1. A method for ablation of arrythmogenic cardiac tissue comprising:
- selecting a catheter comprising;
an elongated flexible body having a proximal end and a distal end,an ultrasound assembly having a transducer located at the distal end of the body, anda tissue ablation means;
introducing the distal end of the catheter into a cardiac chamber comprising the arrythmogenic cardiac tissue to be ablated;
using the ultrasound assembly to position the tissue ablation means within an effective range of the arrythmogenic cardiac tissue to be ablated; and
activating the tissue ablation means.

Abstract
Method and apparatus for ablation of cardiac tissue includes a catheter (2, 60) having an elongated flexible body (6, 64), a tissue characterization assembly including a transducer (34) at the distal end (16) of the body and a tissue ablation assembly having a tissue ablation tip (32) at the distal end of the body. The tissue ablation tip is positioned adjacent the tissue to be ablated using the visualization assembly and then activated.
