1. A medical device for occluding a left atrial appendage of a heart, comprising:
an occluder portion coupled to a hub defining an axis, the occluder portion having occluder frame segments extending radially outward from the hub to a distal end portion of the occluder portion, multiple ones of the occluder frame segments at the distal end portion define a first eyelet;
an anchor portion having anchor frame segments, the anchor frame segments extending between first and second ends, the second end of the anchor frame segments coupled to an anchor hub and the first end of the anchor frame segments define a second eyelet adjacent thereto; and
multiple hinge components, each of the hinge components including a base with arms extending from the base such that the arms of each one of the hinge components extend through and capture the first eyelet and the second eyelet of one of the occluder frame segments and one of the anchor frame segments, respectively, to facilitate pivotably coupling the anchor portion to 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 the first eyelet to prevent pivotable movement of the occluder frame segments relative to a corresponding one of the hinge components.
