1. An apparatus for the treatment of tissue with ultrasound energy by direct contact, comprising:

  • a) an ultrasound horn containing;

    i. a proximal end including a proximal surface;

    ii. a distal end opposite the proximal end including a distal surface;

    iii. a radial surface extending between the distal end and the proximal end; and

    iv. a longitudinal axis extending through the horn from the proximal end to the distal end;

    b) an ultrasound tip connected to the distal end of the horn capable of delivering ultrasound energy to the tissue comprising;

    i. a back side;

    ii. a radial side opposite the backside forming a paraboloid cavity including an opening wherein a plane including the opening is not oriented orthogonal to the longitudinal axis of the horn; and

    iii. a jagged edge at least partially encircling the opening of the cavity;

    c) at least one channel running through at least a portion of the horn and into the cavity, containing an opening within a surface of the horn, and an opening within the radial side of the tip; and

    d) a non-atomized coupling medium delivered to the cavity through at least one of the channels opening within the radial side of the tip.
