摘要：
Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a delivery system for use in occluding an opening in the tissue of a body includes an actuation assembly operatively coupled to a medical device including an anchor portion and an occluder portion. The actuation assembly is configured to move the anchor portion between a deployed state and retracted state while the occluder portion maintains a deployed state. With this arrangement, the deployed occluder portion can be visualized via imaging at a preferred position prior to deploying the anchor portion of the medical device.
