Abstract
Apparatus and methods are described including a catheter ultrasound transducer that includes one or more piezoelectric elements configured to ablate tissue of an ostium of a blood vessel by applying ultrasound energy to tissue of the ostium. An expandable positioner is configured to envelope at least a portion of the catheter ultrasound transducer and to position the catheter ultrasound transducer in the ostium of the blood vessel by contacting a wall of the blood vessel. A system processor in communication with the one or more piezoelectric elements is configured to regulate a parameter of the ultrasound energy emitted from the one or more piezoelectric elements based on impedance measurement between one or more electrodes located on the expandable positioner and one or more electrodes located on the catheter ultrasound transducer. Other applications are also described.
