Thursday, July 16 – 9:00 AM EDT

In the medical device industry, performance evaluation of designs routinely includes animal testing, benchtop experiments, and human clinical trials. In the cardiovascular industry, computational modeling tools are being increasingly used to improve the understanding of device performance and accelerate development.  

The FDA is currently sponsoring workshops to lay the groundwork for the effective use of simulation tools in medical device development and the regulatory submissions process. In particular, nonlinear finite element (FEA) techniques, available in Abaqus FEA, enables device designers to realistically simulate the mechanical behavior (stress-strain response) of implants accounting for complex material behavior, the manufacturing process, and the deployed configuration of these devices, including soft tissue interaction.

Attend this free one-hour webinar to discover how Xiao-Yan Gong, of Medical Implants Mechanics, LLC, is using Abaqus FEA from SIMULIA to help its clients improve their device designs and obtain regulatory approvals. You will also learn how you can leverage realistic simulation solutions from SIMULIA to perform robust design studies in various stages of your development process.  

Attend and Learn How To:

• Model and analyze complex material behavior, such as Nitinol, in your designs.
• Account for the manufacturing and deployment processes
• Simulate multiple loading conditions simultaneously
• Evaluate the Fatigue Safety Factor (FSF) of your device
• Effectively use FEA results for the design approval submission process

Who Should Attend:

All designers, engineers, engineering managers, and directors who would like to learn about the value of nonlinear FEA using Abaqus for medical device development and leverage the experience of a distinguished medical device developer.

About the Presenters:

Xiao-Yan Gong, President and CEO, Medical Implants Mechanics, LLC.

Xiao-Yan Gong received his Ph.D. in Mechanical Properties of Materials from UC, Santa Barbara. Dr. Gong is currently President of Medical Implant Mechanics LLC, addressing the increasing demand for mechanical analysis in the medical device and implant industry. Since August 2006, MIM has established a solid record of helping its clients improve their designs and obtain regulatory approvals. He also served as the group leader on “Fatigue to Fracture and Beyond” for the ASTM F04.30.06 Task Group on Medical and Surgical Materials and Devices, Cardiovascular Standards Subcommittee. Dr. Gong has more than 23 years of experience in Finite Element Analysis with concentrations in both structural and fluid dynamics. He started working in the medical device and implant industry in June 1998 as a Senior Design Analyst for Carbomedics Inc., a prosthetic heart valve manufacturer in Austin, Texas, where he worked closely with design engineers. This experience led him to recognize the value of numerical analysis in the early stages of product design, and he made nonlinear finite element analysis in flexible heart valve design a routine practice in the company. Prior to establishing Medical Implant Mechanics, Dr. Gong was a Principal Engineer for Nitinol Devices and Components, a Johnson & Johnson Company, where he focused on nonlinear Finite Element Analysis on Nitinol-based implantable devices, established a peripheral stent durability program, and conducted Nitinol fatigue research.
