Abstract

Braided wires are often used in medical devices, such as catheters, guidewires, and other interventional tools. These wires are designed to provide flexibility and strength, making them suitable for navigating through blood vessels and other anatomical structures during medical procedures. Abaqus FEA can be used to evaluate and optimize the structural performance and manufacturability of these critical components. This presentation will discus a novel approach to modeling the manufacture of a braided-wire embolization device. The embolization device manufacturing steps are simulated to capture wire compaction at the marker sites. The completed device is annealed then crushed between two rigid plates so that the structural stiffness can be assessed.

Presenter Bio

Senior Solution Consultant with 10 years of advanced nonlinear finite element analysis using Abaqus. PhD in biomedical engineering with a focus on patient specific modeling of aortic valves. I previously worked at Dassault Systèmes SIMULIA, Dearborn office, for several years, then Medtronic in the neurovascular space. In addition to traditional FEA, I develop advanced non-parametric optimizations using Tosca for rapid concept development as well as existing design modification to reach specific performance targets. I enjoy building strong client relationships through project work, training, and support in addition to workflow development.
