No
The description focuses on electromagnetic tracking and image-to-patient registration based on autodetection of x-ray markers, without mentioning AI or ML algorithms for image analysis, navigation, or other functions.
No
The device is described as an image-guided surgery system intended to display the position and orientation of surgical instruments relative to anatomy, which is a navigational aid rather than a device that directly treats a medical condition.
No
The device is an image-guided surgery system intended to continuously display the position and orientation of surgical instruments relative to the anatomy in medical image data during orthopedic procedures. It is used for guiding surgical interventions, not for diagnosing medical conditions.
No
The device description explicitly mentions hardware components like electromagnetic tracking technology, sensors, a field generator, and a MapperBridge device, and the performance studies include testing for electrical safety, electromagnetic compliance, and accuracy bench testing for instrument probes and localizers, all of which are related to hardware.
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 (like blood, urine, or tissue) to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- RIWOtrack Navigation System Function: The RIWOtrack Navigation System is a surgical navigation system. It uses electromagnetic tracking and imaging data (fluoroscopy) to guide surgical instruments during procedures. It does not analyze biological samples from the patient.
- Intended Use: The intended use clearly states it's for "continuously display[ing] the position and orientation of RIWOspine surgical instruments relative to the anatomy in medical image data." This is a surgical guidance function, not an in vitro diagnostic function.
The device is a surgical tool that aids in the execution of a procedure, not a diagnostic test performed on a sample.

Intended Use / Indications for Use
The RIWOtrack Navigation System is intended to continuously display the position and orientation of RIWOspine surgical instruments relative to the anatomy in medical image data in either open or minimal invasive orthopedic procedures. The use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as the spine or pelvis, can be identified relative to images of the anatomy. This can include spinal procedures, where the target point for the access to the area of interest, is a rigid landmark, such as:
Transforaminal procedure
Interlaminar procedure

Device Description
The RIWOtrack Navigation System is an image guided surgery system, visualizing instrument positions on intraoperative fluoroscopy images (AP and LAT) utilizing electromagnetic tracking technology. The positions of the instrument and of the patient localizer, both equipped with sensors, are localized within an electromagnetic field, generated by a field generator, called navigation sensor. The principle of navigation is based on electromagnetic spatial measuring of localizer element in a generated electromagnetic field. The display of navigation information requires an image-to-patient registration procedure. During registration procedure, the Navigation System determines the coordinate transformation between the physical position of the patient and the position of the patient in intraoperative scans by means of autodetection of x-ray marker of a device called MapperBridge. Thereafter, the spatial position of the instrument is displayed superimposed to the image data. The navigation information is updated with a rate of 15 to 45 Hz.

Dear Dirk Mucha:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.
