USA - **Product Code:** [MOS](/submissions/RA/subpart-b%E2%80%94diagnostic-devices/MOS.md) - **Decision Date:** Mar 25, 2005 - **Decision:** SESE - **Submission Type:** Traditional - **Regulation:** 21 CFR 892.1000 - **Device Class:** Class 2 - **Review Panel:** Radiology ## Indications for Use The Cordless coil is a receive type surface coil. When used in the MAGNETOM Concerto and C! MR systems, it is indicated for use as a when about in alle interese to produce transverse, sagittal, coronal and oblique images of internal structures of the brain and body surface. The images produced reflect the spatial distribution of protons exhibiting magnetic resonance. Spectra allow the molecules containing the nucleus under investigation to be distinguished. The NMR properties that determine the image and spectra appearance are spin density, spin-lattice relaxation time (T1), and spin-spin echo time (T2) of the corresponding nucleus. When interpreted by a trained physician, these images and spectra provide information that can be useful in making diagnoses. ## Device Story Cordless coil is a receive-type surface coil set consisting of two coils; one coupling loop connected via cable and one receive coil inductively coupled to the other. Used within MAGNETOM Concerto and C! MR systems to acquire magnetic resonance signals from internal brain and body surface structures. Device transforms proton spin density, T1, and T2 relaxation data into transverse, sagittal, coronal, and oblique images and spectra. Operated by trained clinical staff in a radiology environment. Output is interpreted by a physician to assist in clinical diagnosis. Benefits include non-invasive visualization of internal anatomy. ## Clinical Evidence No clinical data. Bench testing only. Performance and safety parameters verified against FDA-recognized NEMA standards and IEC 60601-2-33:2002. ## Technological Characteristics Receive-type surface coil set; inductive coupling mechanism; dimensions/form factor specific to MAGNETOM Concerto and C! systems; conforms to IEC 60601-2-33:2002 for MR safety; no active software algorithm; passive hardware component. ## Regulatory 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 - Coils used with Siemens Medical Solutions MAGNETOM Concerto ([K003192](/device/K003192.md)) - Coils used with Siemens Medical Solutions MAGNETOM C!

Safety and Effectiveness Supporting Substantial Equivalence #### Intended Use The Cordless coil is a receive type surface coil. When used in the MAGNETOM Concerto and C! MR systems, it is indicated for use as a when about in alle interese to produce transverse, sagittal, coronal and oblique images of internal structures of the brain and body surface. The images produced reflect the spatial distribution of protons exhibiting magnetic resonance. Spectra allow the molecules containing the nucleus under investigation to be distinguished.

It is a set consisting of two coils. The coupling loop is connected with a cable and one receive coil is inductively coupled to the other. ### Substantial Equivalence Rabid and Siemens believe that, within the meaning of the Safe Medical Devices Act of 1990, the cordless coil for MAGNETOM Concerto and MAGNETOM C! is substantially equivalent to : | Coil Name | Premarket Notification | Clearance Date | |----------------------------------------------------------------|------------------------|----------------| | Coils used with Siemens Medical Solutions
MAGNETOM Concerto | K003192 | 12/21/2000 | | Coils used with Siemens Medical Solutions
MAGNETOM C! | K043030 | 12/09/2004 | The Cordless Coil for MAGNETOM Concerto and C! described in this Premarket Notification has the same intended use and similar technical characteristics as the devices listed above. In summary, Rapid Biomedical and Siemens are of the opinion that the Cordless coil does not introduce any new safety risks and is substantially equivalent to, and performs as well as, the predicate devices. ## General Safety and Effectiveness Concerns The cordless coil for MAGNETOM Concerto and MAGNETOM C! will conform to the FDA recognized NEMA Standards for the measurement of performance and safety parameters and the IEC standard for safety issues with Magnetic Resonance Imaging Devices, IEC 60601-2-33: 2002. This will assure that the performance of this device can be considered safe and effective with respect to the currently available MAGNETOM Concerto and C! systems. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
