The description focuses on image-guided surgery using electromagnetic tracking and registration, with no mention of AI or ML algorithms for image processing, analysis, or decision support.
No
Explanation: The device is an image-guided surgery system used for navigation during ENT procedures, not for treating any medical condition directly. Its purpose is to assist the surgeon, not to provide therapy itself.
No
Explanation: The device is described as a computer-assisted image-guided surgery system that displays the position of navigated instruments on a model of the patient's anatomy based on preoperative images. Its stated purpose is for aiding in surgical procedures, not for diagnosing medical conditions.
No
The device description explicitly states that the system comprises a computer platform, software, patient trackers, pointers and suction tubes, instrument trackers, and a dedicated calibration body, indicating it includes hardware components beyond just software.
Based on the provided information, the Stryker ENT Navigation System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Stryker ENT Navigation System Function: The description clearly states that the system is a "computer-assisted image-guided surgery system." It uses pre-operative images (CT or MRI) of the patient's anatomy and electromagnetic tracking to display the position of surgical instruments during procedures.
- Intended Use: The intended use is for "stereotactic surgery" in ENT procedures, where the system helps guide the surgeon based on the patient's anatomy. This is an in-vivo application, meaning it is used directly on or within the living patient.
The system's purpose is to assist surgeons during procedures by providing real-time positional information relative to the patient's anatomy, not to analyze biological samples outside the body.

Device Description
The Stryker ENT Navigation System is a computer-assisted image-guided surgery system. The system displays the position of navigated instruments on a model of the patient's anatomy based on preoperative images (CT or MRI) using electromagnetic tracking technology. The position of the instruments and the patient are localized within an electromagnetic field produced by a field generator. The navigation of instruments relative to the patient's anatomy is established via registration of the patient's anatomy to the preoperative images via anatomical landmarks, or surface matching. The position of navigated instruments is then displayed with respect to preoperative images.
The system comprises a computer platform, the software, patient trackers, pointers and suction tubes, instrument trackers, and a dedicated calibration body.
This submission is about the new version 3.6 of the Scopis software application, and the updated computer platform called Electromagnetic Navigation Unit with the new operating system version 3.6.A.

The purpose of this Traditional 510(k) Submission is to gain clearance for the new version of the Scopis software variants and the updated Electromagnetic Navigation Unit as parts of the Stryker ENT Navigation System.
The initial clearance of this navigation system was achieved via K161491 in 2017 by Scopis GmbH. Scopis GmbH was acquired by Stryker in November 2017. In July 2018, the legal manufacturer for the devices was changed to Stryker Leibinger GmbH & Co. KG. Since October 2019, the devices have also been physically manufactured in Freiburg under the Stryker Leibinger Quality Management System. The 510(k) ownership was also transferred.
As part of the post-acquisition integration the Scopis name of the system was changed from Scopis Hybrid Navigation System to Stryker ENT Navigation System.
The Scopis software applications were most recently cleared under K193118 in 2020. The computer platform called Electromagnetic Navigation Unit was cleared within the first submission for the system with K161491.
Device Description
The Stryker ENT Navigation System is a computer-assisted image-guided surgery system. The system displays the position of navigated instruments on a model of the patient's anatomy based on preoperative images (CT or MRI) using electromagnetic tracking technology. The position of the instruments and the patient are localized within an electromagnetic field produced by a field generator. The navigation of instruments relative to the patient's anatomy is established via registration of the patient's anatomy to the preoperative images via anatomical landmarks, or surface matching. The position of navigated instruments is then displayed with respect to preoperative images.
The system comprises a computer platform, the software, patient trackers, pointers and suction tubes, instrument trackers, and a dedicated calibration body.
This submission is about the new version 3.6 of the Scopis software application, and the updated computer platform called Electromagnetic Navigation Unit with the new operating system version 3.6.A.
Electromagnetic Navigation Unit
The Electromagnetic Navigation Unit serves as platform of the Stryker ENT Navigation System. This is the computer platform where the navigation software is installed on, and where the main components required for navigation are connected to, like Field Generator or electromagnetic instruments.
Optionally, the Electromagnetic Navigation Unit allows to display the output of external endoscopic imaging devices from Stryker or other manufacturers. Instrument trackers allow for navigation of corresponding endoscope optics. A dedicated calibration body is utilized to calibrate endoscopes and enable Augmented Reality overlay of endoscopic video images.

Scopis Software Application
The software application provides the functionality necessary to import the patient image data sets, build the image-based model of the anatomy, plan a surgical procedure, and display location of navigated instruments relative to the model of the anatomy.
There are two navigation software variants: Scopis ENT Software and Scopis ENT Software with TGS. In comparison to Scopis ENT Software, Scopis ENT Software with TGS offers the ability to create more advanced surgical plans such as target paths to anatomy and display these during navigation. Both Scopis navigations software variants are installed on the Electromagnetic Navigation Unit.
In addition, there will be one designated planning software called Scopis Planning Software. This variant offers identical functionality for creation of advanced surgical plans like Scopis ENT Software with TGS but does not include any navigation functionality. This software is intended to be used on a planning system, like a personal computer of the surgeon, to prepare the application of one of the navigation software variants. Accordingly, after planning the data are to be transferred to the Electromagnetic Navigation Unit for surgical navigation with one of the navigation software variants.
Intended Use
The Scopis ENT Software is intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures together with the Stryker ENT Navigation System. The software application is indicated for any medical condition in which the use of computerassisted surgery may be appropriate
