Occlusive devices
An occlusive device includes a frame element having a distal end and a proximal end, and a delivery configuration and a deployed configuration. The occlusive device also includes an occlusive face having a peripheral edge, where the occlusive face positioned toward the proximal end of the frame element. The occlusive device also includes at least one anchor positioned at the peripheral edge of the occlusive face, where the at least one anchor extends at an acute angle to the peripheral edge of the occlusive face.
1. An occlusive device comprising:
an engagement feature;
a plurality of elongate members extending from different locations about a perimeter of the engagement feature; and
a membrane arranged on the plurality of elongate members, the membrane and the plurality of elongate members forming:
an occlusive face having an outer perimeter, the occlusive face including first portions of the plurality of elongate members that each include a common radial curved pattern relative to the outer perimeter of the occlusive face with at least one bend in each of the plurality of elongate members altering curvature from one of a clockwise direction or a counterclockwise direction, and
a body portion extending distally relative to the occlusive face to a distal end, the body portion defining a taper toward the distal end and including second portions of the plurality of elongate members converging toward one another to define the taper.
2. The occlusive device of claim 1 , wherein the occlusive face is substantially planar.
3. The occlusive device of claim 1 , wherein the occlusive face is conformable in a deployed configuration.
4. The occlusive device of claim 3 , wherein the occlusive face is conformable to a shape of an ostium of a portion of anatomy in the deployed configuration.
5. The occlusive device of claim 1 , wherein the body portion is conformable in a deployed configuration.
6. The occlusive device of claim 5 , wherein the body portion is conformable to a shape of a portion of anatomy in the deployed configuration.
7. The occlusive device of claim 1 , wherein the occlusive face is conformable to a shape of an ostium of an atrial appendage and the body portion is conformable to the atrial appendage.
8. The occlusive device of claim 1 , wherein the engagement feature comprises an eyelet.
9. A device for occluding an appendage in a patient, the device comprising:
a membrane arranged on a plurality of elongate members, the membrane and the plurality of elongate members forming:
an occlusive face configured to conform to an ostium of the appendage, the occlusive face having an outer perimeter that includes first portions of the plurality of elongate members that each include a common radial curved pattern relative to the outer perimeter of the occlusive face with at least one bend in each of the plurality of elongate members altering curvature from one of a clockwise direction or a counterclockwise direction, and
a body portion configured to conform to the appendage and defining a taper from the occlusive face including second portions of the plurality of elongate members converging toward one another to define the taper.
10. The device of claim 9 , wherein the occlusive face is substantially planar.
11. The device of claim 9 , further comprising an anchor positioned on an exterior portion of the body portion.
12. The device of claim 9 , wherein the membrane is configured to induce rapid tissue ingrowth that occludes passage of blood through the membrane.
13. The device of claim 9 , wherein the membrane and the plurality of elongate members include a delivery configuration and a deployed configuration, and the membrane and the plurality of elongate members are configured to collapse to the delivery configuration upon insertion into a component of a delivery system.
14. The device of claim 9 , wherein the first portions of the plurality of elongate members include a common curvature.
15. The device of claim 9 , wherein the first portions of the plurality of elongate members are non-intersecting.
16. The device of claim 9 , wherein the first portions of the plurality of elongate members are unconnected.
17. The device of claim 9 , wherein the appendage of the patient is a left atrial appendage, and the plurality of elongate members are configured to fan out to form occlusive features and anchoring features, and the anchoring features engage tissue near an ostium of the left atrial appendage.
18. A method of occluding a vessel, comprising:
delivering an occlusive device to a delivery site, the occlusive device including a plurality of elongate members extending from different locations about a perimeter of an engagement feature, and a membrane arranged on the plurality of elongate members, the membrane and the plurality of elongate members forming: an occlusive face having an outer perimeter, the occlusive face including first portions of the plurality of elongate members that each include a common radial curved pattern relative to the outer perimeter of the occlusive face with at least one bend in each of the plurality of elongate members altering curvature from one of a clockwise direction or a counterclockwise direction, and a body portion extending distally relative to the occlusive face to a distal end, the body portion defining a taper toward the distal end and including second portions of the plurality of elongate members converging toward one another to define the taper; and
deploying the occlusive device at the delivery site.
19. The method of claim 18 , wherein the delivery site is a left atrial appendage.
20. The method of claim 18 , further comprising configuring the occlusive device in a delivery configuration and advancing the occlusive device to the delivery site.
