Abstract

A simple device is provided that addresses the concerns of safety, efficiency and efficacy in closing the atrial appendage by conventional or minimally invasive cardiac surgical techniques. The device preferable is formed of a generally elliptical body with a through opening and at least two opposing magnetic serrations for closing the opening. During application, the opening is held open to prevent the magnetic serrations from prematurely coapting. The device is passed about the left atrial appendage through the opening to position the body about a neck of the left atrial appendage. Once the device is in place, the opposing magnetic serrations are permitted to coapt, closing the opening and occluding the orifice of the neck in a generally linear line of closure.
