The description focuses solely on the hardware components and function of an MRI coil, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No
The device is described as a phased array coil that receives NMR signals for imaging purposes, not for treating or rehabilitating a medical condition.
No
Explanation: This device is a phased array coil for Magnetic Resonance (MR) imaging, which is a tool for acquiring images. While these images are used for diagnosis, the coil itself is an imaging component, not a diagnostic device that interprets data or provides a diagnosis.
No
The device description explicitly states it consists of hardware components: "four coil elements and PC board."
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that this device is a "phased array coil that can receive NMR signal" for "Imaging of the extremities (Foot and Hand), joints (knee, shoulder, ankle, wrist and elbow), and body (chest, abdomen and pelvis)". This is a component used in Magnetic Resonance (MR) imaging, which is an in vivo (within the living body) imaging modality.
- No Sample Analysis: There is no mention of analyzing samples taken from the body. The device interacts directly with the patient's body to acquire imaging data.
Therefore, the 4ch Flex SPEEDER is a component of an MR imaging system, which is used for diagnostic imaging of the body, not for diagnostic testing on samples from the body.

Device Description
The 4ch Flex SPEEDER is a phased array coil that can receive NMR signal from the extremities, joints, and trunk of the body. The 4ch Flex SPEEDER is mechanically flexible, and can wrap around various regions as mentioned above.
The 4ch Flex SPEEDER consists of four coil elements and PC board. The coil elements shape single loop and the four single loop coil elements are arranged to the row. The coil is decoupled during transmission from QD whole body by means of activating the PIN diodes.

§ 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.

Dear Mr. Biggins:
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 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
3
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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.
You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 796-7100 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
