MEDICAL DEVICE FOR MODIFICATION OF LEFT ATRIAL APPENDAGE AND RELATED SYSTEMS AND METHODS
First Claim
1. A medical device for modifying a left atrial appendage (“
- LAA”
) of a heart, the medical device comprising;
an occluder portion including a proximal end and a distal end; and
an anchor portion operably coupled to the occluder portion, the anchor portion including multiple anchor segments each having a first end and a second end, wherein the first and second ends are proximal the distal end of the occluder portion.

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.
