Design Devices Effectively
When attempting to simulate biological tissue, especially soft biological tissue, several challenges present themselves. Firstly, the mechanical structure of biological tissue is inherently complex. It is heterogeneous and often multi-phasic, meaning it is composed of several different materials and often has fluid flowing through and interacting with the solid tissue. Additionally, nearly all biological tissue acts non-linearly and undergoes large deformations. Thus, computational modeling efforts have been limited in scope and accuracy; however, great advancements in this arena are currently being made. Structural Integrity (SI), through utilizing its non-linear computational modeling capabilities and building on work conducted at the Advanced Medical Technologies Laboratory at the University of Colorado, has the ability to provide high fidelity simulations to evaluate the safety and performance of medical devices and procedures.
The Design Iteration Process
