No
The description focuses on the physical characteristics and function of an MRI coil, with no mention of AI or ML for image processing or analysis.
No.
The device is described as a "diagnostic MR imaging coil" used for "obtaining diagnostic images," indicating it is for diagnosis rather than treatment.
Yes
The Intended Use / Indications for Use section explicitly states that the device is a "diagnostic MR imaging coil" and is "used for obtaining diagnostic images".
No
The device description clearly details a physical hardware component (a receive-only 2-channel diagnostic MR imaging coil) with specific dimensions and features, designed to interact with an MRI scanner. This is not a software-only device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to examine these samples outside of the body.
- Device Function: The Carotid Coil GE1.5T is a component of an MRI system. Its function is to receive radiofrequency signals emitted by the body during an MRI scan to create images. This process happens within the body (in vivo), not on samples taken from the body (in vitro).
- Intended Use: The intended use is to obtain diagnostic images of the carotid arteries in the region of the neck and lower cranium. This is a direct imaging procedure performed on the patient.
Therefore, based on the provided information, the Carotid Coil GE1.5T is a medical device used for in vivo diagnostic imaging, not an in vitro diagnostic device.

Device Description
The Carotid Coil GE1.5T is a receive-only 2-channel coil for operation at a magnetic field strength of 1.5T with the GE Twinspeed HDx system. The coil is a two-element coil consisting of two independent rectangular loops, each of approximate size 7 cm x 4.5 cm. Coupling of either coil element to the transmitted field is prevented through respective active blocking circuits.
The Carotid Coil GE1.5T is specially designed for MR imaging of the carotid arteries in the region of the neck and lower cranium. The coil provides optimum signal to noise ratio and coverage in the area of the carotid arteries, allowing high-resolution imaging, while the sensitive region of the coil covers an approximately 7 cm Field of View.

F. SAFETY AND EFFECTIVENESS
Tursiop Technologies, LLC complies with FDA's GMPs and is ISO 13485-certified for the design and manufacture of magnetic resonance imaging coils. The Carotid Coil GE1.5T complies with voluntary standards for safety/effectiveness (IEC 60601, UL 94, ISO 10993-1) all of which mandate that relevant components are tested to minimize hazards (electrical, mechanical, flammability, biocompatibility). The patient contacting surface is polycarbonate painted with biocompatible paint. ISO-mandated risk management practices have been utilized to assess potential risks throughout the device life cycle to mitigate unacceptable levels of risk by conducting risk assessment (FMEA) procedures.
Tursiop Technologies, LLC has conducted testing to establish the safety and effectiveness concerning the Carotid Coil GE1.5T. Side by side comparison testing was conducted with one of the predicate devices, GE 3-inch General Purpose Coil which demonstrated substantially equivalent performance. The Carotid Coll GE1.5T does not introduce any new potential safety risks and operates in a manner similar to the predicate devices.
G. SUBSTANTIAL EQUIVALENCE STATEMENT
The Carotid Coil GE1.5T is substantially equivalent to the GE 3-inch General Purpose Coil and the TT1 General Purpose Coil (K083434).
This opinion is based on the fact that comparing the Carotid Coil GE1.5T technological characteristics, coil architecture and operating principles with that of the predicate devices reveals that the devices comply with the same or equivalent standards and have the same or equivalent intended uses.
