Equivalence #### Intended Use The intended use of the Flex and Loop Coil Set 1.5 T is, in conjunction with a Magnetic Resonance Scanner, the MR examination of the human body. Used in the MAGNETOM Avanto, Espree and Symphony a Tim System, the Flex and Loop Coils are intended to produce transversal, sagittal, coronal and oblique images of the internal structures of the body. #### Device Description The Flex and Loop Coil Set 1.5 T consists of five receive-only coils and one interface, which contains the preamplifiers, cable traps and a combiner network. The coils are two 4-channel flexible coils (Flex Coil Large and Flex Coil Small) and three linear polarized (LP) flexible coils (Loop Coil 4 cm, 7 cm and 11 cm). Image /page/1/Figure/8 description: The image shows two lines labeled (1) and (2). According to the text, (1) is the coil socket and (2) is the plug for the coil socket on the patient table. The lines point to the respective parts in the image. Figure 8.II.1: Flex loop interface {2}------------------------------------------------ Image /page/2/Figure/1 description: The image shows three diagrams of a coil loop and coil plug. Each diagram has two labeled parts: (1) Coil loop and (2) Coil plug. The diagrams are simple line drawings, and the labels are placed near the corresponding parts of the coil. Figure 8.II.2: Loop coils 4 cm, 7 cm, and 11 cm Image /page/2/Figure/3 description: The image shows two diagrams of an electronic component, possibly a circuit board or a similar device. Each diagram has labels indicating different parts: (1) Center markings, (2) Electronic boxes, and (3) Coil plug. The diagrams appear to be technical illustrations, providing a visual representation of the component's structure and key features.

The following parameters were considered for the new Flex and Loop Coil Set 1.5 T [Safety] - Biocompatibility [Performance] - Signal to Noise Ratio - Image Uniformity No new materials were used for the new Flex and Loop Coil Set 1.5 T compared to their predicate device. Therefore no biocompatibility tests were performed. Signal to Noise Ratio (SNR) and image uniformity tests acc. to NEMA MS-6 standard were performed for the new Flex and Loop Coil Set 1.5 T and the results presented in this submission show that they are equivalent with the predicate devices. #### Conclusion as to Substantial Equivalence Laboratory testing was performed to support this claim of substantial equivalence and to show that the technological differences do not raise any new questions pertaining to effectiveness. {5}------------------------------------------------ Image /page/5/Picture/1 description: The image shows a circular logo with the words "DEPARTMENT OF HEALTH & HUMAN SERVICES - USA" arranged around the perimeter. Inside the circle is a stylized emblem resembling an eagle or bird in flight, composed of three curved lines that suggest feathers or wings. The logo is presented in black and white, with the text and emblem appearing in black against a white background.

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 (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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Image /page/5/Picture/10 description: The image is a black and white circular logo. The logo contains the text "1886-1986" at the top, followed by the letters "PA" in a large, bold font. Below the letters, the word "Centennial" is written in a cursive font. There are four stars at the bottom of the logo. The logo appears to be a commemorative emblem for the centennial anniversary of an organization or event. Protesting and Promoting Public Health {6}------------------------------------------------ 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.
