In vitro ablation of cardiac valves using high-intensity focused ultrasound

Ultrasound in Medicine & Biology, 2005
The purpose of this study was to evaluate the possibility of using high-intensity focused ultrasound (US), or HIFU, to create lesions in cardiac valves in vitro. Calf mitral valves and aortic valves were examined. Focused US energy was applied with an operating frequency of 4.67 MHz at a nominal acoustic power of 58 W for 0.2, 0.3 and 0.4 s at 4-s ...

Extracorporeally induced ablation of renal tissue by high‐intensity focused ultrasound

BJU International, 2006
Authors from Germany describe the use of percutaneously applied high‐intensity focused ultrasound for non‐invasive tissue ablation. They found that the lessons they learned from the use of this technology in animals could be transferred to its use in humans, both of which are described.

Generation of uniform lesions in high intensity focused ultrasound ablation

Ultrasonics, 2013
High intensity focused ultrasound (HIFU) is emerging as an effective oncology treatment modality according to the clinical experience in the last decade. The temperature at the focus can reach over 65°C within seconds, denaturing cellular proteins and resulting in coagulative necrosis.

Non-Invasive Transcranial Brain Ablation with High-Intensity Focused Ultrasound

2014
The idea to ablate brain tissue with high-intensity focused ultrasound (HIFU) in a highly precise and localized manner is relatively old. For HIFU tissue ablation, ultrasound (US) waves are concentrated to a focal point. Due to US absorption, the focal area will be heated and consequently thermally destroyed.
