The coil is indicated for use, on the order of a physician, in conjunction with an MR scanner as an accessory to produce images of the anatomy of interest, as an aid to diagnosis / treatment.
Not Found
The provided text outlines the FDA's clearance of the Invivo Corporation's Model HRK-63-16 and HRK-127-16 Knee Array Coils but does not contain information regarding objective performance criteria, a study proving the device meets these criteria, or details of algorithm performance.
The document is a 510(k) clearance letter, which means the device was found substantially equivalent to a predicate device. This process primarily focuses on demonstrating that the new device is as safe and effective as a legally marketed predicate, rather than establishing efficacy against predefined objective performance criteria through a specific clinical study for the new device.
Therefore, the requested information elements cannot be extracted from this document:
- A table of acceptance criteria and the reported device performance: Not provided.
- Sample size used for the test set and the data provenance: Not provided.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience): Not provided.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not provided.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable, as this is a coil device, not an AI algorithm, and no such study is mentioned.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not provided.
- The sample size for the training set: Not applicable.
- How the ground truth for the training set was established: Not applicable.
The document indicates that the device is an "accessory to produce images of the anatomy of interest, as an aid to diagnosis/treatment" in conjunction with an MR scanner. The clearance is based on the device being "substantially equivalent" to predicate devices, meaning it likely underwent testing to ensure specifications (e.g., signal-to-noise ratio, image uniformity, mechanical integrity) were comparable or better than existing coils, but these specific test results and acceptance criteria are not detailed in this regulatory letter.

Trade/Device Name: Model HRK-63-16 and HRK-127-16 Knee Array Coils Regulation Number: 21 CFR 892.1000 Regulation Name: Magnetic resonance diagnostic device Regulatory Class: II Product Code: MOS Dated: June 16, 2008 Received: October 7, 2008
Dear Mr. Adams:
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 such 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.
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.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter:
| 21 CFR 876.xxx | (Gastroenterology/Renal/Urology) | 240-276-0115 |
|---|---|---|
| 21 CFR 884.xxx | (Obstetrics/Gynecology) | 240-276-0115 |
| 21 CFR 894.xxx | (Radiology) | 240-276-0120 |
| Other | 240-276-0100 |
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometrics' (OSB's) Division of Postmarket Surveillance at 240-276-3474.

§ 892.1000 Magnetic resonance diagnostic device.
(a)
Identification. A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).(b)
Classification. Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
