1. A method of occluding a left atrial appendage (“LAA”) of a patient with a medical device, the method comprising:
accessing the patient's right atrium via a femoral vein;
advancing a delivery catheter distally through an opening in a septum of a heart of the patient until a distal end of the delivery catheter is positioned proximate to the LAA or within the LAA;
when the distal end of the delivery catheter is positioned proximate to the LAA or within the LAA, advancing a distal lobe of the medical device out of the delivery catheter to allow the distal lobe to transition from a collapsed condition to an expanded condition;
positioning the distal lobe of the medical device within the LAA;
deploying a proximal flange of the medical device from the delivery catheter; and
positioning the proximal flange into contact with tissue of a left atrium of the patient that forms an ostium leading into the LAA, such that the distal lobe is positioned within the LAA, the proximal flange is positioned outside the LAA, and a waist of the medical device extends through the ostium and connects the distal lobe to the proximal flange, the waist having a diameter that is smaller than a diameter of the distal lobe and smaller than a diameter of the proximal flange,
wherein, in the expanded condition of the distal lobe, the distal lobe has a generally cylindrical shape that includes a proximal wall end extending radially outwardly from the waist, a side wall extending distally from the proximal wall, the side wall tapering in a distal direction to a distal wall that extends radially inwardly to a center point, the distal lobe being formed of structural members that converge at the center point of the distal wall.
