No
The description focuses on magnetic tracking technology and image registration, with no mention of AI or ML.
No.
The device is an image-guided navigation system that aids physicians in precisely locating anatomical structures during surgical procedures, not a therapeutic device directly treating a condition.
No
The device is described as an aid for precisely locating anatomical structures during image-guided navigation procedures and for tracking the real-time location of instrument tips relative to pre-acquired images. It assists in surgical procedures by providing guidance for accessing anatomical sites, rather than diagnosing a condition or disease.
No
The device description explicitly lists multiple hardware components (Navigation Console, Field Ring, Instrument Hub, Patient Tracker, Workstation, accessories) and describes a magnetic tracking technology involving hardware. The performance studies also include electrical tests and location accuracy tests that are clearly related to hardware performance.
Based on the provided information, the CARTO® ENT System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the system is for use during intranasal image-guided navigation procedures to aid in precisely locating anatomical structures. This is an in-vivo application, meaning it's used within the living body.
- Device Description: The description details a system that tracks the real-time location of surgical instruments relative to pre-acquired images (CT). This is a surgical navigation system, not a device that analyzes biological samples outside the body.
- Lack of IVD Characteristics: IVD devices are typically used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The CARTO® ENT System does not perform any such analysis of biological samples.
Therefore, the CARTO® ENT System falls under the category of a surgical navigation system, which is a type of medical device used during surgical procedures, not an in vitro diagnostic device.

Device Description
The CARTO® ENT System is intended to be used during intranasal and paranasal surgical procedures to help ENT physicians to track and display the real-time location of the tip of navigated instruments relative to pre-acquired reference images, such as CT. The CARTO® ENT device enables ENT physicians to access sphenoid, frontal, and maxillary sinuses by using the system magnetic tracking technology. The system incorporates a Navigation Console, Field Ring, Instrument Hub, Patient Tracker, Workstation and accessories. A magnetic field generated by the Field Ring induces a current in the magnetic sensor embedded in the tip of the flexible navigated tool, which helps to accurately calculate the tool tip position. A CT image is imported and registered to the patient coordinates and a tool tip icon is displayed on top of the registered image, indicating the position of the tool in reference to the patient anatomy. A Patient Tracker is fixed to the patient forehead to compensate for the head movement during the navigation procedure.

Summary of Performance Studies
Non-Clinical Performance Data: The CARTO® ENT System was tested to ensure that it functions in accordance with the system design specifications related to substantial equivalence in terms of device safety and effectiveness. The following nonclinical tests were performed:
- Proof of Design electrical tests, to verify all hardware modules perform within specifications.
- Location Accuracy tests, where the CARTO® ENT System electromagnetic locations were compared to the locations provided by a, very accurate robot system over the entire navigation volume, to verify the system precision claim.
- Software functional tests, covering the complete system functionality, and including error handling, usability and time performance (latency).
- Safety and EMC tests were performed by a nationally recognized testing laboratory to verify compliance with safety and EMC standards for medical devices.
- Simulated use accuracy test, in which a complete CT image registration and instrument navigation workflow was performed, to verify the overall accuracy of the system.
- Pre-clinical (cadaver) tests were designed to mimic surgical procedures using the CARTO® ENT System in a simulated clinical environment, to assess the execution of a complete sinuplasty procedure workflow and to qualitatively estimate the system clinical accuracy.
The results of the above tests support the safety of the device and demonstrate that the CARTO® ENT System perform as intended in the specified use conditions. The tests also demonstrate that the device performs comparably to the predicate device for the same intended use.
Clinical Performance Data: Clinical data was not necessary for the CARTO® ENT System. The performance data demonstrated that the device performs as intended.

The primary difference between the Fiagon Navigation System and CARTO® ENT Navigation System is that on top of manual registration supported by the Fiagon system, where the physician manually selects points and surfaces to be registered, the CARTO® ENT System also supports a force sensing registration mode, where points and surfaces are automatic acquired when adequate pressure is applied with the registration probe on the patient face. Since the physician is instructed to verify the quality of the registration, this addition does not raise new issues of safety and effectiveness.
