Abstract
Methods for applying heat to a region proximate a blood vessel are disclosed. In one embodiment, a method can include generating an imaging ultrasound beam adapted to image a blood vessel target and receiving a reflection of the imaging ultrasound beam. The method can also include producing an output signal in response to the reflection of the imaging ultrasonic beam and processing the output signal to identify a location of a treatment zone proximate an outer wall of the blood vessel. Therapeutic energy can be applied to the treatment zone. In some embodiments, the therapeutic ultrasound energy beam can be moved to over-scan the treatment zone. Other methods are also disclosed.
