Acoustic Levitation Puts a Pure Spin on Medicine Fabrication

July 16, 2014

Engineers from Argonne National Laboratory used multiphysics simulation and trial-and-error prototyping to optimize the effectiveness of an acoustic levitator for medical fabrication.

Understanding Drug-Eluting Stents at Boston Scientific

June 18, 2014

Stents open plaque-blocked arteries, but when an excessive amount of tissue grows over a bare metal arterial stent, it can cause the artery to narrow again in a process called restenosis.

Modeling High-Performance Liquid Chromatography

June 13, 2014

High-performance liquid chromatography involves mixing a solvent from a reservoir with a sample zone containing the analytes to be separated and then pumping the mixture into an injector.

Modeling Bone Strength Using Isotropic and Anisotropic Materials

December 20, 2013

The question of exactly how strong living bones are poses many important considerations for the medical industry. There is not currently a single-purpose device in the field to test bone strength. However, it is possible for researchers to get measurements of bone strength by modeling the entire makeup of the bone and using multiphysics simulation to perform stress and strain analyses. Simulating bone strength starts with a simple map of the external topology of the bone and then delves into […]

Optimizing Dialyzer Design Using Multiphysics Simulation

December 19, 2013

A while back, I had the opportunity to speak with Steven Conrad, a critical care physician at the Louisiana State University (LSU) Health Science Center in New Orleans. Not only is Dr. Conrad a physician as well as a professor at LSU, he’s also a biomedical engineer who uses finite element analysis (FEA) to conduct research on the design of dialyzers. Dr. Conrad uses COMSOL Multiphysics to gain a deeper understanding of the physics behind these devices, and to create […]

Modeling an Accurate Drug Delivery Device

August 22, 2013

There are many different routes through which drugs and other medications can be delivered into a patient’s body during treatment. These include topographical ointments, pills, vaporizers, and injection systems, among others. Many of these drug delivery systems require an enormous amount of precision when it comes to the location, timing, concentration, and amount of the drug to be administered. This is where simulation can be a big help, as it can allow for the modeling of each of these aspects […]

Equation-Based Modeling, a Custom Model of a Beating Heart

May 20, 2013

Equation-based modeling is one of the great strengths of COMSOL Multiphysics. The ability for you to easily access the equations describing the physics you are working with, and adding or manipulating them as you see fit, dramatically opens up the realm of possibilities that you can achieve through modeling and simulation. This is exemplified by the following custom model of a beating heart.

Gold Nanorods for Medical Treatment

January 10, 2013

Nanorods are synthetic nanoscale objects used in the area of nanotechnology. They can be synthesized from semiconducting materials or metals, such as gold. The applications of nanorods are many, ranging from display technologies and energy harvesting to cancer therapy.
