Not Found
The provided document is a 510(k) clearance letter from the FDA for a medical device called "Sowell Cobalt-Chrome Metal Alloy." This type of letter generally does not include detailed study information, acceptance criteria, or performance data in the way a clinical study report or a premarket approval (PMA) application summary would.
The 510(k) process is primarily focused on demonstrating substantial equivalence to a predicate device, rather than proving safety and effectiveness de novo through extensive clinical trials. Therefore, the document does not contain the specific information requested in your prompt regarding acceptance criteria and a study proving device performance.
Here's why the prompt cannot be answered from the provided text:
- No Acceptance Criteria: The letter does not define any specific performance metrics or thresholds for the device.
- No Study Details: There is no mention of a study design, sample sizes, ground truth establishment, expert qualifications, or adjudication methods.
- No Reported Performance: The letter only grants clearance based on substantial equivalence; it does not report any performance statistics for the device itself.
- No AI Component: This device is a metal alloy, not an AI/ML-driven software device. Therefore, questions regarding MRMC studies, standalone algorithm performance, or human improvement with AI assistance are not applicable.
In summary, the provided document does not contain the information necessary to describe the acceptance criteria and the study that proves the device meets those criteria, as typically found for AI/ML medical devices or devices requiring extensive performance data.

Dear Ms. Chin:
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 Requlations, Title 21, Parts 800 to 895. ਸੇ substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation 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 regulations.
