Title:
DEVICE WITH BIOLOGICAL TISSUE SCAFFOLD FOR INTRACARDIAC DEFECT CLOSURE
Document Type and Number:
WIPO Patent Application WO2003101312
Kind Code:
B1
Abstract:
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.
