## Summary of Technological Characteristics of the Principal Device as 7. Compared with the predicate Device

In comparison to the existing OR head holders, the OR Head Holder Flexibility PN: 114464 includes only some minor mechanical changes which contribute to more flexibility in patient positioning. According to our internal evaluations as well the external tests done by VDE the new components such as Z-joint meet the requirements of IEC 60601-1 3.ed (clause 9.8) and do not adversely affect the safety of the design.

#### 8. General Safety and Effectiveness Concerns

The NORAS OR Head Holder Flexibility combined with the NORAS OR Head Coil 1.5T / 3T will conform to the FDA recognized NEMA Standards for the measurement of performance and safety parameters and the IEC standards for safety issues with the Magnetic Resonance Imaging Devices, IEC 60601-2-33:2002. This will assure that the performance of this device can be considered safe and effective when used with the currently available Siemens MAGNETOM Aera/Skyra 1.5T/3T as well as Philips Ingenia 1.5T/3T systems.

#### Conclusion as to Substantial Equivalence 9.

NORAS MRI products GmbH believes that, within the definition of the Safe Medical Devices Act of 1990, the NORAS OR Head Holder Flexibility is substantially equivalent to the predicate device listed above.
