Abstract

An intrasacular aneurysm occlusion device can be a peanut, hourglass, and/or hyperbolic shaped mesh which is inserted and expanded within an aneurysm sac. The proximal lobe of the device reduces blood flow into the sac through the aneurysm neck and the distal lobe of the device contacts the dome of the sac so as to keep the proximal lobe from shifting. The narrow center portion of the peanut, hourglass, or hyperbolic mesh can bend so that the device at least partially conforms to the interior of an irregularly-shaped aneurysm sac.

Claims (10)

1 . An aneurysm occlusion device comprising:

a peanut or hourglass shaped mesh which is configured to be inserted into an aneurysm;

wherein the mesh further comprises a distal portion, wherein the distal portion has a first thickness; and

wherein the mesh further comprises a proximal portion which is configured to span the aneurysm neck, wherein the proximal portion has a second thickness, and wherein the second thickness is greater than the first thickness.

2 . An aneurysm occlusion device comprising:

a peanut or hourglass shaped distal mesh which is configured to be inserted into an aneurysm sac, wherein the distal mesh centroid is a first distance from the aneurysm neck; and

a bowl shaped proximal mesh which is configured to be inserted into the aneurysm sac, wherein the proximal mesh centroid is a second distance from the aneurysm neck, wherein the second distance is less than the first distance, wherein the proximal mesh spans the aneurysm neck, and wherein the proximal mesh is connected to the distal mesh.

3 . An aneurysm occlusion device comprising:

a distal mesh which is configured to be inserted into an aneurysm sac, wherein the distal mesh is convex, and wherein the distal mesh centroid is a first distance from the aneurysm neck; and

a proximal mesh which is configured to be inserted into the aneurysm sac, wherein the proximal mesh is concave, wherein the proximal mesh centroid is a second distance from the aneurysm neck, wherein the second distance is less than the first distance, wherein the proximal mesh spans the aneurysm neck, and wherein the proximal mesh is axially-aligned with the distal mesh.
