It functions as a radiofrequency receiver coil to detect MR signals from peripheral anatomical regions, specifically the TMJ and wrist. The device is intended for use in clinical MRI environments by trained radiology personnel. By utilizing superconducting materials, the coil aims to improve signal-to-noise ratio (SNR) compared to conventional copper coils, potentially enhancing image quality for superficial structures. The output is processed by the host MRI system to generate diagnostic images, which clinicians use to evaluate anatomical structures and pathology. The device is limited to anatomies no deeper than 1.5 inches from the skin. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics High-temperature superconducting (HTS) material; surface coil form factor; radiofrequency receiver coil for MRI; intended for superficial imaging (depth ≤ 1.5 inches). ## Regulatory 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). ## Special Controls *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. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

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 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 the letter: | 8xx. 1xxx | (301) 594-4591 | |----------------------------------|----------------| | 876.2xxx, 3xxx, 4xxx, 5xxx | (301) 594-4616 | | 884.2xxx, 3xxx, 4xxx, 5xxx, 6xxx | (301) 594-4616 | | 892.2xxx, 3xxx, 4xxx, 5xxx | (301) 594-4654 | | Other | (301) 594-4692 | Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
