An acoustic wave energy delivery device including an acoustic wave energy transducer for generating an acoustic wave along an acoustic wave propagation axis, focusing apparatus for focusing the acoustic wave to a focal point, and acoustic wave reorientation apparatus adapted to modify a spatial orientation of the acoustic wave propagation axis with respect to the focal point, wherein a position of the focal point is constrained within a locus referred to as the focal point locus, and throughout modification of the spatial orientation of the acoustic wave propagation axis the acoustic wave remains focused within the focal point locus. The focal point locus may be constrained to a single focal point.
