Objectives To evaluate the long-term hemostatic efficacy of a new high-intensity collimated ultrasonic (HICU) applicator for open subhilar partial nephrectomy (PN) in the porcine model. Methods An applicator was designed with a planar 3.78-MHz HICU t

New curative and palliative treatments are needed to respond to the poor prognosis of esophageal cancer. The purpose of this study was to determine whether magnetic resonance imaging (MRI) and MR thermometry can be used to monitor the thermal ablatio

Intraluminal (within the alimentary tract) thermal surgery has been shown to be a useful therapeutic option when extracorporeal focused ultrasound applicators cannot be used since their beam may not reach the target site. If plane transducers are use

High intensity ultrasound has shown considerable ability to produce precise and deep thermal coagulation necrosis. Focused, cylindrical, spherical or plane transducers have been used to induce high temperatures in tissues to coagulate proteins and ki

International audience; In the high-intensity focused ultrasound (US), or HIFU, field, it is well-known that the cavitation effect can be used to induce lesions of larger volume. The principle is based on the increase in the equivalent attenuation co

Heat deposition by interstitial routes, especially with ultrasound-based instruments, is becoming a valuable therapeutic option for the treatments of sites, which are difficult to access from outside of the body. The active part of most interstitial

Recently, the instruments commonly used in urology have been organized in modules which are designed specially for use with a multi-purpose “urology table”. In order to fit into this design, the size of piezoelectric lithotripters will have to be

—Biliary cancer is very difficult to treat, mainly because of the advanced stage at which such tumours are detected and the low efficacy of systemic therapeutic modalities like radiotherapy. Palliative measures designed to clear the duct (either by

Extracorporeal HIFU techniques still cannot be used to treat tumours of the digestive tract, therefore an interstitial applicator has been developed to fill this gap. The object of the study was to validate the use of a plane ultrasonic transducer in
