The summary describes a passive MRI coil and does not mention any AI/ML components or image processing capabilities beyond standard MRI acquisition.
No
The device is intended to produce diagnostic images, not to provide therapy.
No
Explanation: The device is an MRI coil used to produce diagnostic images, but it does not perform the diagnosis itself. The images are interpreted by a trained physician for diagnosis.
No
The device description explicitly states it is a "receive-only, 12-channel phased array coil," which is a hardware component used in MRI.
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 about a person's health. This testing is done outside of the body (in vitro).
- Device Function: The Contour Hand/Wrist is an MRI coil. It is a component used with an MRI system to acquire images of the hand and wrist within the body (in vivo). It does not analyze biological specimens.
- Intended Use: The intended use is to "produce diagnostic images of hand and wrist anatomy." This is a function of an imaging device, not an IVD.
The information provided clearly describes a medical imaging accessory used for in vivo diagnostic imaging, not an in vitro diagnostic test.

Summary of Performance Studies
The signal-to-noise ratio (SNR) and image uniformity of the Contour Hand/Wrist were measured on a 0.55T Siemens MR System, manufactured by Siemens Healthineers. The SNR and uniformity of the Contour Hand/Wrist were analyzed per NEMA MS-9 (using alternate method 2,5 from MS-6) and uniformity was analyzed using NEMA MS-9 (primary method from MS-6) using pre-determined acceptance criteria.
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 hand/wrist anatomy were obtained from a Siemens 0.55T MR system. These images were used to demonstrate that the Contour Hand/Wrist produces diagnostic quality images of the intended anatomy. No adverse events were reported or recorded.
The electrical safety and electromagnetic compatibility and biocompatibility data support the safety of the Contour Hand/Wrist 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 Contour Hand/Wrist performs as well as or better than the predicate 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.

Dear JoVanna Boudreaux:
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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Device Description Summary
The Contour Hand/Wrist is a receive-only, 12-channel phased array coil designed for magnetic resonance imaging (MRI) using the Siemens 0.55T MR systems. The Contour Hand/Wrist is intended to be used for imaging hand and wrist anatomy.
Intended Use/Indications for Use
The Contour Hand/Wrist is intended for use with Siemens 0.55T MR systems to produce diagnostic images of hand and wrist anatomy that can be interpreted by a trained physician.
Indications for Use Comparison
The Indications for Use statement for the Contour Hand/Wrist is not identical to that of the predicate device (Contour Knee); however, the differences do not affect the safety or effectiveness of the device relative to the predicate device. Both Indications for the proposed Contour Hand/Wrist and predicate Contour Knee indicate that the device is intended to be used in conjunction with a MR system to produce images of human anatomy and that the images can be interpreted by a trained physician. The indications for use statements differ only in that the proposed Contour Hand/Wrist is intended for use to image hand and wrist anatomy instead of knee anatomy.
Technological Comparison
At a high level, the proposed and predicate device are based on the following same technological elements:
- Receive-only phased array RF coil
- · Active PIN diode switching blocking circuitry. Passive blocking circuitry.
- Materials used for flame retardancy and biocompatibility: Polycarbonate and aramid felt with a polyurethane coated nylon fabric cover
The following technological differences exist between the proposed and predicate device:
- Intended for use (hand and wrist anatomy (proposed device) versus knee anatomy (predicate device))

The signal-to-noise ratio (SNR) and image uniformity of the Contour Hand/Wrist were measured on a 0.55T Siemens MR System, manufactured by Siemens Healthineers. The SNR and uniformity of the Contour Hand/Wrist were analyzed per NEMA MS-9 (using alternate method 2,5 from MS-6) and uniformity was analyzed using NEMA MS-9 (primary method from MS-6) using pre-determined acceptance criteria.
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 hand/wrist anatomy were obtained from a Siemens 0.55T MR system. These images were used to demonstrate that the Contour Hand/Wrist produces diagnostic quality images of the intended anatomy. No adverse events were reported or recorded.
The electrical safety and electromagnetic compatibility and biocompatibility data support the safety of the Contour Hand/Wrist 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 Contour Hand/Wrist performs as well as or better than the predicate device.
