    摘要： A method of ablating tissue in the heart to treat atrial fibrillation introduces into a selected atrium an energy emitting element. The method exposes the element to a region of the atrial wall and applies ablating energy to the element to thermally destroy tissue. The method forms a convoluted lesion pattern comprising elongated straight lesions and elongated curvilinear lesions. The lesion pattern directs electrical impulses within the atrial myocardium along a path that activates the atrial myocardium while interrupting reentry circuits that, if not interrupted, would cause fibrillation. The method emulates the surgical maze procedure, but lends itself to catheter-based procedures that do not require open heart surgical techniques. A composite structure for performing the method is formed using a template that displays in planar view a desired lesion pattern for the tissue. An array of spaced apart element is laid on the template. Guided by the template, energy emitting and non-energy emitting zones are formed on the elements. By overlaying the elements, the composite structure is formed, which can be introduced into the body to ablate tissue using catheter-based, vascular access techniques.

    摘要翻译： 心脏中消融组织以治疗心房颤动的方法将所选择的心房引入能量发射元件。 该方法将该元件暴露于心房壁的一个区域，并向该元件施加消融能量以热破坏组织。 该方法形成包括细长的直线损伤和细长的曲线损伤的褶皱病变图案。 病变图案沿着激活心房心肌的路径引导心房心肌内的电脉冲，同时中断再入电路，如果不中断，将引起原纤维化。 该方法模拟外科迷宫手术，但适用于不需要开放心脏手术技术的基于导管的手术。 用于执行该方法的复合结构使用在平面图中显示用于组织的期望损伤图案的模板来形成。 间隔开的元件阵列放置在模板上。 在模板的指导下，在元件上形成能量发射和非能量发射区。 通过覆盖元件，形成复合结构，其可以引入体内以使用基于导管的血管通路技术来烧蚀组织。
