  • Patent number: 10327732
    Abstract: The method of characterizing an ultrasound lesion (T) in organic tissues, the lesion being made by applying high intensity focused ultrasound delivered by a probe having its emission surface presenting a shape that is toroidal, consists in: after a period of at least two days from the end of ultrasound application, acquiring at least one characterization image (Ic) of the organic tissues; detecting the presence of a contrast border (16) in the characterization image (Ic); and from the contrast border (16), determining the extent of the ultrasound lesion.

  • Publication number: 20180177519
    Abstract: The invention relates to a method for generating ultrasonic waves focused on a focal zone (5) in order to carry out biological lesions, comprising the activation of a plurality of ultrasonic transducer elements (3). According to the invention: a target zone, in which homogenization of the supply of energy of the ultrasonic waves emitted by the ultrasonic transducer elements is desired, is chosen, the focusing effect and the acoustic attenuations of the ultrasonic waves on their path between the target zone and the ultrasonic transducer elements (3) are determined, the focusing effect and the acoustic attenuations of the ultrasonic waves are compensated, with ultrasonic transducer elements (3) at least some of which have non-identical emission surfaces such that in the target zone, the supply of energy of the ultrasonic waves emitted by the different ultrasonic transducer elements (3) is more or less identical.

  • Patent number: 9737324
    Abstract: A therapeutic probe having a transducer for focusing the ultrasonic waves into a first focal area, the emission surface of which has, within a profile plane, two concave curve segments which have a finite length and which are symmetrical relative to a plane of symmetry, or to an axis of symmetry. Within the profile plane, both concave curve segments extend along arcs of first and second non-coincident circles that intersect each other, and each curve segment has an acoustic axis intersecting the axis of symmetry, or the plane of symmetry, between the first focal area and the emission surface, the acoustic axes being spaced apart from each other such that the beams from the emission surface intersect each other so as to create a second focal area located in and situated between the first focal area and the emission surface.

  • Patent number: 6371903
    Abstract: An ultrasound therapy probe includes a therapy transducer movably mounted on a probe body, a partially deformable flexible casing disposed around the therapy transducer, and a guard ring that limits deformations of the flexible casing when the transducer moves with respect to the probe body. The therapy transducer can be moved between a therapy position and a retracted position, and the guard ring provides an end-of-travel stop against which the therapy transducer bears when in a therapy position. A first opening is provided for injecting liquid into the flexible casing, and a second opening is provided for withdrawing liquid from the flexible casing. The second opening is located on the guard ring so that bubbles are withdrawn from the flexible casing as soon as they form.

  • Patent number: 6071238
    Abstract: An ultrasound therapy probe is provided comprising a therapy transducer movably mounted on a probe body, an at least partially deformable flexible casing around the therapy transducer, and a guard ring limiting deformations of the flexible casing when the transducer moves with respect to the probe body. The therapy transducer can be moved between a therapy position and a retracted position, the guard ring constituting an end-of-travel stop against which the therapy transducer bears in a therapy position. This ensures that movements of the organ to be treated are kept to a minimum when the therapy transducer moves with respect to the probe body.

  • Patent number: 5720287
    Abstract: The therapy and imaging probe of the invention comprises a probe body (20') of an elongate shape defining a general axis (X--X), one imaging transducer (40') for transmitting imaging waves, and one therapy transducer (30') for transmitting therapy waves. The imaging transducer is mounted on first support means providing translational movement of the imaging transducer within the probe, parallel to the general axis (X--X) of the probe, between a withdrawn position and an extended position. The therapy transducer is mounted on second support means providing rotation of the therapy transducer within the probe, about an axis of rotation (X1--X1) parallel to the general axis (X--X) of the probe but offset with respect to the imaging transducer, to allow rotation of the therapy transducer between a withdrawn position and a treatment position.
