Expanding foam delivery system for occluding left atrial appendage

A left atrial appendage closure (LAAC) device adapted for occluding the left atrial appendage (LAA), the LAAC device comprising:

• an expandable foam cone-shaped implant adapted for trans-septal delivery to the LAA;
• a cone-shaped covering disposed over the expandable foam cone-shaped implant, the cone-shaped covering adapted to protect the expandable foam cone-shaped implant during trans-septal delivery to the LAA, the cone-shaped covering including a distal region having a plurality of perforations adapted to split apart to facilitate removal of the cone-shaped covering;
• an insert lumen extending through the cone-shaped implant when in its delivery configuration;
• and
• a tubular support rod extending through the implant lumen, the tubular support rod operably coupled with at least a portion of the cone-shaped covering, the tubular support rod itself defining a tubular support rod lumen extending therethrough.

A left atrial appendage closure (LAAC) device adapted for occluding the left atrial appendage (LAA), the LAAC device comprising:

• a shape memory foam implant adapted for trans-septal delivery to the LAA;
• a cone-shaped covering disposed over the shape memory foam insert, the cone-shaped covering adapted to protect the shape memory foam implant during trans-septal delivery to the LAA, the cone-shaped covering including a distal region having a plurality of perforations adapted to split apart to facilitate removal of the cone-shaped covering;
• an implant lumen extending through the shape memory foam implant when in its delivery configuration;
• and
• a tubular support rod extending through the implant lumen, the tubular support rod operably coupled with at least a portion of the cone-shaped covering, the tubular support rod itself defining a tubular support rod lumen extending therethrough;
• wherein the shape memory foam implant is adapted to expand in diameter upon implantation within the LAA.
