    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: Systems and methods support arrays of multiple electrodes in asymmetric pattern, either radially, or axially, or both. Radial asymmetry makes it possible provide localized density of electrodes. Axial asymmetry makes it possible to locate electrodes in a pattern that closely conforms to the irregular contours of an interior body cavity, like the heart. In a preferred embodiment, the systems and methods operate the multiple electrode arrays to form continuous lesion patterns.
