Abstract
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 system for use in occluding an opening in the tissue of a body includes a handle, a catheter coupled with the handle and a medical device disposed within a lumen of the catheter. The medical device includes an anchor system having a plurality of anchor segments coupled with an anchor hub. The medical device further includes an occluder system having a plurality of occluder segments coupled with an occluder hub. A first actuator is configured to displace the occluder hub independent of, and relative to, the anchor hub to deploy the occluder system from a refracted state to an expanded state while the anchor system remains in a retracted state.
