Could a tiny leg patch replace bulky boots to stop deadly clots in the ICU?
NCT ID NCT05208216
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a small, wearable device called geko can help prevent dangerous blood clots in the legs of critically ill adults. The geko device uses mild electrical pulses to stimulate leg muscles, improving blood flow. Researchers compared it to standard compression boots (IPCs) in 40 ICU patients to see if it was practical to use. The goal was to find a simpler, potentially more effective way to protect very sick patients from blood clots.
