#### Description and functioning of the device

SurgiCase Viewer provides functionality to allow visualization of 3D data and to perform measurements on these 3D data, which should allow a clinician to evaluate and communicate about treatment options.

SurgiCase Viewer is intended for use by people active in the medical sector. When used to review and validate treatment options, SurgiCase Viewer is intended to be used in conjunction with other diagnostic tools and expert clinical judgment.

The SurgiCase Viewer can be used by a medical device/service manufacturer/provider or hospital department to visualize 3D data during the manufacturing process of the product/service to the end-user who is ordering the device/service. This allows the end-user to evaluate and provide feedback on proposals or intermediate steps in the manufacturing of the device or service.

The SurgiCase Viewer is to be integrated with an online Medical Device Data System which is used to process the medical device or service and which is responsible for case management, user management, authorization, authentication, etc.

The data visualized in the SurgiCase Viewer is controlled by the medical device manufacturer using the SurgiCase Viewer in its process. The Device manufacturer will create the 3D data to be visualized to the end-user and export it to one of the dedicated formats supported by the SurgiCase Viewer. Each of these formats describe the 3D data in STL format with additional meta-data on the 3D models. The SurgiCase Viewer does not alter the 3D data it imports and its functioning is independent of the specific medical indication/situation or product/service it is used for. It's the responsibility of the Medical device company using the SurgiCase Viewer to comply with the applicable medical device regulations.

- Device architecture/technology: while the reference device Mimics Medical is a Windows based desktop solution, the subject device is a web application which can be used in different browsers and on different operating systems (however the underlying libraries used for image based operations are still the same in both products).

The above mentioned technological differences do not impact the safety and effectiveness of the subject device for the proposed intended use as is demonstrated by the verification and validation plan.

#### Performance Data

Software verification and validation were performed and documentation was provided following the "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". This includes verification against defined requirements, and validation against user needs with end-users.

The SurgiCase Viewer application has been validated for its intended use to determine substantial equivalence to the primary predicate device SurgiCase Viewer.

The medical images functionality was compared to the same functionality present in the secondary reference device Mimics. Both functionality produce the same results in:

- Contrast adjustments
- . Interactive image reslicing

{7}------------------------------------------------

- . 3D contour overlay on images
Measurement functionality on images was compared with already existing functionality on the 3D models and shown to provide correct results both on images and 3D.

#### Summary

The characteristics that determine the functionality and performance of the surgiCase Viewer are substantially equivalent to the devices cleared under K170419 and K183105. The non-clinical testing indicates that the subject device is as safe, as effective, and performs as well as the predicates.

From the substantial equivalence analysis we conclude that the intended use and technological characteristics of SurgiCase Viewer are substantially equivalent to a combination of the predicate device SurgiCase Viewer (K170419) and the reference device Mimics Medical (K183105). Based on the application of risk management and performance testing we conclude that SurgiCase Viewer is as safe and effective as its predicate and reference devices and does not raise any new issues related to safety and effectiveness compared to the predicate and reference devices, and has a comparable performance.
