Method for left atrial appendage occlusion
View Patent ↗Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes a pumpable injectable material and a retention member having a tissue penetrating shaft which extends from a proximal end of the device to a distal end of the device.
1. An implantable occlusion device for permanent implantation within the left atrial appendage, comprising:
a pumpable injectable material which conforms to the left atrial appendage;
wherein the occlusion device further comprises a retention element;
wherein the retention element is a tissue penetrating shaft;
wherein the tissue penetrating shaft has a helical distal end;
wherein the tissue penetrating shaft extends from a proximal end of the device to a distal end of the device.
2. The implantable occlusion device of claim 1 wherein the retention element comprises a radially extending barrier at the proximal end of the device.
3. The implantable occlusion device of claim 2 wherein the barrier is coupled to the tissue penetrating shaft with a rotational coupling that allows rotation of the shaft with respect to the barrier.
4. The implantable occlusion device of claim 2 wherein the barrier is secured to a resilient outer rim.
5. The implantable occlusion device of claim 4 wherein the barrier protrudes proximally from the outer rim.
6. The implantable occlusion device of claim 1 wherein the retention element comprises a plurality of members extending radially from the proximal end of the device.
7. The implantable occlusion device of claim 1 wherein the retention element comprises an occlusive coil.
8. The implantable occlusion device of claim 7 wherein the occlusive coil is deployed in a randomly oriented configuration.
