Abstract
An ultrasound catheter includes an elongated body, a first and second ablation element each configured to ablate soft tissue and an imaging core having an ultrasound transducer. In another example, an ultrasound catheter includes an elongated body, a RF ablator configured to ablate soft tissue at a frequency less than 1 MHz, and an ultrasound transducer configured to image at a frequency greater than or equal to 10 MHz. In another example, an ultrasound catheter apparatus includes an ultrasound catheter having an ablator and an ultrasound transducer, and a graphical user interface displayed using a computer processor. The graphical user interface displays a real-time image of a treatment area and the ultrasound catheter, and a chart displaying ablation as a function of time, the chart being updated in real-time.
