I was to have a watchman device implanted on Dec 22.2020. The procedure was a failure in that out of 3 devices, none would seal off the opening. Very disappointed in this. Surgeon said the rep from the makers told him they are coming out with newer devices that will be more flexable sometime in Feb, Mar, Apr timeframe. I am on the list to get one of those. The procedure itself was full of surprises for me. Please make sure you know what is going to happen in your procedure.
