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. The devices may include remotely activated fixtures for refolding the tines for device recovery or position adjustment.

Abstract: Implant devices for modifying blood flow between an atrial appendage and its associated atrium, are customized for use in subject atrial appendages. The implant devices are tailored to uniquely match individual anatomical characteristics. Cardiac imaging techniques are used to obtain data on the size, shape and orientation of the subject atrial appendage. The raw imaging data is electronically processed using computer modeling to obtain multi-dimensional anatomical images of the subject atrial appendages. Three-dimensional computer aided design tools are used to generate customized device designs from the anatomical images of the subject atrial appendages.

Abstract: Instrumentation for percutaneous delivery of blood filtration devices to atrial appendages includes a curved access sheath (510) and a delivery tube (220). The curved access sheath is coursed through the patient's vasculature to gain transseptal access to a left atrial appendage (11). A compressed filter device (700) attached to a tether wire (410) is loaded in the delivery tube (220). The loaded delivery tube is advanced through the pre-positioned access sheath to place the device in a deployment position. The access sheath (510) and the delivery tube (220) can be mechanically locked and moved together to place the device in a suitable deployment position. The device (700) is deployed by expelling it from the delivery tube (220) either by retracting the delivery tube over the tether wire, or by moving the tether wire forward through the delivery tube. The expelled device, which is not constrained by the delivery tube walls, self expands to its useful size in the subject atrial appendage. A filter membrane (710) in the deployed extends across the appendage ostium (13) to filter blood flow through the ostium. The filter membrane is configured to present a flat surface to atrial blood flow past the ostium.

Abstract: The invention provides a delivery system for placing devices in atrial appendages. The system includes a catheterization apparatus having a tubular structure with one or more nested tubes, wires, and shafts. The tubes establish a passageway for moving a device through a body's vasculature and heart into an atrial appendage. An expandagle positioning guide is disposed on the distal end of a tube passing through the apparatus. The positioning guide is expanded in situ to engage atrial wall surfaces proximate to the atrial appendage for mechanical stabilizes the device delivery passageway. A shaft passing through the tubes transports the device through the passageway to the atrial appendage.

Abstract: Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure attached to the filtering membrane which retains the filtering membrane in position across the ostium of the left atrial appendage by permanently engaging a portion of the interior wall of the left atrial appendage. The support structure may be radially expandable from a first configuration to a second configuration which engages the ostium or the interior wall of the left atrial appendage. The filtering membrane may define an opening therethrough that is configured to expand from a first size which inhibits the passage of thrombus therethrough to a second size which allows an interventional device, e.g., an expansion balloon, to pass therethrough, and wherein the opening is resiliently biased towards the first size.
