摘要
A method and device for the treatment of atrial fibrillation by inhibiting the flow of electricity from the pulmonary vein to the left atrium. The method includes inhibiting electrical flow by disabling the conductive fibers mechanically, using an incision (70), or via fibrosis, or chemically by applying toxic substances to the fibers. In one embodiment, a device (30) is useable to deliver a prosthetic structure (10) to the pulmonary vein that is useable to stretch the pulmonary vein, thereby inducing fibrosis, keeping the incision (70) open, or delivering a substance to the endothelium of the pulmonary vein. The structure (10) delivered by the device (30) is a self-expanding prosthetic structure. In another embodiment, a device (60) is useable to deliver and expand a prosthetic structure (10) that is expandable but not self-expanding.
