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 coupled to a hub; and
an anchor portion operably coupled to the occluder portion, the anchor portion configured to roll-inward to a retracted position and roll-outward to a deployed position.

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.

14. A medical device for modifying a left atrial appendage (LAA) of a heart, the medical device comprising:
-
an occluder portion coupled to a hub; and an anchor portion operably coupled to the occluder portion, the anchor portion configured to be moved to a retracted position by at least partially inverting the anchor portion relative to the occluder portion and configured to be moved to a deployed position by at least partially everting the anchor portion relative to the occluder portion. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A medical device for modifying a left atrial appendage of a heart, comprising:
-
an occluder portion coupled to a hub, the occluder portion being moveable between a nondeployed position and a deployed position; an anchor portion operably coupled to the occluder portion, the anchor portion including multiple anchor segments having engaging members oriented and configured to engage tissue of the LAA when the anchor portion is in a tissue-engaging position; and a plurality of extensions, each extension being coupled to an associated anchor segment and extending inward and proximally from a location adjacent the engaging members, each extension configured to be pulled proximally to move the engaging members from the tissue-engaging position to a tissue-nonengaging position while the occluder portion is in the deployed position. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
