No
The description focuses on the hardware (coil) and its performance in generating images, with no mention of AI/ML for image processing, analysis, or interpretation.
No
The device is used to produce diagnostic images, not to treat a medical condition.
No
Explanation: The device is an MR coil, which is a component of an MR system used to produce images. It is not a diagnostic device itself, but rather an accessory that enables the MR system to create images that a trained physician can then interpret for diagnosis. The PREDICATE DEVICE section also suggests that it's a coil.
No
The device is a physical MR coil with a rigid plastic housing and electrical components, not solely software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The TxRx Knee 15 Flare MR Coil 1.5T is an accessory for an MRI system. Its function is to acquire images of the knee within the body using magnetic resonance technology. It does not analyze samples taken from the body.
- Intended Use: The intended use is to "produce diagnostic images of the knee that can be interpreted by a trained physician." This is a function of an imaging device, not an IVD.
The device is a component of an imaging system used for in vivo (within the living body) diagnosis, not in vitro (in glass, or outside the body) diagnosis.
N/A
Intended Use / Indications for Use
The TxRx Knee 15 Flare MR Coil 1.5T is intended for use with Siemens 1.5T MR systems to produce diagnostic images of the knee that can be interpreted by a trained physician.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Biocompatibility Testing: All surface materials on the TxRx Knee 15 Flare MR Coil 1.5T that are intended to come into direct or indirect contact with patient biological tissues, cells or body fluids have a history of safe use in previously cleared devices.
Electrical Safety and Electromagnetic Compatibility: The TxRx Knee 15 Flare MR Coil 1.5T was tested to and found to be compliant with AAMI/ANSI ES60601-1 and IEC 60601-2-33.
Surface heating was tested in accordance with AAMI/ANSI ES60601-1. The measured temperature of the surface of the coil never exceeded the maximum limit of 41°C.
SAR measurement testing was performed per NEMA MS-8 to provide data supporting that the partial body limits for SAR are controlled within the limits described in IEC 60601-2-33. The testing showed that the system controls the SAR limits for the TxRx Knee 15 Flare MR Coil 1.5T such that they remain below the IEC 60601-2-33 partial body limits.
Performance Testing - Bench: The SNR and uniformity of the TxRx Knee 15 Flare MR Coil 1.5T was analyzed per IEC 62464 and was found to conform to predetermined acceptance criteria.
Performance Testing - Clinical: In accordance with the FDA Guidance for Industry: Guidance for the Submission of Premarket Notifications for Magnetic Resonance Diagnostic Devices, clinical images from volunteer scanning of the knee were obtained from the TxRx Knee 15 Flare MR Coil 1.5T. These images were used to demonstrate that the TxRx Knee 15 Flare MR Coil 1.5T produces diagnostic quality images of the intended anatomy.
Key results: The electrical safety and electromagnetic compatibility and biocompatibility data support the safety of the TxRx Knee 15 Flare MR Coil 1.5T and the bench testing per the IEC standards and diagnostic quality sample clinical images demonstrates the performance and effectiveness of the device under the specified use conditions. This testing demonstrates that the TxRx Knee 15 Flare MR Coil 1.5T performs as well as or better than the unmodified device.

§ 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.
