Abstract
An absorbable and expandable closure member used to occlude or exclude a body lumen or cavity, such as a blood vessel, fallopian tube, duct, aneurysmal sac, etc., comprising a closure member comprising one of more sheets of a biomaterial that are rolled, stacked, or folded to form a multilayer construct of a generally cylindrical configuration for deployment through a delivery system, either as a singularly or part of a multiplicity of closure members. The biomaterial is derived from a source material, such as small intestinal submucosa or another remodelable material (e.g., an extracellular matrix) having properties for stimulating ingrowth of adjacent tissue into the biomaterial deployed within the bodily lumen. The closure member is deployed to the bodily lumen from a delivery sheath, cartridge, and/or over a inner guiding member, such as a wire guide or catheter.
