Device Story

Mimics Medical is image processing software for importing, visualizing, and segmenting medical images (DICOM, RAW, TIFF, BMP, JPG). It transforms 2D medical imaging data into 3D digital models via semi-automatic and fully automatic segmentation algorithms. Users perform measurements, treatment planning, and surgical cut simulations on these models. Output files are exported for additive manufacturing (3D printing) or third-party analysis packages (e.g., Finite Element Analysis). Used in clinical settings by healthcare professionals for orthopedic, maxillofacial, and cardiovascular diagnostic support. The software facilitates the creation of physical anatomical replicas, aiding clinical decision-making and surgical preparation. It includes Python scripting capabilities for workflow automation.

Clinical Evidence

Bench testing only. Geometric accuracy of virtual models and 3D-printed physical replicas was assessed for cardiovascular, orthopedic, and maxillofacial applications. Results demonstrated that deviations were within predefined acceptance criteria, confirming performance equivalent to the predicate device.

Technological Characteristics

Software-based image processing system. Supports DICOM and standard image formats (RAW, TIFF, BMP, JPEG). Features include semi-automatic and fully automatic segmentation, 3D model calculation, measurement tools, and treatment planning modules. Modular architecture with Python scripting support. Operates on standard computing hardware. Software verification and validation conducted per FDA guidance.

Indications for Use

Indicated for use as an image processing and segmentation system for orthopedic, maxillofacial, and cardiovascular applications. Intended for clinicians to perform measurements, treatment planning, and generate 3D models for physical replica fabrication. Must be used with expert clinical judgment.

# Comparison of Technological Characteristics with the Predicate Device

The subject device Mimics Medical employs similar fundamental technologies as the predicate device. Technological similarities include:

- . Device functionality:
- O Image segmentation: The subject and predicate device share image segmentation functionalities.
- o Processing to output file: The subject and predicate device both generate an output file.
- O Measuring and planning: The subject and predicate device both have functionalities to perform measurements and pre-surgical planning.
- . Device design: The subject device originated from the same code base as the predicate device.

The following technological differences exist between the subject device and the predicate device:

- Imaging information: Whereas the predicate device is intended to import imaging information from a medical scanner such as CT or MRI scanner, the subject device is intended to import DICOM compliant types

{5}------------------------------------------------

of imaging information and also supports import of standard imaging formats (such as RAW, TIFF, BMP and ipeg format).

- . Device functionality: The subject device shares the technology and functionality of the predicate device. However, for the subject device, functionality was extended to improve the usability for the user.
Comparison of technological characteristics with the Reference Device (Mimics inPrint, K173619):

The subject device employs similar fundamental technologies as the reference device. Technological similarities include:

- Device functionality:
- Image segmentation: The subject and reference device share image segmentation O functionalities.
- Processing to output file: The subject and reference device both generate an output file. O
- . Device design: The subject device and reference device originate from the same code base (being the code base of the predicate device).

The following technological differences exist between the subject device and the reference device:

- . Imaging information: The reference device is intended to import DICOM imaging information from a medical scanner. The subject device is more generally intended to import imaging information of a medical scanner, allowing both DICOM compatible images and standard imaging formats (such as RAW, TIFF, BMP and jpeg format).
- Device functionality: The subject device shares the technology and functionality of the reference device, but is organized differently (graphical user interface of the software). The functionality of the predicate device is organized in a toolbox fashion, whereas the interface of the reference device specifically guides the user through a few predefined steps for obtaining a 3D printable output file.

# 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. Both end-user validation and bench testing were performed.

The geometric accuracy of virtual models created in the subject device Mimics Medical was assessed via bench testing. This was tested for cardiovascular, orthopedic and maxillofacial models. Accuracy of the virtual models was compared for the subject and predicate device. Deviations were within the acceptance criteria. This shows that for creating virtual models, Mimics Medical is substantially equivalent to the predicate device.

Apart from geometric accuracy of virtual models, also geometric accuracy of physical replicas (produced by 3D printing virtual models) was assessed. This was conducted for cardiovascular, orthopedic and maxillofacial models. The physical replicas were compared to the virtual models. Deviations were within the acceptance criteria, showing that virtual models can accurately be printed when using one of the compatible 3D printers.

In conclusion, all performance testing conducted device performance and substantial equivalence to the predicate device.

{6}------------------------------------------------

#### Summary

A comparison of intended use and technological characteristics combined with performance data demonstrates that Mimics Medical is substantially equivalent to the predicate device Mimics (K073468). Minor differences in intended use and technological characteristics exist, but performance data demonstrates that Mimics Medical is as safe and effective, and performs as well as the predicate device.
