Structural optimization is an important tool in the design process. The methods topology and shape optimization can be used to optimize the geometry of a device early in the product development process which can significantly reduce timelines. Reducing timelines with structural optimization will decease your costs significantly.
Linear structural analysis can be utilized for the design and performance evaluation of many medical devices. Certain medical devices such as balloon expandable and self-expanding (nitinol) stents, however, operate beyond the linear elastic range – i.e., plastic, superelastic, and hyperelastic. We can perform structural analysis of the devices with highly nonlinear materials. Also our experts have extensive experience with analyses involving geometrical nonlinearity such as contact between device components and between device and body parts (blood vessels and other).
Computational fluid dynamics (CFD) and fluid structure interaction (FSI) are utilized to assess the impact of blood flow or other types of body fluid on medical implants. We can leverage CFD and FSI to optimize device design, understand device performance, and troubleshoot device failures.
When there is time dependent movement of a device such as a guidewire tracking, dynamic analysis can be utilized for evaluating performance and optimum design of products.
Considering manufacturability of products during the device design stage is very important for avoiding significant timeline delays in the later stages of development.
Together with highly sophisticated material testing techniques, we can create models of biocompatible materials such as nitinol, stainless steel, cobalt chrome, titanium, and polymers which are a key component to achieve accurate results in finite element analysis.
