    摘要: An ablation catheter having self assembling large surface area distal component provided with one or more energy emitting surfaces for thermally destroying tissue. The distal component is oriented to present a compact, low profile for introduction into the heart, and after introduction is reconfigured to present a large surface area distal ablation tip assembly. The distal tip component is subsequently returned to the low profile configuration for removal from the heart. Once introduced, the energy emitting surfaces are thus carried by a distal component having significantly enlarged surface area. The enlargable distal component is produced using a plurality of pivoting sections capable of alignment into a compact profile for introduction into and removal from a living body. When reconfigured by pivoting of the sections into contact with each other, the distal component has an significantly enlarged dimension.

    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.
