Simulation Best Practices for Medical Devices Design and Development
In recent years, the integration of in silico simulations has revolutionized medical device design and development. This blog explores the impact of utilizing Ansys simulation software in medical device product development.
The Impact of In Silico Clinical Trials
Two years post the release of a medical product, statistics reveal a significant reduction in the number of patients involved in clinical trials – a remarkable 256 fewer individuals. This reduction has resulted in a substantial cost-saving of $10 million. Moreover, over the same period, 10,000 patients were successfully treated with the product.
Engineering Goals and Requirements for Medical Devices
Safety, Time, and Cost – The Triad of Excellence
The engineering goals for medical devices focus on safety, time efficiency, and cost reduction. Achieving extreme reliability, shorter development cycles, and reduced clinical trials are crucial milestones. An emphasis on staff efficiency and patient safety is complemented by accelerated regulatory approval through adherence to ASTM and ISO standards.
The incorporation of in silico testing has seen a phenomenal increase – 10,000 more tests performed virtually, saving three months out of twelve in the development cycle and leading to a remarkable $10 million cost reduction for a single product. The multidisciplinary approach and adherence to EU-MDR and REACH standards have resulted in a Return on Investment (ROI) of over 500%.
