Abstract

Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state. The mesh may comprise a tubular mesh configured to curve along its longitudinal dimension when implanted in an aneurysm cavity.

Claims (28)

1 . A device for treating an aneurysm, the device comprising:

a mesh having a globular shape in an expanded configuration, wherein the mesh is configured to be implanted in an aneurysm in the expanded configuration, and wherein the mesh comprises:

a proximal end region, a distal end region, and a longitudinal axis extending therebetween,

an outer shell,

an inner shell having a proximal end region and a distal end region, the inner shell having a globular shape in an expanded configuration, wherein the inner shell is wholly contained by the outer shell, and

a column extending along the longitudinal axis of the mesh between a proximal end region of the column and a distal end region of the column, wherein the column is disposed within the inner shell, wherein the proximal end region of the inner shell inverts into the proximal end region of the column such that the proximal end region of the column is continuous with the proximal end region of the inner shell, wherein the proximal end region of the column is disposed at the proximal end region of the device and the distal end region of the column is disposed at the distal end region of the device such that the column is configured to provide support along the longitudinal axis of the mesh, and wherein the column terminates distally at an opening at the distal end region of the inner shell.

2 . The device of claim 1 , wherein the distal end region of the mesh forms a curved surface that is concave towards an interior region of the mesh.

3 . The device of claim 1 , wherein the outer shell and the inner shell are continuous with one another at the distal end region of the mesh.

4 . The device of claim 1 , wherein the distal end region of the mesh forms a curved surface and the opening along the curved surface.

5 . The device of claim 1 , wherein the distal end region of the mesh does not include a hub.

6 . The device of claim 1 , wherein the column extends through an interior region of the inner shell.

7 . The device of claim 1 , wherein the outer shell is globular.

8 . The device of claim 1 , wherein the inner shell is globular.

9 . The device of claim 1 , wherein the mesh is a braid.

10 . A device for treating an aneurysm, the device comprising:

a mesh having a globular shape in an expanded configuration, wherein the mesh is configured to be implanted in an aneurysm in the expanded configuration, and wherein the mesh comprises:

a proximal end region, a distal end region, and a longitudinal axis extending therebetween,

an outer shell having a proximal end region and a distal end region, wherein the distal end region of the mesh terminates at the distal end region of the outer shell, and wherein the distal end region of the outer shell forms a curved surface that is concave towards an interior region of the mesh,

an inner shell having a proximal end region and a distal end region, the inner shell having a globular shape in an expanded configuration, wherein the inner shell is wholly contained by the outer shell, and

a column extending along the longitudinal axis of the mesh between a proximal end region of the column and a distal end region of the column, wherein the column is disposed within the inner shell, wherein the mesh inverts at the proximal end region of the column such that the proximal end region of the column merges with the proximal end region of the inner shell, wherein the proximal end region of the column is disposed at the proximal end region of the device and the distal end region of the column is disposed at the distal end region of the device such that the column is configured to provide support along the longitudinal axis of the mesh, and wherein the column terminates distally at an opening at the distal end region of the inner shell.

11 . The device of claim 10 , wherein the distal end region of the mesh forms a curved surface that is concave towards an interior region of the mesh.

12 . The device of claim 10 , wherein the outer shell and the inner shell are continuous with one another at the distal end region of the mesh.

13 . The device of claim 10 , wherein the distal end region of the mesh forms a curved surface and the opening along the curved surface.

14 . The device of claim 10 , wherein the distal end region of the mesh does not include a hub.

15 . The device of claim 10 , wherein the column extends through an interior region of the inner shell.

16 . The device of claim 10 , wherein the outer shell is globular.

17 . The device of claim 10 , wherein the inner shell is globular.

18 . The device of claim 10 , wherein the mesh is a braid.
