About

Sarah Hesham is a pioneering researcher in the field of medical microrobotics, with a primary focus on developing minimally invasive techniques for treating vascular occlusions. Her major contributions center on the mechanical disruption of blood clots using magnetically actuated helical robots, offering a safer alternative to chemical thrombolysis by physically tearing fibrin networks rather than relying on clot-dissolving drugs. In her most cited work (84 citations), she demonstrated mechanical rubbing of blood clots under real-time ultrasound guidance, showcasing a novel approach to mitigate side effects associated with traditional lysis. Hesham further advanced the field by characterizing helical robot propulsion in whole blood and ex vivo rabbit aorta models, providing critical insights into their behavior under physiological flow conditions. Her research on the influence of mechanical rubbing on clot dissolution has also shed light on the mechanisms behind clot clearance, revealing how robot-tissue interactions facilitate the release of trapped blood components. Through these studies, Hesham has established herself as a key innovator in intravascular microrobotics, bridging the gap between laboratory concepts and clinical applications for safer, more effective treatments of thrombosis.
