Medical device for modification of left atrial appendage and related systems and methods
First Claim
1. A method of modifying a left atrial appendage (“
- LAA”
) of a heart, the method comprising;
advancing a medical device with a catheter of a delivery system through a vasculature and into the LAA of the heart, the medical device including an occluder portion coupled to a hub and an anchor portion operably coupled to the occluder portion;
deploying only the occluder portion from the delivery system within the LAA such that the anchor portion is in a proximal position relative to a distal end of the deployed occluder portion;
moving the deployed occluder portion within the LAA;
confirming a preferred position of the deployed occluder portion within the LAA;
moving the anchor portion between a retracted position and a deployed position subsequent to confirming the preferred position of the deployed occluder portion such that, upon the anchor portion being moved to the deployed position, at least a portion of the anchor portion is moved distal of the distal end of the deployed occluder portion;
engaging tissue within the LAA with the anchor portion to anchor the occluder portion in the preferred position within the LAA such that the anchor portion engages tissue at a distal position relative to the distal end of the deployed occluder portion; and
releasing the catheter from the medical device and withdrawing the delivery system from the heart to permanently leave the anchor portion and the occluder portion of the medical device in the LAA.

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.
