1. A device for ablating tissue, comprising:

  • a body having a longitudinal axis and a contact surface configured to be positioned adjacent tissue to be ablated;

    a first transducer coupled to the body;

    a second transducer coupled to the body and spaced apart from the first transducer by a space;

    a first flexible membrane which extends over the first transducer, the first flexible membrane conforming to the surface of the tissue and being filled with a substance which transmits the ultrasound energy from the first transducer to the tissue when the first flexible membrane is in contact with the tissue; and

    a second flexible membrane which extends over the second transducer, the second flexible membrane conforming to the surface of the tissue and being filled with a substance which transmits the ultrasound energy from the second transducer to the tissue when the second flexible membrane is in contact with the tissue;

    wherein both of the first and second transducers are adapted to direct focused ultrasound energy to tissue lying beneath the space between the first and second transducers.
