A medical device, system and method for modifying a left atrial appendage. The device has a central shaft with a hollow interior. Different portions of data packets are sent by the sending endpoint over different ones of the multiple data communication channels. The diameter of the actuation spur wheel is more than 0. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.
