Product Concept Optimization
Structural Integrity offers scientists and device design engineers extensive finite element analysis (FEA) to accurately simulate, through computational modeling, the internal physics occurring within biological tissue when interacting with medical devices allowing for faster, more accurate, and safer device design by allowing a more comprehensive design process.
Predictive Modeling Software
Our advanced multi-physics modeling capabilities not only model the medical device physics, but the physics within the biological tissue when acted upon by the device. We also offer fracture mechanics and fatigue experience to help predict a device’s life cycle.
Experimental Testing Examples:
- Deformation, stresses and strains in the biological tube
- Fluid flow thru the biological tissue
- Temperature in the tissue
- Chemical reactions in the tissue
- Tissue Modeling
Using our advanced Non-linear FEA software, we offer clients the ability to simulate the device-tissue interactions, including impact on biological tissue, testing hundreds of design iterations in the time it would take to perform one experimental study.
A device design firm expressed interest in developing a model to inform and speed up the design process of their tissue fusion devices.
Goal: To develop a predictive FEA Model using minimal experimental work, they use the model to inform device design
Parametric studies of design inputs when pressure and temperature were applied, and hundreds of simulations were conduct in the time it takes to produce one prototype.
A client produces intravenous therapies to apply energy to arthroscopic plaque.
Goal: Needs a composite tube casing around tooling to be stiff enough to be pushed through an artery without crimping tools, but flexible enough to not damage the artery.
Including initial benchmarking of material (conducted in each physical iteration) numerous design iterations could be conducted in the time it takes to produce one prototype.

Simulation of the Thermo-Poromechanics of Biological Tissue During Fusion & Ablation
Dr. Douglas Fankell, our leading expert, expanded modeling capabilities to predict tissue deformation, internal tissue temperature and water flux occurring in the tissue when heated or pressured via external devices. These expansions were created from his doctoral studies, where he led the research efforts at the University of Colorado – Boulder to develop and characterize the multi-physical nature of the artery wall. The model development is used to predict the surgical outcomes of arterial tissue fusion devices.

Speeding Up The Device Design Process
The design iteration process – the design, production, and testing of physical prototypes – can be very expensive and time consuming. Our modeling capabilities reduce the number of design iterations and time by deploying the predictive modeling capabilities. Predictive modeling improves device design, reduces experimental testing resulting in a faster, more effective, finalized design.
