The device is used for preoperative planning and analysis of medical images, not for treating or diagnosing a disease or condition.
No
The device is intended for preoperative planning and analysis of data and images for surgical procedures. It does not diagnose diseases or conditions.
Yes
The device description explicitly states it is a "PC-based software application" that imports medical images and performs analysis. There is no mention of accompanying hardware components that are part of the regulated device.
Based on the provided information, 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, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The MeVis LiverAnalyzer / LiverViewer Software™ analyzes medical images (CT, MRI) to assist in preoperative planning for liver surgery. It performs tasks like segmentation and volume calculations based on image data, not on biological samples.
- Intended Use: The intended use is clearly stated as "preoperative planning in liver surgery," which is a clinical application based on imaging, not laboratory testing of biological samples.
- Device Description: The description focuses on image processing and analysis of DICOM images, not on handling or analyzing biological specimens.
Therefore, the device falls under the category of medical imaging software used for surgical planning, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The MeVis LiverAnalyzer / LiverViewer Software™ device is intended for preoperative planning in liver surgery. The device is used to analyze data and to display image analysis and risk analysis results for the preoperative planning in liver surgery, e.g. organ segmentation, tumor segmentation, segmentation of intrahepatic vessels as well as the approximation of vascular territories. Preoperative evaluation of specific surgery strategies is supported by the feature to interactively define virtual resections splitting the liver or to calculate safetymargins around lesions identifying affected vascular branches and vascular territories supplied or drained by these branches.

Device Description
MeVis LiverAnalyser / LiverViewer Software™ is a PC-based software application that imports medical images (i.e. CT, MRI modalities) in a DICOM format. The MeVis-LiverAnalyser is used to analyze data for preoperative planning in liver surgery. The MeVis-LiverAnalyzer contains dedicated methods for organ segmentation, tumor segmentation, and segmentation of intrahepatic vasculature as well as for the approximation of vascular territories. While using the MeVis-LiverAnalyser a number of masks are produced to merge voxels into sets. Each of this set is meant to represent a specific anatomical entity. All volumes calculated by the MeVis-LiverAnalyzer are given directly by the number of voxels in one of these sets multiplied by the voxel volume. No direct measure of anatomical entities is performed.

§ 892.2050 Medical image management and processing system.
(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)

Image /page/1/Picture/0 description: The image shows a logo for MeVis, which appears to be a company or organization. The logo features the name "MeVis" in a stylized font, with the "Me" part larger and bolder than the "Vis" part. Below the name, there is some smaller text, which is difficult to read due to the image quality. Further down, there is more text that reads "Centrum fur Medizinische Diagnosesysteme und Visualisierung GmbH".
Indications for Use: 21 CFR 807 92(a)(5)
