Medical device for modification of left atrial appendage and related systems and methods
First Claim
1. A method of modifying a left atrial appendage of a heart, the method comprising:
- advancing a medical device with a catheter of a delivery system through a vasculature and into the left atrial appendage of the heart, the medical device including a framework extending between a primary hub and a secondary hub, the primary hub and the secondary hub having a common axis;
deploying the framework adjacent the left atrial appendage from a constricted position to a deployed position so that the secondary hub is moveable along the axis relative to the primary hub such that the secondary hub remains proximal a distal end of the framework;
securing the framework to tissue in the left atrial appendage with engaging members positioned on the framework proximal the distal end of the framework, the framework at a distal side thereof extending radially and distally toward the distal end, and turns to extend radially and proximally inward toward the secondary hub; and
releasing the catheter from the medical device and withdrawing the delivery system from the heart to permanently leave the medical device in the left atrial appendage.

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 device includes a framework extending between a primary hub and a secondary hub. The secondary hub is moveable relative to the primary hub upon deploying the framework from a constricted position to a deployed position such that the secondary hub remains proximal a distal end of the framework. The framework, in the deployed position, includes engaging members proximal the distal end of the framework, and the framework includes multiple frame segments each extending with an arcuate configuration at a distal side of the framework such that the frame segments, at the distal side thereof, each extend radially and distally toward the distal end, then turn and extend radially and proximally inward toward the secondary hub.
