More Information

Not Found

No
The summary describes a receive-only MRI coil and does not mention any software or algorithms that would incorporate AI or ML.

No
The device is described as a receive-only coil for MR imaging, which is a diagnostic tool, not one that provides therapy or treatment.

Yes

This device is a receive-only coil used with MRI scanners for imaging specific anatomical sites (intracranial/extracranial Neurovascular, skull base, and C-Spine). Imaging is a core component of diagnostic processes when a physician interprets those images to make a diagnosis. The device's function is to facilitate the acquisition of these images, making it a component of a diagnostic system.

No

The device description explicitly states it is a "receive-only coil," which is a hardware component used in MRI systems.

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.
  • Device Function: The description clearly states that this device is a "receive-only coil" used with MRI scanners for "MR imaging of the intracranial/extracranial Neurovascular, skull base and C-Spine." This is an imaging device that interacts directly with the patient's body to capture images, not a device that analyzes samples taken from the body.

Therefore, based on the provided information, the Medrad Phased Array Neurovascular coil is an in vivo imaging device, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Test results demonstrate that the design specifications for the Medrad 8-Receiver Phased Array Neurovascular Coil were met and that the Medrad 8-Receiver Phased Array Neurovascular Coil meets the applicable requirements of the international standards cited. Therefore, it has been determined that the Medrad 8-Receiver Phased Array Neurovascular Coil is substantially equivalent to the predicate device, its predecessor, for its intended use when used as prescribed in the User Operation Manual.

§ 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.

Substantial Equivalence: The information provided in this premarket notification demonstrates that the proposed device is substantially equivalent to a legally marketed device. The proposed 8-Receiver Phased Array Neurovascular Coil is substantially equivalent to the 1.5T Phased Array Neurovascular Coil (K984257)

The Medrad 8-Receiver Phased Array Neurovascular Coil maintains the same intended use, similar operational parameters, similar labeling and is used in a manner similar to the predicate device.

Like the Medrad 4-Receiver Neurovascular Coil, the Medrad 8-Receiver Neurovascular Coil is a receive-only coil intended to be used with the General Electric Superconducting MRI scanners for MR imaging of the intracranial Neurovascular, skull base and C-Spine without moving the patient or the coil, i.e., no scan room intervention

Medrad has established, as part of its Quality System, design controls in compliance with FDA's Quality System Regulations (QSRs). These design controls are applied to all Medrad product development processes and product design changes. These design controls were applied to the development of the Stellant CT Injector and meet the requirements of the FDA's QSRs.

As part of the design control a risk analysis was performed, and design verification and validation testing was conducted to support the conclusion drawn by the risk analysis.

Test results demonstrate that the design specifications for the Medrad 8-Receiver Phased Array Neurovascular Coil were met and that the Medrad 8-Receiver Phased Array Neurovascular Coil meets the applicable requirements of the international standards cited. Therefore, it has been determined that the Medrad 8-Receiver Phased Array Neurovascular Coil is substantially equivalent to the predicate device, its predecessor, for its intended use when used as prescribed in the User Operation Manual.

A comparison of features and principles of operation between the proposed device and predicate device is provided in the table below.

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 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.

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 Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.
