SYSTEM AND METHOD FOR ULTRASONICALLY SENSING AND ABLATING TISSUE

摘要

Echo-anatomically mapping tissue includes advancing a catheter having an ultrasound transducer toward tissue. A console adjacent the proximal end of the catheter controls catheter movement, and the ultrasound transducer senses tissue. First and second regions of the tissue are ultrasonically sensed while moving the ultrasound transducer along first, and second sensing patterns, respectively. A first 3-dimensional surface map of the first region, and a second 3-dimensional surface map of the second region are generated. The 3-dimensional surface maps are combined to form a combined surface map. Anatomical features may be identified in the first or second sensed regions. The tissue may be ultrasonically ablated while moving the ultrasound transducer along a first ablation path. The first ablation path may form a lesion around the identified anatomical features, and may be selected from a catalog of ablation paths or it may be prescribed by a physician.

1. A method for echo-anatomically mapping tissue, said method comprising:
advancing a catheter toward a target treatment tissue, the catheter comprising a proximal end, a distal end, a transducer adjacent the distal end, and a console adjacent the proximal end, wherein the console is configured to control movement of the catheter, and wherein the transducer is configured to have a sensing mode to sense the target treatment tissue and an ablation mode to ablate the target treatment tissue; sensing a first region of the target treatment tissue with the transducer while in the sensing mode while moving the transducer with a first sensing pattern; generating a first surface map of the first region; sensing a second region of the target treatment tissue with the transducer while in the sensing mode while moving the transducer with a second sensing pattern; combining the first surface map with the second surface map to form a combined surface map; generating an ablation path based on the combined surface map; switching the transducer from the sensing mode to the ablating mode; and ablating the target treatment tissue with the transducer.
