AI/ML Overview

The provided text is a 510(k) premarket notification letter from the FDA regarding a medical device, the "OTI Femoral Lock Total Hip System." This document establishes that the device is "substantially equivalent" to legally marketed predicate devices, allowing it to proceed to market.

However, the provided text does not contain any information about:

Acceptance criteria for device performance.
A study proving the device meets acceptance criteria.
Reported device performance.
Sample sizes for test or training sets.
Data provenance.
Number or qualifications of experts for ground truth.
Adjudication methods.
MRMC comparative effectiveness studies.
Standalone algorithm performance.
Type of ground truth used.
How ground truth for the training set was established.

This document is a regulatory approval letter based on "substantial equivalence" to a predicate device, meaning it's deemed as safe and effective as a similar device already on the market. It does not outline specific performance metrics or clinical study results in the way a newer, novel device approval or studies for AI/software devices might.

Therefore, the requested information cannot be extracted from the provided text.

Dear Mr. Son:

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. ਸ substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Druq Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation may result in requlatory 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.
