SYSTEM AND METHODS FOR ABLATING TISSUE

摘要

Tissue ablation systems and methods for creating ablation zones in tissue comprises locating a target tissue and positioning an interventional catheter adjacent the target tissue. The interventional catheter has an energy source. Collateral tissue adjacent the target tissue is located. The target tissue is ablated with energy from the energy source so as to form a continuous lesion or region of ablation in the target tissue. The ablating is conducted so as to minimize ablating or otherwise damaging the collateral tissue and to increase the likelihood of procedure success.

1. A method for ablating tissue, said method comprising:
providing a catheter having an ultrasound transducer adjacent a distal end thereof and a sensor adjacent the ultrasound transducer; positioning the ultrasound transducer and the sensor adjacent target tissue; sensing collateral tissue adjacent the target tissue; determining a lesion path based on the target tissue and the collateral tissue; and ablating the target tissue along the lesion path with a beam of ultrasound from the ultrasound transducer thereby forming a continuous lesion in the target tissue.
