Biomedical Devices

Medical devices, especially those that are implanted in the human body, are some of the most complex and cutting-edge products available today. While they can save or improve the quality of a patient’s life, they also pose some of the biggest engineering challenges. And there is no room for error. Because these devices are surgically implanted, they must work correctly the first time, every time.

Even as organizations push the boundaries of medical applications, biomedical device developers anticipate a return on their sizeable investments — which includes design, prototyping, selection of materials, manufacturing and testing. ANSYS tools allow researchers to completely work through these issues before devices are implanted in patients. For example, simulation software can verify that a given device is an ideal fit for a specific patient, which can maximize surgical success in both short and long terms.

Another case in point case: Implantable cardiac rhythm management devices present myriad challenges for designers, who are working to create smaller devices that efficiently incorporate more features. Innovation in the complex cardiac environment, where temperature sensitivity is critical and reliability is imperative, requires technologies that provide the most precise measurements and functionality.

Modeling an organ as complex as the heart, and then designing a device in which electromagnetic fluxes occur in an area surrounded by blood, is a huge development challenge. ANSYS offers an integrated solution that enables designers to combine electromagnetic applications with complex multiphysics human models to make progress toward the best possible solutions.

Researchers working at the cutting edge of design can especially benefit from the advantages that ANSYS offers. One innovative example is a healthcare device that involves the use of electronic systems, communicating via radio frequency with a doctor’s computer. ANSYS software can help developers deal with problems such as finding ways to minimize the specific absorption rate (SAR), which requires complex thermo-electromagnetic interaction in a deformable structural environment.  Similarly, dramatic interference between signals sent by a defibrillator could be detected through simulation and avoided via a better design.

ANSYS comprehensive fluid dynamics capabilities for complicated physics and geometric modeling are the current industry standard. Other tools from ANSYS enable engineers to conduct detailed static, dynamic and thermal loading analysis. This breadth of multiphysics simulation tools is integrated into a simulation platform suite along with productivity enhancement tools including HPC, design exploration and data management to allow engineers to optimize their system designs across the various engineering disciplines. Altogether, the solutions from ANSYS help engineers to shorten the design cycle, meet stringent regulations and ensure safety standards.
