Used in the MAGNETOM ESSENZA, the 14-Channel Extremity Coil is indicated for use as a magnetic resonance diagnostic device (MRDD) to produce transverse, sagittal, coronal and oblique cross sectional images that display the internal structure and/or function of the knee, foot, ankle, hand and wrist. The images produced by the MAGNETOM ESSENZA with the, 14-Channel Extremity Coil reflects the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis. The intended use of the MAGNETOM ESSENZA is not affected in any way by the use of the new 14-Channel Extremity Coil. ## Device Story 14-Channel Extremity Coil accessory for 1.5T MAGNETOM ESSENZA MRI scanner; receives radiofrequency signals from human knee, foot, ankle, hand, or wrist; transforms signals into transverse, sagittal, coronal, and oblique cross-sectional images; used in clinical radiology settings by trained physicians; output images display internal structure/function based on proton spatial distribution; aids physician diagnosis; provides high-resolution diagnostic imaging of extremities. ## Clinical Evidence Bench testing only. Performance parameters including Signal to Noise Ratio (SNR), image uniformity, and Specific Absorption Rate (SAR) were tested and compared to the predicate device, demonstrating equivalence. ## Technological Characteristics 14-channel phased-array extremity coil; designed for 1.5T MAGNETOM ESSENZA MRI; RF sensing principle; materials identical to predicate; no new biocompatibility concerns; performance metrics include SNR, image uniformity, and SAR. ## 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. ## Predicate Devices - TxRx 15Ch Knee Coil 1.5T (QED) ([K082636](/device/K082636.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The following parameters were considered for the new 14-Channel Extremity Coil: Safety -RF Power Deposition -Biocompatibility ### Performance -Signal to Noise Ratio -Image Uniformity No new materials were used for the new 14-Channel Extremity Coil compared to the predicate device. Therefore no new biocompatibility tests were performed. Signal to Noise Ratio (SNR), image uniformity and SAR tests were performed for the new 14-Channel Extremity Coil and the results presented in this submission show that they are equivalent with the predicate devices. Conclusion as to Substantial Equivalence Laboratory testing was performed to support this claim of substantial equivalence and to show that the technological differences do not raise any new questions pertaining to effectiveness. {3}------------------------------------------------ Image /page/3/Picture/0 description: The image shows the logo for the Department of Health & Human Services - USA.

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 class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, ' Code of Federal Regulations (CFR), Parts 800 to 895. 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 Parts 801 and 809); medical device reporting (reporting of {4}------------------------------------------------ medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). 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 Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
