Focused ultrasound cardiac stimulation system, portable device and cardiac stimulation, and related methods

摘要

The invention relates to a device for measuring the electrical activity of the heart in order to acquire an electrocardiogram (ECG) and means for generating a beam of focused ultrasound signals (Fus) focused on the target zone (Zc) Wherein the signal is calibrated for generating an electrical stimulus or the like in a zone of the heart such that the beam generation is synchronized with a first selected time of an electrocardiogram (ECG) Means for generating a focused beam (Fus) to control said beam of focused ultrasound signals (Fus) in the target zone (Zc), corresponding to pulses whose duration is shorter than 80 ms Means for locating a target zone (Zc) coupled to the means for positioning the means of the focusing signal (Fus), characterized in that it comprises means , Single monitoring means capable of tracking temperature and tissue deformation within the target zone (Zc) in real time, said monitoring means for making measurements synchronously with the tuning of the electrocardiogram, ultrasonic cardiac stimulation System.
