More Information
Summary:Devices, systems, and methods are provided for treating a condition of a heart, in particular the occurrence of arrhythmia. The devices, systems, and methods deliver therapeutic energy to portions of the heart, such as to the entrance of the pulmonary veins when treating atrial fibrillation, to provide tissue modification. Generally, a tissue modification system includes a dedicated catheter, a high voltage waveform generator, and at least one different energy delivery algorithm. Other embodiments include conventional ablation catheters and system components to support use with high voltage waveform generators. Example catheter designs include a variety of delivery types, including local delivery, "single delivery" delivery, and various possible combinations. In some embodiments, energy is delivered in a monopolar manner. However, it may be understood that a variety of other embodiments are also provided. 提供了用于处理心脏的状况，特别是心率失常的发生的设备、系统和方法。该设备、系统和方法向心脏的部分，例如在处理房颤时向肺静脉入口递送治疗能量以提供组织改造。一般而言，组织改造系统包括专用导管、高电压波形发生器和至
