Simulating the Heating of Tissue with Ultrasonic Surgical Devices Using Multiphysics Modeling
Tune into this webinar featuring guest speaker Arlen Ward from System Insight Engineering to learn about the role of multiphysics simulation in the design of medical devices.
Ultrasonic surgical devices use mechanical vibrations transmitted down a waveguide to cut and coagulate tissue and seal blood vessels. When designing these medical devices, you can use the COMSOL Multiphysics(R) software to simulate the interaction between the device and the biological tissue and predict the resulting surgical effect. This saves prototyping time and results in a better performing and safer medical device.
Over the course of this webinar, we will present a model of the distal end of an ultrasonic surgical device and the interaction of the device with arterial tissue. Using the desired surgical effect on the artery as the performance criterion, we will demonstrate how COMSOL Multiphysics(R) is used to look at tissue variability and its impact on device design and performance.
