Sudden cardiac death (SCD) remains a major threat despite advances in medication and other treatments. According to the Sudden Cardiac Arrest Association, approximately one American life is lost every two minutes and it has been estimated that SCD claims more than 7,000,000 lives per year worldwide–the overwhelming majority of those deaths are caused by ventricular fibrillation, or rapid, uncoordinated contractions.
InnerPulse has developed a percutaneous implantable defibrillator (PICD) that enables physicians to implant the life-saving defibrillators within a patient’s vasculature using a catheter procedure, making the procedure minimally invasive and less expensive. Leveraging SolidWorks for design and the realistic simulation capabilities in Abaqus FEA software, the design engineers at InnerPulse were able to perform accurate analysis for concurrent device and tool design, saving valuable development time and costs.
“It was important for us to be able to model the way Nitinol material in our PICD anchoring technology will behave throughout the complete manufacturing process. The powerful nonlinear material capabilities in Abaqus allowed us to meet those requirements,” stated Cinnamon Larson, Ph.D., senior mechanical engineer, InnerPulse. “By using the Abaqus/CAE Associative Interface for SolidWorks, we were able to easily synchronize our SolidWorks design model and the Abaqus simulation model throughout the development process. This not only enhances collaboration between our designers and analysis experts, but it also improves our productivity and reduces design time significantly.”
“SIMULIA has a specific focus on providing realistic simulation solutions that meet the demands of the medical device industry,” stated Ken Short, VP, strategy and marketing, SIMULIA, Dassault Systèmes. “We are committed to developing innovative technology to meet our customers’ needs for both devices and biological tissue simulation.”
