Finite Element Analysis Used in Catheter Design Greatly Reduces Development Costs
Written by Norman T. Neher, P.E. Analytical Engineering Services Introduction Developing new medical devices is both costly and time-consuming. Prototyping, bench testing, and redesign cycles can stretch development timelines and budgets. Finite Element Analysis (FEA) offers a way to break this cycle by enabling engineers to virtually test and refine designs early in the process. […]
Laser-cut catheter hypotube analysis
Using Finite Element Analysis to Evaluate Laser-Cut Hypo Tubes Introduction Medical device development is notoriously expensive and time-consuming. Every new design feature—whether in a catheter, stent, or surgical instrument—typically requires multiple cycles of prototyping and bench testing before it can be approved for use. Each cycle consumes materials, labor, and weeks (or […]
High-speed switch actuator analysis
High-speed switch/actuator ANSYS FEA was used to analyzed a complex switch/actuator assembly. This helped us understand the stresses during a sudden stop caused by an impact with the steel hard stop. See Figure 1. We compared this setup to one with a shock-absorbing stop, shown in Figure 6. If we can reduce the impact effects, […]
