Not Found
I am sorry, but based on the provided document, there is no information available regarding the acceptance criteria, the study that proves the device meets the acceptance criteria, or any details about a clinical study.
The document is a 510(k) clearance letter from the FDA to Nanma Manufacturing Co., Ltd. for their "Nanma Adjustable Constriction Rings." This letter indicates that the device has been found substantially equivalent to legally marketed predicate devices, allowing it to be marketed.
The document does NOT contain:
- A table of acceptance criteria or reported device performance.
- Information on sample size, data provenance, number of experts, adjudication methods for a test set.
- Details about a multi-reader multi-case (MRMC) comparative effectiveness study or standalone algorithm performance.
- Information on the type of ground truth used or the sample size and establishment of ground truth for a training set.
The 510(k) process primarily focuses on demonstrating substantial equivalence to a predicate device, which often relies on comparative performance, materials, and intended use, rather than extensive new clinical studies with detailed acceptance criteria as one might find for a novel or higher-risk device PMA submission.

Dear Ms. Smith:
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 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.
{1}------------------------------------------------
This letter will allow you to begin marketing your device as described in your Section 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.
