Intended Use
The Ziehm 8000 mobile C-arm is intended for use in providing medical imaging for general populations. The device provides contactless fluoroscopic image capture, temporarily storing, and display of digital subtraction of cine loops during diagnostic, interventional and surgical procedures requiring X-ray imaging both inside and outside the operating room. Examples of clinical application may include cholangiography, endoscopic, urologic, lithotripsy, cardiac, orthopedic, vascular, pain management, angiographic, critical care, and emergency room fluoroscopy procedures. This device does not support direct radiographic film exposures and is not intended for use in performing mammography.
Device Story
Mobile C-arm X-ray system for intraoperative and diagnostic imaging; captures, stores, and displays fluoroscopic images and cine loops. Comprised of mobile stand with C-profile support, mono-block high-voltage generator, and Cesium-Iodide image intensifier. Operated by clinicians (physicians, technicians) via keyboard and touch-panel controls on mobile stand or monitor cart. Provides real-time visualization of anatomy to assist in pathology localization and surgical guidance. Features include virtual beam limiting, pre-filters for dose reduction, and removable anti-scatter grid. Output displayed on integrated high-resolution flat panel monitors. System supports DICOM networking for image storage and external peripheral connectivity. Benefits include improved maneuverability, reduced radiation dose, and enhanced image quality compared to predicate.
Clinical Evidence
No clinical data; bench testing only. Performance validated using anthropomorphic (PMMA) and anatomical simulation phantoms representing adult and pediatric populations. A board-certified radiologist assessed image sets, concluding that the Ziehm 8000 provides comparable image quality and reduced patient dosage relative to the predicate device.
Technological Characteristics
Mobile C-arm with mono-block X-ray generator (40-110 kV, 2.2 kW). Image receptor: 23cm Cesium-Iodide (CsI) intensifier. Connectivity: DICOM (wired/wireless), USB, DVD. Software: 12-bit grayscale, 1k x 1k display matrix. Standards: ANSI/AAMI ES60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 60601-2-43, IEC 60601-2-54, ISO 14971. Class I, Type B equipment.
Indications for Use
Indicated for general populations of any age, including infants, children, and adipose patients, requiring fluoroscopic imaging for diagnostic, interventional, and surgical procedures (e.g., cholangiography, urologic, cardiac, orthopedic, vascular, pain management). Contraindicated for direct radiographic film exposures and mammography.
Regulatory Classification
Identification

Dear Steve Seeman:
We have reviewed vour 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

| General Description: | The Ziehm 8000 mobile fluoroscopy system is |
comprised of a mobile stand with a C-Profile shaped support with both a mono-block high voltage generator assembly and Image Intensifier. These attach to either end of a C-Profile providing a fixed SID. The device performs 2D medical imaging using 4 axes of manual movement and one vertical axes of motorized movement. A user keyboard provides for concise user selectable anatomical programs and X-ray technique control. Integrated highresolution flat panel display monitors directly mounted on the monitor cart providing the clinician with a precise angle for visualization of live fluoroscopic images of the patient's anatomy. This visualization helps to localize regions of pathology for surgical procedures. The mobile stand supports a cable bound fluoroscopic footswitch. The optional interface panel of the Ziehm 8000 provides connection of peripheral devices such as external monitors, thermal video printers, and image storage devices (USB, DVD) and DICOM fixed wire and wireless network interfaces.

Performance bench testing included: Non-clinical imaqing and dose testing methods demonstrated the device capability to provide both reduced dose while maintaining image quality. Further in line with UCM089742- Premarket Assessment of Pediatric Medical Devices May 24, 2014 and UCM 302938- Pediatric Information for X-ray Imaging Device Premarket Notifications Nov 28, 2017. Non-clinical image and dose Lab testing, were employed. Anthropomorphic (PMMA material) phantoms and anatomical simulation phantoms were employed, image comparison sets taken were representative of both the adult and pediatric populations. A Radiologist performed an assessment of individual image sets. Radiologist conclusion, the image quality of the Ziehm 8000 results in a comparable patient care to the Predicate device (K051064). and fulfils the requirements as stated by the intended use. Therefore, Ziehm Imaging GmbH believes the Ziehm 8000 C-arm image quality, safety and effectiveness to be substantially equivalent to that of the predicate device Ziehm Quantum (K051064).
Summary of Clinical Test Data:
Ziehm 8000 mobile fluoroscopic C-arm system did not require live human clinical studies to support substantial equivalence in accordance with the FDA quidance Documents, UCM089742- Premarket Assessment of Pediatric Medical Devices May 24, 2014 and UCM 302938- Pediatric Information for X-ray Imaging Device Premarket Notifications Nov 28, 2017.
Therefore, Ziehm Imaging GmbH conducted an image comparison study employing the use of anthropomorphic phantoms in establishing substantial equivalence based on the modifications to the proposed device and the bench data taken. Evaluation of the individual images

arranged in image sets was conducted by a boardcertified Radiologist. His conclusion was the image quality combined with a reduced patient dosage will result in a comparable patient care to the Predicate device Ziehm Quantum (K051064). His comparison of the dose and images provided further evidence in addition to the laboratory performance data that the complete system works as intended and is substantially equivalent to the predicate device
Conclusion:
Ziehm Imaging GmbH considers the Ziehm 8000 to be as safe, as effective, and performs substantially equivalent to the predicate device Ziehm Quantum (K051064) in accordance with its labeling.
