Abstract

An ablation catheter includes a tubular catheter body having a lumen, a tip portion, a liquid inlet, at least one liquid outlet, a liquid flow path defined between the liquid inlet and the liquid outlet, and an ablation element mounted on the tip portion of the catheter body. A rotationally-scanning ultrasound assembly is disposed within the lumen of the catheter body adjacent the tip portion. The ultrasound assembly includes an ultrasound transducer having an active face, an acoustic mirror acoustically coupled to the active face of the ultrasound transducer, and an impeller positioned in the liquid flow path and operably coupled to at least one of the ultrasound transducer and the acoustic mirror to impart rotational motion thereto when a liquid flows through the impeller.
