tech Depth Electrode (K891920B).
Similar intended use, materials, and technological characteristics to the Nicolet Epidural Spinal Electrode.

The document states: "Ad-Tech believes that the information provided in this premarket notification clearly demonstrate that it is safe and equivalent to the mentioned commercially marketed predicate device." This implies that the 'acceptance criteria' for this 510(k) submission was substantial equivalence, not specific performance metrics demonstrated through a detailed study on the new device.

Therefore, the following information cannot be extracted from the given text:

A table of acceptance criteria and the reported device performance: Not present. The submission relies on equivalence.
Sample size used for the test set and the data provenance: Not applicable, no specific test set or study is described for the new device's performance.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
Adjudication method for the test set: Not applicable.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and its effect size: Not applicable.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable, as this is a physical medical device, not an algorithm.
The type of ground truth used: Not applicable.
The sample size for the training set: Not applicable.
How the ground truth for the training set was established: Not applicable.

In summary, this 510(k) submission is for a medical device that established substantial equivalence to a predicate device, rather than providing performance data against specific acceptance criteria for a new, innovative technology.

Dear Mr. Allen:

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 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 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 (Premarket Approval), 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 895. ਕੇ substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, 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 comply with 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 requlations.

{3}------------------------------------------------

This letter will allow you to begin marketing your device as described in your 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 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4659.
