No
The summary describes an image registration process based on hardware accessories (Matrices) and software, but there is no mention of AI, ML, or related concepts like training/test sets for such algorithms. The performance testing focuses on traditional accuracy metrics and comparison to a predicate device, not on AI/ML model performance.
No.
The device is described as a surgical device for image-guided surgery, providing image registration for intraoperatively acquired images. Its function is to assist in surgery by correlating patient data to the surgical environment, rather than treating a disease or condition itself.
No
This device is described as a surgical device for image-guided surgery that provides image registration to correlate intraoperatively acquired patient data with the surgical environment. Its function is to facilitate navigation during surgery, not to diagnose a condition or disease.
No
The device description explicitly states that it "consists of the software module Automatic Registration and hardware accessories." It also mentions "Matrices" which are described as reusable devices used for correlation and determining position, indicating a physical component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it is a "surgical device for image guided surgery." IVD devices are intended for use in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnosis, monitoring, or treatment. This device is used in vivo (within the body) during surgery.
- Device Description: The description reinforces its role in "image guided surgery" and as an "accessory to the Spine & Trauma navigation system." It facilitates the correlation of intraoperative images to the surgical environment, which is a surgical function, not an in vitro diagnostic function.
- Function: The core function is "image registration" to align intraoperative images with the surgical environment for navigation. This is a tool for guiding surgical procedures, not for analyzing biological samples.
The device's purpose is to assist the surgeon during a procedure by providing accurate spatial information based on imaging, which is a characteristic of surgical navigation systems, not IVD devices.

Non-Clinical Testing:

- Mean navigation accuracy: 0.93mm ●
- . 95th percentile of single navigation accuracy: 1.80mm
- Total number of navigation points n=228 .
Above listed non-clinical performance testing demonstrates the equivalence of the navigation registration accuracy of the subject device to the predicate device. It was performed in a simulated test environment which matches the test scenario of the cleared device, where a mean registration accuracy of 1.26mm was measured.
Minor modifications to the test setup were required due to the device change where a Registration Matrix within the scan volume is used for automatic registration instead of infrared scanner markers in combination with a navigation calibration as in the cleared device. The navigated region of interest and measurement methods were not changed since these parameters are not affected by the device change.
An additional performance test demonstrated that the registration method is also applicable for the cervical spine and navigation accuracy in this region is consistent with the initial results listed above.
Test results generated demonstrated better mean navigation accuracy and met stricter acceptance criteria (mean navigation accuracy:

Above listed non-clinical performance testing demonstrates the equivalence of the navigation registration accuracy of the subject device to the predicate device. It was performed in a simulated test environment which matches the test scenario of the cleared device, where a mean registration accuracy of 1.26mm was measured.
Minor modifications to the test setup were required due to the device change where a Registration Matrix within the scan volume is used for automatic registration instead of infrared scanner markers in combination with a navigation calibration as in the cleared device. The navigated region of interest and measurement methods were not changed since these parameters are not affected by the device change.
An additional performance test demonstrated that the registration method is also applicable for the cervical spine and navigation accuracy in this region is consistent with the initial results listed above.
