Intended Use

The Toshiba 3T Extra Large Knee Coil is intended for use with a Toshiba Vantage Titan 3T MRI system to produce diagnostic images of the knee that can be interpreted by a trained physician.

Device Story

The Toshiba 3T Extra Large Knee Coil is a specialty magnetic resonance imaging (MRI) coil designed for use with the Toshiba Vantage Titan 3T MRI system. It functions as a receiver coil to capture radiofrequency signals from the knee during MRI procedures. The device is used in clinical settings by trained medical professionals to produce diagnostic images of the knee. These images are interpreted by a physician to assist in clinical decision-making and diagnosis. The coil is designed to accommodate larger anatomy, providing diagnostic utility for patients requiring knee imaging.

Clinical Evidence

Bench testing only. Compliance with IEC 60601-1 (general safety) and IEC 60601-2-33 (MRI safety/SAR) was demonstrated. Signal-to-noise ratio (SNR) was verified using internal protocols.

Technological Characteristics

Specialty MRI receiver coil; compatible with Toshiba Vantage Titan 3T system. Complies with IEC 60601-1 and IEC 60601-2-33 standards for safety and SAR. Passive hardware device; no software or active electronic processing components described.

Indications for Use

Indicated for patients requiring diagnostic MRI imaging of the knee using the Toshiba Vantage Titan 3T MRI system. No specific age or gender contraindications stated.

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.

The Toshiba 3T Extra Large Knee Coil and the predicate device have the same intended use, are of the same design, and are constructed of the same materials.

## 11. Non-Clinical Tests

The Toshiba 3T Extra Large Knee Coil was tested to and found complaint with IEC 60601-1, Medical electrical equipment - Part 1: General requirements for basic safety and essential performance, 1988 plus Amendments 1 (1991) and 2 (1995). The coil SAR complies with the requirements of IEC 60601-2-33, Particular requirements for the basic safety and essential performance of magnetic resonance equipment for medical diagnosis, 2002 plus Amendment 1 (2005). The signal-to-noise ratio (SNR) was measured according to Toshiba Medical Systems Corporation's internal protocol.

# 12. Conclusion

It is the opinion of Quality Electrodynamics that the Toshiba 3T Extra Large Knee Coil is substantially equivalent to the above-listed legally marketed predicate device. Use of the Quality Electrodynamics coil does not result in any new potential hazards.

Dear Ms. Zydyk:

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.
