A new device offers a better way to detect blood clots, especially in pediatric patients, researchers report.

Unlike what a biology textbook may show, blood vessels are not straight cylinders. They are tortuous, meaning they have complex curves, spirals, and bends. When the blood reaches these curves, it makes changes to its fluid mechanics and interactions with the vessel wall.

In a healthy person, these changes are in harmony with the tortuous microenvironment, but when diseased, these environments can lead to complex flow conditions that activate proteins and cells that eventually lead to blood clots.

The fact that medical devices
