The description focuses on optical tracking and automatic image transfer and registration based on positional data, with no mention of AI/ML techniques for image analysis, processing, or decision-making.
No
The device is an accessory to an image-guided surgery system and is used to transfer and register 3D images. It does not directly treat or diagnose a disease or condition.
No
The device is described as an accessory that enables the transfer and registration of 3D images from a C-arm to a navigation system for image-guided surgery. Its function is to make the C-arm visible to the navigation system and facilitate image transfer and registration, not to diagnose medical conditions or interpret clinical images.
No
The device description explicitly mentions "optical reflective markers in the tracker housings" and "magnetic mounting sockets on the housing," which are physical hardware components. The device is an "integration interface (tracker and C-Arm)" and includes a "tracker assembly" with optical markers.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Function: The Ziehm RFD 3D Interface is an accessory that facilitates the transfer and registration of imaging data (three-dimensional images from a C-arm) for use in image-guided surgery. It interacts with the C-arm and the navigation system, not with biological specimens.
- Intended Use: The intended use is for image-guided spinal surgery, which is a clinical procedure performed on the patient, not a laboratory test on a specimen.
The device's function is to integrate imaging equipment with a surgical navigation system to aid in surgical procedures. This falls under the category of medical devices used for imaging and surgical guidance, not in vitro diagnostics.

Device Description
The Ziehm RFD 3D Tracker works by making the Ziehm RFD 3D C-arm visible to the StealthStation™ Navigation Systems. The optical reflective markers in the tracker housings interact with the camera and software to identify the position and orientation of the C-arm detector in three-dimensional space.
When optical markers are inserted into the magnetic mounting sockets on the housing, the combination is then referred to as the tracker assembly. The optical markers interact with the camera and software to identify the position and orientation of the C-arm detector in three-dimensional space.
The integration interface (tracker and C-Arm) enables automatic transfer and registration of images received from Ziehm RFD 3D system within StealthStation™ system, specifically within StealthStation™ Spine software (K170011).
To enable automatic image registration, at the beginning of each scan the StealthStation™ camera captures the position of an optical tracker attached to the C-arm in relation to the patient reference frame. Upon image acquisition, the images from Ziehm RFD 3D system and associated calibration information are automatically transferred to the StealthStation™ system as a DICOM volume over an Ethernet cable. Upon completion of the DICOM volume transfer, the StealthStation™ software automatically registers the image relative to the patient reference frame.

Dear Nicole Zimmerman:
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 (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. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
