Intended Use
The Alpha 7000 Quadrature Wrist Coil is a receive-only quadrature RF coil, used for obtaining diagnostic images of the wrist and hand anatomy in Magnetic Resonance Imaging systems. The indications for use are the same as for standard MR Imaging. The Quadrature Wrist Coil is designed for use with GE Signa (1.5 Tesla) MRI scanner manufactured by GE Medical Systems. The Alpha 7000 Quadrature Wrist Coil is designed to provide Magnetic Resonance Images of the wrist and hand anatomy. The Alpha 7000 Quadrature Wrist Coil is designed for use with the GE Signa (1.5 Tesla) MRI Scanner. The GE Signa system is indicated for use as an NMR device that produces images that: (1) correspond to the distribution of protons exhibiting NMR signal, (2) depend upon NMR parameters (proton density, spin lattice relaxation time T1, spin-spin relaxation time T2) and (3) display the soft tissue structure of the head and whole body. When interpreted by a trained physician, these images yield information that can be useful in the determination of a diagnosis.
Device Description
The Alpha 7000 Quadrature Wrist Coil consists of two volume RF coil elements in a quadrature design. The elements and the associated circuitry are enclosed in a durable housing made of polyurethane material, which is fire rated and has high impact and tensile strength.
More Information

Not Found

No
The document describes a passive RF coil for MRI, with no mention of software, algorithms, or any technology related to AI/ML.

No
The device is described as a receive-only RF coil used for obtaining diagnostic images, which yields information useful for diagnosis, not directly for therapy.

No

The Alpha 7000 Quadrature Wrist Coil is a receive-only RF coil used to obtain images for diagnosis, but it does not perform the diagnosis itself. The diagnostic interpretation is done by a trained physician.

No

The device description clearly states it consists of physical components (RF coil elements, circuitry, housing) and is a hardware device used in conjunction with an MRI system.

Based on the provided information, the Alpha 7000 Quadrature Wrist Coil is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Alpha 7000 Quadrature Wrist Coil is a component of an MRI system. Its function is to receive radiofrequency signals from the patient's body during an MRI scan to create images of the wrist and hand anatomy.
  • No Specimen Analysis: The device does not analyze any specimens taken from the body. It interacts directly with the patient's body to acquire imaging data.

Therefore, the Alpha 7000 Quadrature Wrist Coil falls under the category of a medical imaging device, not an In Vitro Diagnostic 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 Mr. Thomas:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 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 Part 801 and additionally 809.10 for in yitzo diagnostic devices), please contact the Office of Compliance at (301) 594-4613. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation of the regulation of "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsmamain.html".
