The description focuses on the hardware components and physical design of an MRI coil, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No.
The device is an MRI receive-only coil used for imaging, not treatment.
Yes
Explanation: The device is a Magnetic Resonance Imaging (MRI) coil used for foot and ankle imaging. MRI is a diagnostic imaging technique used to visualize internal structures of the body to aid in diagnosis.
No
The device description clearly states it is a physical surface coil comprised of hardware components like coil elements, preamplifiers, and a base plate, and verification testing includes hardware-related standards (IEC 60601-1, IEC 60601-1-2).
No, 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 (like blood, urine, or tissue) to detect diseases, conditions, or infections.
- Device Function: The provided description clearly states that the 8ch Foot Ankle Coil is a receive-only RF surface coil designed for use with GE 1.5T MRI systems for foot and ankle imaging. It is a component of an MRI system used to acquire images of the body.
- No Sample Analysis: The device does not analyze any biological samples taken from the patient. It receives radiofrequency signals emitted by the patient's body during an MRI scan.
Therefore, based on the provided information, the 8ch Foot Ankle Coil is a medical device used for imaging, not an in vitro diagnostic device.

Device Description
The 8ch Foot Ankle Coil is a surface coil used for Magnetic Resonance Imaging. It's tuned to image Proton nuclei in a receive-only configuration. It is comprised of 8 individual Phased Array coil elements which receive the signal from patient's foot or ankle. Preamplifiers are integrated in the coil. The geometry is optimized for use with parallel imaging techniques.
The 8ch Foot Ankle Coil comprises the coil and the base plate. The coil conforms to patients' anatomy, accommodating various foot contours while minimizing patient discomfort. The base plated from the coil part is used to place the patients' anatomy on the table.

§ 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. Xi:
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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
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.
