Intended Use

To be used in conjunction with a Magnetic Resonance Scanner to produce diagnostic images of the elbow that can be interpreted by a trained physician.

Device Story

EXS-63 Small Extremity Array Coil; accessory for Magnetic Resonance (MR) scanners. Device functions as radiofrequency (RF) receiver coil to capture MR signals from elbow anatomy. Signals processed by MR scanner to generate diagnostic images for physician interpretation. Used in clinical imaging environments by trained radiology staff. Provides high-resolution imaging of elbow structures to assist in clinical diagnosis.

Clinical Evidence

Bench testing only.

Technological Characteristics

RF receiver coil; small extremity array configuration; designed for elbow imaging; compatible with standard MR scanner interfaces.

Indications for Use

Indicated for patients requiring diagnostic magnetic resonance imaging of the elbow.

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.
