Abstract

Claims (24)

1. A method of anchoring an occluder device within a left atrial appendage (LAA) of a heart, comprising:

providing an anchoring system for implanting the occluder device within the LAA, wherein the anchoring system comprises:

a) an outer sheath;

b) a delivery catheter;

c) an occluder device for a LAA;

d) an anchor;

e) a contracted first position of the anchor; and

f) a deployed second position of the anchor;

inserting the outer sheath into the LAA through a left atrium proper of the heart;

advancing the delivery catheter through the outer sheath into the LAA;

perforating an inner endocardium layer, a middle myocardium layer, and an outer epicardium layer of an LAA wall of the heart using the delivery catheter;

creating a small hole through the LAA wall into a pericardial space using the delivery catheter;

advancing the occluder device and anchor into the LAA using the delivery catheter, wherein the anchor is in the contracted first position;

advancing the anchor in the contracted first position through the inner endocardium layer, the middle myocardium layer, and the outer epicardium layer of the LAA wall using the delivery catheter;

further advancing the anchor in the contracted first position into the pericardial space through the small hole in the LAA wall using the delivery catheter;

expanding the anchor from the contracted first position to the deployed second position; and

releasing the occluder device from the outer sheath to occlude the LAA;

wherein the occluder device is moored to the LAA wall via the anchor.

2. The method of claim 1 , wherein the anchor is integral with the occluder device.

3. The method of claim 1 , further comprising:

retrieving the occluder device inside the outer sheath;

removing the anchor from the LAA wall, wherein the anchor retracts from the deployed second position to the contracted first position;

advancing the anchor through the inner endocardium layer, the middle myocardium layer, and the outer epicardium layer at a different location of the LAA wall; and

releasing the occluder device from the outer sheath to occlude the LAA.
