Simulation has always been an engineer’s best friend. Now, it’s becoming a regulatory ally, too. From the FDA to the EMA, agencies are increasingly open to in silico evidence to support design validation, safety assessment, and performance claims for medical devices. If you’re using COMSOL Multiphysics, you’re sitting on a mountain of valuable, submission-ready data, […]

Sterility is everything in the OR, and orthopedic implants are no exception. Whether it’s a hip prosthesis, spinal rod, or knee replacement, even a microscopic contaminant can lead to infection, inflammation, or rejection. Enter laser ablation: a precise, residue-free sterilization technique gaining traction for orthopedic components. And COMSOL, a leading simulation software, is playing a

Pacemakers have long been a marvel of medical engineering, but for decades, they had one fatal flaw: MRI machines. Strong magnetic fields and radiofrequency (RF) energy can heat leads, distort images, or cause dangerous malfunctions. That’s no longer acceptable. Today, engineers must design pacemakers to be MRI-safe, and simulation is their most powerful tool. The

Automatic dosing isn’t just about saving time; it’s about saving lives with unparalleled precision and safety. From insulin delivery to chemotherapy to hormone therapy, closed-loop systems are bringing precision medicine to the bedside and beyond. And it’s simulation that plays a crucial role in validating these systems, ensuring their safety and efficacy. Closed-Loop 101 In

Insulin pumps have come a long way from pager-sized clunkers. Today’s designs are slim, smart, and powered by microliters, not milliliters. At the core? Microfluidics, the epitome of precision in insulin delivery. Engineers using COMSOL Multiphysics are not just using simulation, they are leveraging it to perfect fluid dynamics, sensor integration, and closed-loop control in

In neonatal intensive care, every millimeter and every millisecond counts. That’s why the next generation of infant respiratory devices is going compact, connected, and computational. Wearables and liquid atomization technologies are revolutionizing neonatal care, and it’s the dedicated work of engineers utilizing COMSOL Multiphysics that is at the forefront of this transformation, inspiring a new

Chronic wounds cost the U.S. healthcare system more than $25 billion annually, and improper irrigation is a major culprit. However, the advent of simulation in medtech engineering has led to the development of cost-effective, safer, and more efficient wound care tools. These tools model fluid dynamics, spray patterns, and pump efficiency in silico, thereby reducing

Laser ablation is becoming the go-to technique for minimally invasive procedures ranging from tumor removal to cardiac arrhythmia correction. However, designing safe and precise ablation devices, especially those compatible with MRI, is no small feat. Here’s where the invaluable expertise of COMSOL engineers becomes crucial. Why Laser Ablation? Unlike traditional thermal or chemical ablation, laser

Rechargeable smartphones are great. Rechargeable hearts? Now that’s impressive. In situ battery charging for implantable medical devices, such as pacemakers, orthopedic stimulators, and neuroprosthetics, is rapidly evolving. And COMSOL engineers are on the front lines, using simulation to design devices that safely recharge inside the body without invasive procedures. The Challenge: Small Devices, Big Constraints
