Left atrial appendage closure device with occlusive member retention feature

A left atrial appendage closure (LAAC) device, comprising:

• an expandable frame adapted to shift between a collapsed configuration and an expanded configuration, the expandable frame comprising a plurality of expandable frame struts;
• an occlusive member disposed over the expandable frame;
• and
• a plurality of anchor members, each of the plurality of anchor members coupled with a corresponding one of the plurality of expandable frame struts, each of the plurality of anchor members comprising:
• an anchor member base extending laterally from the corresponding expandable frame strut;
• an anchor member strut extending axially from the anchor member base and substantially parallel with the corresponding expandable frame strut;
• a tissue engaging region extending from the anchor member strut;
• and
• one or more pairs of opposing barbs, each pair of opposing barbs including a first barb extending towards the corresponding expandable frame strut from the anchor member strut and a second barb extending towards the anchor member strut from the corresponding expandable frame strut.
