Abstract
High intensity focused ultrasound (HIFU) has the capability to induce hemostasis through rapid delivery of energy in the HIFU focal region. HIFU effectively induces hemostasis in small blood vessels; however, as vessel size increases, loss of heat to the flow increases until HIFU treatment is only minimally effective. A new method to enhance the HIFU‐induced heating effect was investigated. Single polymer fibers embedded in a heat‐sensitive phantom are shown to increase the size of HIFU‐induced lesions as compared to controls. Polymer meshes were then embedded in the phantom and the size of the HIFU‐induced lesions produced were compared with control lesions.
