Medical device for modification of left atrial appendage and related systems and methods
First Claim
1. A medical device for implantation in a left atrial appendage of a heart, the medical device comprising:
- an occluder portion having a hub and defining an axis, the occluder portion extending between a proximal end coupled to the hub and a distal end defining an occluder eyelet adjacent thereto; and
an anchor portion extending between a first end and a second end, the first end coupled to an anchor hub and the second end defining an anchor eyelet adjacent thereto and hingeably coupled to the occluder eyelet;
wherein the anchor hub is moveable along the axis relative to the hub to move the anchor portion between a retracted position and a deployed position upon the occluder portion being in an expanded 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 medical device includes an occluder portion and an anchor portion. The occluder portion includes a hub that defines an axis, the occluder portion extending between a proximal end coupled to the hub and a distal end defining an occluder eyelet adjacent thereto. The anchor portion extends between a first end and a second end, the first end coupled to an anchor hub and the second end defining an anchor eyelet adjacent thereto and hingeably coupled to the occluder eyelet. With this arrangement, the anchor hub is moveable along the axis to move the anchor portion between a retracted position and a deployed position upon the occluder portion being in an expanded position.

7. A medical device for implantation in a left atrial appendage of a heart, the medical device comprising:
-
a framework having a proximal end and a distal end and defining an axis, the framework extending between a primary hub and a secondary hub, the primary hub and the secondary hub aligned along the axis of the framework, the primary hub extending distally relative to the proximal end of the framework to a primary hub distal end, the framework extending radially outward and distally relative to the primary hub and extending radially inward and proximally toward the secondary hub such that the secondary hub is positioned proximal the distal end of the framework; and a polymeric member positioned along a proximal side of the framework so as to extend to a polymeric member distal end, wherein the primary hub distal end is positioned proximal the polymeric member distal end. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for occluding a left atrial appendage, the method comprising:
-
positioning a framework within the left atrial appendage, the framework having a proximal end and a distal end and defining an axis, the framework extending between a primary hub and a secondary hub, the primary hub and the secondary hub aligned along the axis of the framework, the framework extending radially outward and distally relative to the primary hub and extending radially inward and proximally toward the secondary hub such that the secondary hub is positioned proximal the distal end of the framework; and permanently implanting the framework in the left atrial appendage. - View Dependent Claims (19, 20)
