1. An occluder for occluding a left atrial appendage (“LAA”), the occluder comprising:
a self-expandable proximal disk sized and shaped to overlie an ostium of the LAA in an implanted condition of the occluder, the proximal disk formed of a plurality of metallic strands interwoven into a braided structure;
a proximal connector on the proximal end of the proximal disk, the proximal connector configured for reversible coupling to a delivery system;
a self-expandable body portion positioned distal to the proximal disk and sized and shaped to be received within the LAA and to engage a wall of the LAA in the implanted condition of the occluder; and
a transition section that couples the proximal disk to the body portion;
wherein in an expanded condition of the occluder, the proximal disk, the body portion, and the transition section each have a diameter, the diameter of the proximal disk being larger than the diameter of the body portion, and the diameter of the body portion being larger than the diameter of the transition section,
wherein in the expanded condition of the occluder and in the absence of applied forces, the body portion has a total length of between 3 mm and 25 mm, the total length including a section having a generally cylindrical shape extending a distance, a plurality of retention hooks extending radially outwardly from the section of the body portion having the generally cylindrical shape, and
wherein in the expanded condition of the occluder, at least part of the transition section is positioned radially inwardly of the body portion such that the body portion at least partially surrounds the transition section.
