The summary describes a standard fluoroscopic x-ray system with image processing and storage capabilities, but there is no mention of AI or ML technologies being used for image analysis, interpretation, or any other function.
No
Explanation: The device is described as an image intensified, fluoroscopic x-ray system intended for imaging and diagnosis, not for treating conditions or diseases.
Yes
The device is described as an "image intensified, fluoroscopic x-ray system" used for "general examinations" and "imaging with radiography and/or fluoroscopy." It captures and processes images which are then stored, indicating its role in providing visual information for medical assessment, which is a core function of a diagnostic device.
No
The device description explicitly lists multiple hardware components including an X-ray generator, tube housing, flat panel detector, monitors, procedure table, and an X-ray cabinet.
Based on the provided information, the Dornier Nautilus is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's an image intensified, fluoroscopic x-ray system for general examinations in urology, gynecology, and other imaging procedures on patients. IVDs are used to examine specimens from the human body (like blood, urine, tissue) in vitro (outside the body).
- Device Description: The description details an X-ray system with components like an X-ray generator, tube housing, flat panel detector, monitors, and procedure table. These are all components of an imaging system used directly on a patient, not for analyzing samples.
- Input Imaging Modality: Fluoroscopic x-ray is an imaging modality used on living subjects, not for analyzing biological samples.
The device is a medical imaging system used for diagnostic purposes in vivo (within the living body), not in vitro.

Device Description
The Dornier Nautilus is an Image Intensified Fluoroscopic X-ray System with a flat panel image receptor system. The Nautilus consists of the following components: an X- ray generator and tube housing, flat panel detector, monitors and procedure table. An X-ray cabinet contains system elements such as the X-ray generator, power electronics for the imaging chain.
The Dornier Nautilus is a radiographic and fluoroscopy examination table with the X-ray tube housing mounted under the table on a fixed arm. A flat panel detector is mounted above the patient table. The flat panel used is a Varex model 4343DXV. These Varex 4343 series have been used in similar cleared devices (K192541). The Varex flat panel system uses Cesium Iodide as the image scintillator which is identical to that used in the predicate device. While the X-ray tube and detector are fixed in their positions relative to each other when the system is in use, the table top and X-ray/detector unit can be moved in a variety of planes to position the patient in the desired imaging position. The captured images are processed and can be stored in the users DICOM system.

Software Verification and Validation Testing:
The software used in the Nautilus has the identical functionality as in the predicate Genesis device. Documentation for a Moderate Level of Concern per FDA's Guidance Document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" issued on November 4, 2021 is also included as part of this submission.
Clinical testing is not necessary for the subject system Nautilus, based on the same basic technology as the predicate device and based on existing minor differences. Successful bench testing results should demonstrate substantial equivalence to the predicate device Genesis.
The results of the non-clinical performance standards testing support that the device can be used safely and effectively.
Substantial Equivalence/Conclusions
The Nautilus and the Genesis predicate device have intended use and indications. technological characteristics and principles of operation. The minor technological differences between the Nautilus and its predicate do not present different questions of safety or effectiveness. Furthermore, performance testing has demonstrated that the subject device is as safe and effective as the predicate device. In addition, the subject and predicate devices have similar principles of operation. Thus, the Nautilus is substantially equivalent to the predicate device
