Intended Use

To be used in conjunction with 3.0T GE HD series Magnetic Resonance scanners to produce diagnostic images of the shoulder that can be interpreted by a trained physician.

Device Story

Multi-element phased array receive-only MRI coil; used for shoulder imaging. Device consists of eight antennas in semi-flexible foam housing; antennas positioned with overlap or transformer decoupling to cancel mutual coupling; pre-amplifier decoupling reduces remaining interference. Secured to patient via cross-body strap. Includes active and passive transmit decoupling circuits (diodes) to ensure safety during RF transmit by switching to high impedance state. Used in clinical MRI settings; operated by trained radiology staff. Output is raw signal data processed by GE 3.0T MRI scanner into diagnostic images for physician interpretation. Benefits include improved SNR and easier patient setup compared to previous models.

Clinical Evidence

Bench testing only. Performance evaluated via SNR and image uniformity testing to demonstrate substantial equivalence to predicate devices.

Technological Characteristics

8-channel phased array receive-only coil; semi-flexible foam housing; active/passive transmit decoupling circuits (diodes); NEMA MS-6, IEC 60601-1, and IEC 60601-2-33 compliant. Standalone hardware component for MRI systems.

Indications for Use

Indicated for use with 3.0T GE HD series MRI scanners to produce diagnostic shoulder images for interpretation by trained physicians.

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.

Predicate Devices

• USA Instruments Inc. Mark III Phased Array Shoulder Coil (K042009)
• NeoCoil 1.5T Shoulder Array Coil Model NC008 (K071311)

Device Description:

The NeoCoil 3.0T 8-Channel Shoulder Array Coil is a multi-element phased array receive only coil used for obtaining diagnostic images of the shoulder in Magnetic Resonance Imaging Systems. Compared to predicate devices, the submitted device offers easier patient setup and greater SNR due to its compatibility with 3.0T MRI scanners.

The submitted device consists of semi-flexible foam covered housing, consisting of eight antennas. The antennas are uniquely positioned with the appropriate overlap to cancel out mutual coupling effects from adjacent antennas or decoupled from an adjacent antenna using a transformer. Pre-amplifier decoupling reduces any remaining decoupling between the antennas.

{1}------------------------------------------------

The coil is held in place over the imaging area via a cross body strap. A system interface cable connects to the coil at the top of the housing. The flexible foam covered housing along with the body strap enable the proper positioning on the patient before laying down and holds the coil in place while scanning is being performed.

To ensure safety, each antenna is equipped with active and passive transmit decoupling circuits. Active decoupling is achieved via diodes that receive signals from the scanner to turn the coil to a high impedance state during system RF transmit. Crossed diodes are installed on each antenna acting as passive switches. These passive switches provide additional safety in case the active circuitry does not receive signal from the scanner.

Predicate Devices: USA Instruments Inc. Mark III Phased Array Shoulder Coil (K042009). NeoCoil 1.5T Shoulder Array Coil Model NC008 (K071311)

Comparison to Predicate:

It is our opinion that the NeoCoil 3.0T 8-Channel Shoulder Array Coil in this submission is substantially equivalent to the previously cleared USA Instruments Inc. Mark III Phased Array Shoulder Coil (K042009), and the NeoCoil 1.5T Shoulder Array Coil Model NC008 (K071311).

In all material respects, the NeoCoil 3.0T 8-Channel Shoulder Array is substantially equivalent to the referenced predicate devices. SNR and image

Summary of Studies:

Conclusion:

uniformity testing was performed which support the conclusion that the submitted device satisfies design objectives. The NeoCoil 3.0T 8-Channel Shoulder Array is substantially equivalent to the

predicate device. Use of the NeoCoil 3.0T 8-Channel Shoulder Array does not result in any new potential hazards and does not alter the safety of the MRI scanner.

#### Dear Mr. Lehtonen:

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.
