Indications for Use
The Sentinelle Vanguard Breast MRI Auxiliary Table/Tabletop with 8/16 Channel Coil Array for GE 1.5T/3T MRI Systems is an open, receive only breast coil designed to provide magnetic resonance images of breast anatomy when used in conjunction with a Magnetic Resonance Scanner. These images can be interpreted by a trained physician. When used with a sterile plate, the device permits access to the breast anatomy for biopsy and localization procedures that can be performed by a trained physician.
Device Story
Vanguard Breast MRI Auxiliary Table/Tabletop is a receive-only phased array coil system for 1.5T/3T GE MRI scanners. Device supports patient, immobilizes breast via compression plates, and provides access for interventional guidance (e.g., biopsy). Input: RF emissions from nuclei excited by MRI scanner. Transformation: Passive collection of RF signals via 8 or 16-channel phased array coil elements. Output: Enhanced signal-to-noise ratio (SNR) and image resolution for MRI reconstruction. Used in clinical imaging settings by radiologists/physicians. Compression system includes interchangeable fenestrated plates for needle access. Benefits: Improved image detail and faster acquisition via parallel imaging; facilitates minimally invasive breast interventions.
Clinical Evidence
No clinical data provided. Substantial equivalence is based on bench testing and technological comparison to the predicate device.
Technological Characteristics
Receive-only phased array MRI coil; 8 or 16-channel configurations. Rigid, fluid-resistant, fire-retardant housing. Includes table base/tabletop, compression frames, and fenestrated plates. Compatible with GE 1.5T/3T MRI systems. Passive RF signal collection. No active software algorithms; hardware-based signal acquisition.
Indications for Use
Indicated for patients requiring breast MRI imaging and interventional procedures (biopsy/localization). Used by trained physicians to obtain breast anatomy images and provide access for interventional guidance.
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.

#### V. Device Description
The Vanguard Breast MRI Auxiliary Table/Tabletop with 8/16 Channel Coil Array for GE
1.5T/3T MRI Systems is a receive-only MRI imaging coil and interventional system for the breast anatomy. The system consists of a table base and/or a tabletop supports the patient, the imaging coils and means for modest compression/immobilization of the breast, as well as a means of enabling interventional device guidance. The table base (optional) is used to support and transport the tabletop.
The tabletop, like other breast coils provides an aperture to admit the breasts. A corresponding aperture in the table base maximizes physician access to the breast(s) when the tabletop is at the home position. This table aperture is useful for guidance of interventional devices (such as biopsy needles), especially when it is desired to perform a biopsy from a medial approach.

The tabletop's compression system facilitates immobilization of the breast for imaging and interventional procedures and serves to hold the individual imaging coils in proximity to the breast(s).
Compression plates provided with the system are held in compression frames which may be positioned in the left-right and anterior-posterior directions and fixed in place to gently immobilize one or both breasts for interventional procedures.
When performing a stereotactic interventional procedure (such as biopsy or wire localization), one or more compression plates may be interchanged for a sterile, single use, disposable fenestrated plate cleared under FDA 510(k) number: K060873. The fenestrated plate has apertures that permit the physician to access the breast for intervention, while minimizing tissue motion.
When performing biopsy and/or imaging of a single breast, the system may be used with two compression plates immobilizing that breast. The contralateral breast support prevents the contralateral breast from interfering with medial-approach interventions.
When imaging both breasts, a medial coil element is used between the breasts in conjunction with two lateral coils. The tabletop's receive-only coil system acts to passively collect RF emissions from the nuclei excited by the MRI. The function of the tabletop is substantially equivalent to predicate devices used for breast MRI maging and intervention, including our legally marketed device 510(K) Number: K060873.
The Vanguard phased array coil set consists of 8 or 16 RF coil elements in a phased array design. The 16 channel coil array may be interchanged with a 10 or 2-channel coil array. The coil elements and electronics are enclosed in a rigid housing that is resistant to fluid ingress and is fire retardant. The coils are positioned close to the patient's breast during imaging. This receive-only coil is designed to give an improved signal-to-noise ratio, image resolution and image acquisition over that of a standard body coil.
