LEFT ATRIAL APPENDAGE OCCLUSIVE DEVICES

摘要

An occlusive device for left atrial appendage occlusion that has a membrane component configured to inhibit passage of blood and an expandable frame formed from a plurality of wires having a cupped occlusive component at least partially covered with the membrane component, one or more anchors with looped ends and a hub component. The occlusive device can be delivered percutaneously. The occlusive device is useful in the occlusion of the left atrial appendage.

主权项

1. An occlusive device, comprising:
a membrane component configured to inhibit passage of blood through the membrane component; an occlusive component comprising a plurality of elongate frame members arranged to form a generally disc-shaped member when the occlusion frame assumes an expanded configuration, each of the elongate frame members forming a petal of the generally disc-shaped member, wherein adjacent petals of the generally disc-shaped member at least partially overlap one another, and wherein the occlusion frame is at least partially covered by the membrane component; an anchor frame comprising a plurality of elongate anchor members arranged to form anchors for anchoring the occlusive device at an implant location; a first hub component from which the plurality of elongate frame members extend, the first hub component disposed between the occlusion frame and the anchor frame; a second hub component from which the plurality of elongate anchor members extend, the second hub component disposed between the occlusion frame and the anchor frame; a flexible connector region configured to attach the first hub component to the second hub component.
