NCT ID NCT07357285

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new device called the iNstroke 4F catheter, designed to remove blood clots from small blood vessels deep in the brain after a stroke. About 57 adults who have had a stroke within the past 24 hours will receive this treatment. The goal is to see if the catheter can safely restore blood flow and improve outcomes.
