MECA11013-T1

Transoesophageal device using high intensity focused ultrasounds for cardiac thermal ablation

The present invention relates to a probe comprising: a piezoelectric therapy transducer having an acoustic axis BB’, and an imaging transducer having an imaging plane, said therapy transducer and imaging transducer being mounted in a head itself connected to a guide means wherein: the therapy transducer has a spherical concave front face for emitting ultrasonic waves focused on a focal point, a rear surface , a length d1, a width t and is a 1D annular phased array transducer and; the imaging transducer is a multiplane transducer having a rotation axis corresponding to the acoustic axis of the therapy transducer whereby the focal point of the therapy transducer is comprised in the imaging plane of the imaging transducer, said imaging transducer being fixed to the therapy transducer.
