METHODS TO PREVENT STRESS REMODELING OF ATRIAL TISSUE

摘要

Methods and devices are disclosed herein for therapeutically treating atrial tissue to lessen the effects of mechanical stress on atrial tissue, where reducing mechanical stress in the portion of atrial tissue reduces formation of at least one arrhythmia substrate. In one example, the devices and methods are suitable for minimally invasive surgery. More particularly, methods and devices described herein permit creating an ablation pattern on an organ while reducing excessive trauma to a patient.

1. A method for reducing and preventing atrial fibrillation in an atrial tissue of a heart, the method comprising:
identifying an affected region of the atrial tissue, where the affected region of the atrial tissue is subject to a mechanical stress produced as a result of an existing medical condition; and producing a treated section of the atrial tissue by applying energy thereto, such that the treated section of the atrial tissue provides increased mechanical support to the affected region of the atrial tissue, where the increased mechanical support reduces the mechanical stress in the affected region of tissue to reduce the occurrence of atrial fibrillation within the atrial tissue.
