Real anatomy, real compliance, real results: custom models for each stage of product development and beyond.



Accelerate your device development process by testing your devices in clinically relevant anatomical models. Our process goes beyond simple geometric accuracy; we can tune model compliance, puncture force, vessel straightening, and other properties to meet your testing needs. In close collaboration with physicians, we select, analyze, design, validate, and manufacture anatomical models, all under one roof.

Model design capabilities, available à la carte or as a comprehensive package:

Design starts with the patients. We facilitate medical record reviews for both retrospective and prospective evaluations, securing the appropriate Institutional Review Board (IRB) approvals as required. 

Specific anatomical features, disease states, and populations of interest can be specified to drive design decisions and specifications, identify relevant anatomy for testing, and provide the foundation for formal justification of design and testing targets chosen.

Next Phase

We employ 510(k) cleared segmentation workflows to transform patient imaging into editable 3D files, ensuring an accurate and streamlined process. We conduct anatomical segmentation using imaging provided by the client or the JI.

Next Phase

If needed, we provide comprehensive anatomical analysis on vascular or related features using segmented patient imaging. This analysis is documented in a formal design justification report which serves as a statistical justification for the model design’s clinical relevance and degree of clinical challenge.

This analysis often includes:

    • Pathway length
    • Vessel diameter
    • Radius of curvature
    • Angle of curvature
    • Cross-sectional area


Next Phase

We can customize model geometry based on a single patient scan or incorporate engineered features and anatomical sections combined from multiple patient scans. Customization does not end at geometry. We can tune the material properties to achieve realistic vessel compliance or reproduce feature hardness from subcutaneous fat to bone. 

These capabilities can be employed to simulate various disease states, such as vessel calcifications, chronic total occlusions, and tumors; providing appropriate and relevant challenges for device design and testing.

Next Phase

We design and manufacture all models within our Quality Management System. We also offer a comprehensive qualification report justifying the clinical relevance of the model to support device testing and regulatory submissions.

Justification reports may include:

      • Physician validation in simulated use conditions 
      • Geometry verification and/or compliance to applicable regulatory guidance
      • Material property verification
      • Physiologic verification (volumetric flow, pressure, and temperature)
      • Vessel lubricity & transparency
