Abstract
A therapy apparatus for treating tissue by emission of focused ultrasound waves, including: a creation surface of a pressure field of focused ultrasound waves divided into at least N sectors having segments of asymmetrical concave curve with centres of curvature; centres of curvature asymmetrical to the extent where the centres of curvature are situated at different distances from the plane of symmetry or from at least one of the axis of symmetry and at different depths taken according to the axis of symmetry; the individual axes intersecting between the focal zones and the creation surface or beyond the focal zones such that the beams originating from the sectors intersect to create a focal coverage zone which is off-axis relative to the plane of symmetry or to the axis of symmetry; the sectors of this creation surface creating energy deposit zones with profiles corresponding to the focal coverage zones.
