The description focuses on the physical components and function of an MRI head coil, with no mention of AI or ML for image processing or analysis.
No
Explanation: The device is explicitly described as a "diagnostic imaging device" used to produce images for diagnosis, not to treat a condition.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "intended to be used in conjunction with a Magnetic Resonance Scanner for the MR examination of the human brain" and "can also be used as a standard diagnostic examinations and fMRI." It further clarifies, "When used with magnetic resonance imaging systems, it is indicated for use as a diagnostic imaging device to produce transverse, sagittal, coronal and oblique images of the internal structures of the head. When interpreted by a trained physician, these images provide information that can be useful in determining diagnosis." The "Device Description" also repeatedly refers to it as a "diagnostic imaging device."
No
The device description clearly states it is a "head coil" which is a physical hardware component used in MRI systems. It also describes the coil's physical features (7 Channel Top Coil, 8 Channel Bottom Coil, rigid Coil Frame) and its manufacturing. While it interfaces with MRI software, the core device itself is hardware.
Based on the provided text, the Encompass™ 15 Channel Head Coil is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In vitro diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Encompass™ 15 Channel Head Coil is a component of a Magnetic Resonance Scanner. Its function is to receive the MR signal from the patient's head to produce images of the internal structures. It does not analyze biological specimens.
- Intended Use: The intended use clearly states it's for "MR examination of the human brain" and "to produce transverse, sagittal, coronal and oblique images of the internal structures of the head." This is an in vivo imaging process, not an in vitro diagnostic test.
Therefore, the Encompass™ 15 Channel Head Coil is a medical imaging device, specifically an accessory for an MRI system, and not an IVD.
N/A
Intended Use / Indications for Use
The Encompass™ 15 Channel Head Coil is intended to be used in conjunction with a Magnetic Resorance Scanner for the MR examination of the human brain just before, during, and at the end of brain surgery. The Encompass™ 15 Channel Head Coil can also be used as a standard diagnostic examinations and fMRI (Functional Magnetic Resonance Imaging). When used with magnetic resonance imaging systems, it is indicated for use as a diagnostic imaging device to produce transverse, sagittal, coronal and oblique images of the internal structures of the head. When interpreted by a trained physician, these images provide information that can be useful in determining diagnosis.

Substantial Equivalence Conclusions
The subject device, Encompass™ 15 Channel Head Coil, is optimized for use with the Encompass SRS Immobilization System for obtaining diagnostic MR images to be used to inform procedures which use MR imaging to guide interventional procedures and other treatments. While the predicate device, NORAS OR Head Coil 3T, is optimized for its usefulness in interventional surgery applications, both devices are head coils and the fundamental attributes of the subject device and the predicate device are the same.
The conclusions from the non-clinical data suggest that the subject device has the same fundamental technological characteristics with respect to the predicate device and exhibits an equivalent safety and performance profile as that of the predicate device.
Therefore, Qfix believes the Encompass™ 15 Channel Head Coil does not raise new questions of safety or effectiveness and, therefore, is substantially equivalent to the marketed predicate device.
