The aim of this study was to compare ultrasonographic findings on tape position, angulation and mobility following three surgical anti-incontinence procedures (trans-obturator tape (TOT), tension-free vaginal tape (TVT), tension-free vaginal tape obturator (TVT-O)) and to correlate these data with clinical signs of cures and failures and de novo voiding(More)
Laparoscopic surgery takes place in a closed environment, the peritoneal cavity distended by the pneumoperitoneum whose parameters, such as pressure, composition, humidity and temperature of the gas, may be changed and adapted to influence the intra and postoperative surgical processes. Such changes were impossible in the "open" environment. This review(More)
A platform to study ultrasound as a source for wireless energy transfer and communication for implanted medical devices is described. A tank is used as a container for a pair of electroacoustic transducers, where a control unit is fixed to one wall of the tank and a transponder can be manually moved in three axes and rotate using a mechanical system. The(More)
The goal of this paper is to prove that a safe and efficient energy transfer is possible between an external transducer located on the patient's skin and a device deeply implanted in the abdomen. An ultrasound propagation model based on the Rayleigh-Sommerfeld diffraction integral is coupled with the data from the Visible Human Project to account for the(More)
The goal of this study is to optimize the transfer of acoustic energy deep in the body. In order to find suitable acoustic paths for the energy transfer to be efficient, we propose a model of ultrasound propagation that takes into account a realistic geometry of the tissue layers inside the human body. The data from the Visible Human Project is used to(More)
