Intended Use

The Machnet Bilateral Open Breast Coil, Catalog Number MICS-GSXX, is for use in conjunction with a Magnetic Resonance Scanner to produce diagnostic images of the breast and axillary tissues that can be interpreted by a trained physician.

Device Story

The Machnet Bilateral Open Breast Coil is a dual-channel phased array coil assembly designed for use with GE Signa 1.5T, 1.0T, and 0.5T MRI scanners. It functions as a receive-only device to capture MR signals from breast and axillary tissues. The open-coil design accommodates various breast sizes and includes support/positioning features to minimize motion artifacts. It enables bilateral or unilateral imaging and supports high-sensitivity, thin-slice acquisition. Optional accessories (MICS-MIA/S) allow for interventional MRI and computer-assisted lesion localization (2-3 mm accuracy). The device is operated by trained clinicians in a clinical imaging environment. Output consists of raw MR signal data processed by the scanner into diagnostic images, which are interpreted by physicians to identify lesions and guide interventional procedures.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Dual-channel phased array coil assembly; receive-only; compatible with GE Signa 1.5T, 1.0T, and 0.5T MR scanners; open-coil architecture with integrated breast support/positioning; supports optional interventional localization accessories.

Indications for Use

Indicated for use with Magnetic Resonance Scanners to produce diagnostic images of breast and axillary tissues in patients requiring breast imaging.

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.

# 510(k) Summary of Safety and Effectiveness

- 1. Identification of the Device: Proprietary-Trade Name: "Machnet Bilateral Open Breast Coil" (Catalog # MICS-GSXX) (Classification Name: 90 MOS, COIL, MAGNETIC RESONANCE, SPECIALTY Common/Usual Name: Breast Coil Array Assembly
- 2. Equivalent legally marketed device: This device is similar in design and identical in function to the MRI Devices Corp. Model OBC-149 Breast Array Coil K003340
- 3. Indications for Use (intended use):. The Machnet Bilateral Open Breast Coil, Catalog Number MICS-GSXX, is for use in conjunction with a Magnetic Resonance Scanner to produce diagnostic images of the breast and axillary tissues that can be interpreted by a trained physician
- 4. Description of the device: The Machnet Bilateral Open Breast Coil is designed as a bilateral open breast coil which allows clinical imaging combined with very precise multiple localizations of breast lesions and subsequently small interventional breast procedures. Features: Dual channel phased array configuration. Allows bilateral and unilateral imaging of the breast and surrounding tissues. Minimal variation of contrast across images. The design allows adequate reception of signals from chest wall and axilla Ergonomic design minimizes motion artifacts. Open coil design allows virtually all sizes of breasts to be imaged. Breast support and positioning devices allow controlled positioning. High sensitivity allows thin slices. Interventional MRI possible with optional device (MICS-MIA). Accurate (2 to 3 mm) multiple computer-assisted localizations of breast lesions (with MICS-MIAS). Compatibility: GE Signa® (3X-LX) 1.5T, 1.0T, 0.5T MR scanners.
