摘要: High-voltage pulses ablation systems and methods are used to ablate tissue and form lesions. A variety of different electrophysiology devices, such as catheters, surgical probes, and clamps, may be used to position one or more electrodes at a target location. Electrodes can be connected to power supply lines and, in some instances, the power to the electrodes can be controlled on an electrode-by-electrode basis. High-voltage pulse sequences provide a total amount of heating that is typically less than that which is observed with thermally-based radiofrequency energy ablation protocols.

摘要: A medical probe includes an elongate member having a proximal end and a distal end, an ablative element mounted to the distal end of the elongate member, and a cage assembly mounted to the distal end of the elongate member, the cage assembly at least partially covers the ablative element. A method of treating tissue in a body includes inserting an ablative element in the body, placing the ablative element adjacent the tissue, and maintaining a distance between the ablative element and the tissue using a protective catheter element that circumscribes at least a portion of the ablative element.
