1. A medical device system for modifying a left atrial appendage of a heart, the medical device system comprising:
- a sheath having a length and defining a sheath lumen extending through the length of the sheath; and
a delivery system including a delivery catheter extending between a proximal end and a distal end, a handle coupled to the proximal end of the delivery catheter, and a medical device operatively coupled to the handle and disposed adjacent the distal end of the delivery catheter, the medical device comprising;
a hub including a bore defining an axis;
an occluder portion coupled to the hub, the occluder portion configured to be moved to an occluder non-deployed position with the occluder portion within a distal portion of the sheath, and the occluder portion configured to be moved to an occluder deployed position upon the sheath being moved proximally relative to the occluder portion; and
an anchor portion extending between a first end and a second end, the anchor portion having tines configured to engage tissue within the left atrial appendage, the first end being operatively coupled to the handle, the second end being pivotably coupled to a distal end portion of the occluder portion, wherein, upon the occluder portion maintaining the occluder deployed position, the anchor portion is pivotable relative to the occluder portion between an anchor non-deployed position and an anchor deployed position;
wherein the hub includes a hub distal end that remains proximal a distal end of the occluder portion; and
wherein the anchor portion is pivotably coupled to the distal end portion of the occluder portion with an eyelet to facilitate the anchor portion to pivot between the anchor deployed position and the anchor non-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 medical device includes an occluder portion and an anchor portion, the anchor portion hingably coupled to the occluder portion. With this arrangement, the anchor portion actuates and pivots relative to the occluder portion between an anchor deployed position and an anchor non-deployed position while the occluder portion is in an occluder deployed position.

15. A medical device for modifying a left atrial appendage of a heart, the medical device comprising:
-
a hub defining an axis; an occluder portion coupled to the hub, the occluder portion independently moveable relative to the anchor portion between an occluder non-deployed position and an occluder deployed position; and an anchor portion hingably coupled to a distal end portion of the occluder portion, the anchor portion having tines configured to engage tissue within the left atrial appendage, the anchor portion pivotable relative to the occluder portion between an anchor non-deployed position and an anchor deployed position upon the occluder portion being in the occluder deployed position; wherein the hub includes a hub distal end that remains proximal a distal end of the occluder portion; and wherein the anchor portion is hingably coupled to the distal end portion of the occluder portion with an eyelet to facilitate the anchor portion to pivot between the anchor deployed position and the anchor non-deployed position. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
