Occlusive medical device with fabric retention barb

An occlusive implant system, comprising:

• a catheter having a lumen extending from a proximal opening to a distal opening;
• a core wire slidably disposed within the lumen;
• and
• an occlusive implant having an expandable framework configured to shift between a collapsed configuration and an expanded configuration that is configured to conform to and to be in a sealing engagement with a lateral wall of a left atrial appendage, and an occlusive element disposed on the expandable framework;
• wherein the expandable framework includes a plurality of anchor members extending radially outward from the expandable framework, and through the occlusive element, the plurality of anchor members each having a distal tip and a proximal body,
• wherein at least some anchor members of the plurality of anchor members are configured to secure the occlusive element to the expandable framework and each of the at least some of the plurality of anchor members have a barb that projects circumferentially therefrom at a point proximal of the distal tip and distal of the occlusive element;
• wherein the occlusive implant is releasably connected to a distal portion of the core wire.

An occlusive implant, comprising:

• an expandable framework configured to shift between a collapsed configuration and an expanded configuration that is configured to conform to and to be in a sealing engagement with a lateral wall of a left atrial appendage;
• and
• an occlusive element disposed over an outer surface of the expandable framework;
• wherein the expandable framework includes a plurality of anchor members extending radially outward from the expandable framework and through the occlusive element;
• wherein at least some of the plurality of anchor members each have two barbs projecting circumferentially therefrom at points distal of the occlusive element and proximal of a distal tip of the at least some of the plurality of anchor members and are configured to secure the occlusive element to the expandable framework.
