Implant for occluding a left atrial appendage

An implant for occluding a left atrial appendage, comprising:

• a plurality of foam layers attached together;
• wherein each foam layer of the plurality of foam layers comprises a plurality of wedges monolithically formed with a base portion;
• and
• a cap layer of foam attached at an axial end of the plurality of foam layers attached together;
• wherein the cap layer of foam is disk-shaped and is devoid of wedges.

A method of making an implant for occluding a left atrial appendage, comprising:

• cutting a first disk-shaped piece of foam partially through a thickness of the first disk-shaped piece of foam to define a first plurality of wedges monolithically formed with a first base portion;
• securing the first base portion in a contracted configuration to flare the first plurality of wedges apart from each other;
• cutting a second disk-shaped piece of foam partially through a thickness of the second disk-shaped piece of foam to define a second plurality of wedges monolithically formed with a second base portion;
• securing the second base portion in a contracted configuration to flare the second plurality of wedges apart from each other;
• and
• attaching the first base portion to the second base portion such that the first plurality of wedges is interdigitated with the second plurality of wedges.
