1. Apparatus for inactivating renal nerve conduction in a mammalian subject comprising:

  • an ultrasound transducer adapted for insertion into a renal artery of the mammalian subject and for transmitting unfocused ultrasound energy; and

    an actuator electrically connected to the transducer, the actuator being adapted to control the ultrasound transducer to transmit unfocused ultrasound energy into an impact volume of at least 0.5 cm3, encompassing the renal artery so that the unfocused ultrasound energy is applied at a therapeutic level sufficient to inactivate conduction of renal nerves throughout the impact volume.
