InnerPulse, a medical device company pioneering technology for patients with cardiac rhythm disorders, has selected Abaqus finite element analysis (FEA) software from Dassault Systemes’ SIMULIA brand to assist in the development of its technology, designed in SolidWorks CAD software. 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. It has been estimated that SCD claims more than 7 million lives per year worldwide, and the overwhelming majority of those deaths are attributed to ventricular fibrillation, or rapid, uncoordinated contractions. InnerPulse has developed a percutaneous implantable defibrillator (PICD), which enables physicians to implant the life-saving defibrillators within a patient’s vasculature using a catheter procedure—making the procedure both minimally invasive and less expensive. Leveraging SolidWorks for design and the realistic simulation capabilities in Abaqus FEA software, the design engineers at InnerPulse are able to perform accurate analysis for concurrent device and tool design. “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, non-linear material capabilities in Abaqus allowed us to meet those requirements,” stated Cinnamon Larson, Ph.D., senior mechanical engineer, InnerPulse, Inc. “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.” For more information, visit SIMULIA.
