Indications for Use
Indicated for obtaining diagnostic images of the carotid artery in patients undergoing MRI to assist physicians 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.

The enclosure of all the carotid coils above is the same. The enclosure, which may contact the patient, is made up of biocompatible material.
#### Intended Use
The carotid coil is a receive-only coil, used for high resolution imaging of the bifurcation of the carotid artery in 1.5T and 3T General Electric, Siemens and Philips Magnetic Resonance Imaging (MRI) systems. Nucleus Excited: Proton 1H
Anatomic regions: Carotid.
#### Indications for Use:
The Carotid Coil is used for obtaining diagnostic images of carotid in magnetic resonance imaging systems. These images, when interpreted by a trained physician, yield information that may assist in diagnosis.
### Comparison with Predicate Device:
Carotid Coil is similar to the Shanghai Chenguang Medical Technologies Co., Ltd. made predicate device in all aspects as follow:
Intended use- The carotid coil is a receive-only coil, used for high resolution imaging of the bifurcation of the carotid artery in 1.5T and 3T General Electric, Siemens and Philips Magnetic Resonance Imaging (MRI) systems. Anatomic regions: Carotid.
Indication for use- The Carotid Coil is used for obtaining diagnostic images of carotid in magnetic resonance imaging systems. These images, when interpreted by a trained physician, yield information that may assist in diagnosis.
Technical Characteristics-The MR system is an imaging device. The fundamental scientific technology of a radio frequency (RF) coil is that the coil receives radio frequency signals from the tissue of interest. It is intended to provide the physician with physiological and clinical information, obtained non-invasively and without the use of ionizing radiation.
The fundamental scientific technology of the subject device is the same as the predicate device.
Suitable standards - UL 60601-1, ISO 10993-5 and ISO 10993-10.
{2}------------------------------------------------
#### Conclusions
The submitted Carotid Coil has been proved to be safe and effective by performance tests, bio-compatibility tests and IEC60601-1 compliance tests.
As stated above, Carotid Coil complies with the appropriate medical device standards and is substantially equivalent to the predicate device in safety and effectiveness based on similarities in design features, overall indications for use, and technological characteristics.
It is the opinion of Shanghai Chenguang Medical Technologies Co. LTD. that the Carotid Coils are substantially equivalent to Shanghai Chenguang Medical Technologies Co. LTD. made Carotid Coil (K092962). Testing and usage of the Carotid Coils do not result in any new potential hazards.

Dear Mr. Chen:
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.
