FOCUSSED ULTRASOUND CARDIAC STIMULATION SYSTEM, PORTABLE DEVICE AND CARDIAC STIMULATION, AND ASSOCIATED METHODS

摘要

The invention relates to an ultrasound cardiac stimulation system which comprises: a means for measuring the electrical activity of the heart in order to acquire an electrocardiogram (ECG); a means for generating a beam of focussed ultrasound signals (Fus) focussed on a targeted zone (Zc), said signals being calibrated such as to generate electrical stimulation in a zone of the heart, said beam generation being synchronised with a first selected time of the electrocardiogram (ECG), the generation of the beam corresponding to a pulse with a duration of less than 80 ms; a means for locating the targeted zone (Zc) coupled with a means for positioning the means for generating the focussed beam (Fus) so as to control said beam of focussed ultrasound signals (Fus) in the targeted zone (Zc), said location means being synchronised with the means for generating the beam of focussed signals (Fus); a single monitoring means capable of following in real time a temperature and a tissue deformation in the targeted zone (Zc), said monitoring means taking measurements in synchronisation with the rhythm of the electrocardiogram.
