1. A method of occluding a left atrial appendage of a heart, the method comprising:
advancing a medical device with a catheter through a vasculature and to the left atrial appendage, the medical device having a framework extending between a primary hub and a secondary hub, the primary hub and the secondary hub having a common axis, the framework extending with hinge components between an occluder portion and an anchor portion of the framework such that each of the hinge components includes a base and arms extending from the base;
deploying the framework adjacent the left atrial appendage from a constricted position to a deployed position such that the secondary hub is moveable along the axis relative to the primary hub and such that the anchor portion pivots about the hinge components with the arms of each of the hinge components positioned through corresponding ones of an anchor eyelet defined in the anchor portion and the arms of each of the hinge components positioned through corresponding ones of an occluder eyelet defined in the occluder portion, each of the hinge components including a key structure, the key structure sized and configured to correspond and engage with recesses defined in corresponding ones of the occluder eyelet to prevent pivotable movement of the occluder portion relative to a corresponding one of the hinge components; and
releasing the medical device from the catheter with the framework of the medical device secured to tissue adjacent the left atrial appendage.
