Minimally invasive intracardiac intervention using high intensity focused ultrasound

Optimal conditions for tissue perforation using high intensity focused ultrasound

“…Though erosion on the porcine atrial wall had been investigated using 8.8-cm focal length transducer [1], the focal length is not enough to treat the tissue lying deeper part in body. For this purpose we developed a device-set which has 15-cm focal length and have been investigating the conditions for tissue perforation [2]. We report about the position dependency of HIFU focus in the ventricle muscle.…”
