Intended Use

MRI SYSTEMS, including ASM-030PIII (OPENMARK III), ASM-040P (OPENMARK 4000) and ASM-050P (OPENMARK 5000), are indicated for use as magnetic resonance diagnostic devices (MRDD) that produce transverse, sagittal, coronal and oblique cross sectional images, and that display the internal structure and/or function of the head, body, or extremities. These images when interpreted by a trained physician yield information that may assist in diagnosis.

Device Story

Open permanent magnet MRI system (0.3T, 0.4T, 0.5T field strengths); models ASM-030PIII, ASM-040P, ASM-050P. Components: magnet, magnet enclosure, patient table, gradient coil, RF transmission/receiver coils, client PC, imaging cabinet. Operates by generating magnetic resonance signals to produce cross-sectional images (transverse, sagittal, coronal, oblique). Used in clinical settings by trained medical professionals. System software (APEX) provides interactive interface for image acquisition and display. Interpreted images assist physicians in diagnosing internal structures and functions of head, body, or extremities.

Clinical Evidence

Bench testing only. Compliance verified against IEC 60601-1, IEC 60601-1-2, IEC 60601-2-33, and NEMA MS-1, MS-2, MS-3, and MS-5 standards for image quality and safety.

Technological Characteristics

Open permanent magnet MRI system; 0.3T, 0.4T, 0.5T field strengths. Components: magnet, patient table, gradient/RF coils. Connectivity: Client PC. Software: APEX. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-33, NEMA MS-1, MS-2, MS-3, MS-5.

Indications for Use

Indicated for patients requiring diagnostic imaging of head, body, or extremities via magnetic resonance. Used by trained physicians to assist in diagnosis.

Regulatory Classification

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).

Special Controls

*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.

Predicate Devices

• Pica Whole Body MRI System (K091580)

#### Dear Mr. Mouser:

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 class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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 Parts 801 and 809); medical device reporting (reporting of

{4}------------------------------------------------

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed nredicate 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 Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number [phone] or [phone] or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
