Abstract

Implant devices for filtering blood flowing through atrial appendage ostiums have elastic cover and anchoring substructures. The substructures may include reversibly folding tines or compressible wire braid structures. The devices are folded to fit in catheter tubes for delivery to the atrial appendages. The devices elastically expand to their natural sizes when they are expelled from the catheter tubes. Filter elements in the covers block emboli from escaping through the ostiums The devices with tine substructures may have H-shaped cross sections. These devices seal the appendages by pinching an annular region of ostium tissue between the cover and the anchoring substructures. The shallow deployment depth of these H-shaped devices allows use of an universal device size for atrial appendages of varying lengths or depths. The devices may include remotely activated fixtures for refolding the tines for device recovery or position adjustment.
