1. An ultrasound ablation catheter, comprising:

  • a distal assembly comprising an ultrasound ablation transducer, an echolucent shell, and an ablation direction fiducial marker, the echolucent shell at least partially defining a distal chamber, the ultrasound ablation transducer disposed within the distal chamber, the distal assembly adapted to house therein an ultrasound imaging transducer,the ablation direction fiducial marker positioned relative to the ultrasound ablation transducer and adapted to, when an ultrasound imaging transducer is positioned and activated within the distal assembly, create an aiming artifact on an image created by the ultrasound imaging transducer, the aiming artifact adapted to be used to indicate a direction of ablation; and

    an elongate shaft extending proximally from the distal assembly.
