DEVICE WITH BIOLOGICAL TISSUE SCAFFOLD FOR PERCUTANEOUS CLOSURE OF AN INTRACARDIAC DEFECT AND METHODS THEREOF

摘要

The invention provides an intracardiac occluder (10), which has biological tissue scaffolds as occlusion shells, for the percutaneous transluminal treatment of an intracardiac defect. The intracardiac occluder includes a proximal support structure (24) supporting the proximal occlusion shell (18) and a distal support structure (34) supporting the distal occlusion shell (20). In one embodiment, biological tissue derived from the tunica submucosa layer of the porcine small intestine forms the occlusion shells.
