Abstract

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.

Claims (16)

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;

wherein said anchor members of said anchor frame are at least partially covered by a membrane covering distinct from said occlusive membrane.

2. The occlusive device of claim 1 , wherein the flexible connector region comprises a spring-like configuration.

3. The occlusive device of claim 1 , wherein the flexible connector region comprises a coil.

4. The occlusive device of claim 1 , wherein the flexible connector region comprises a chain link connection.

5. The occlusive device of claim 1 , wherein the flexible connector region comprises a beaded chain connection.

6. The occlusive device of claim 1 , wherein the flexible connector region comprises a ball and socket configuration.

7. The occlusive device of claim 1 , wherein the flexible connector region comprises a flexible connector that protrudes through the first hub component or the second hub component.

8. The occlusive device of claim 1 , further comprising a constraint around the flexible connector region.

9. The occlusive device of claim 8 , wherein the first hub component, the second hub component, and the flexible connector region are covered by the membrane component.
