Abstract
This invention is an intrasaccular aneurysm occlusion device with an expandable mesh which is inserted and expanded within an aneurysm sac. The expandable mesh can be steered in a selected direction and/or expanded in a radially-asymmetric manner by moving a joint, sliding catheter sections, pulling or pushing wires, detaching constraints, or filling chambers in the mesh with embolic material. There can be a plurality of non-central openings with remotely-controllable valves in the expandable mesh through which embolic material is inserted into the aneurysm sac.
Claims20
An intrasaccular aneurysm occlusion device comprising:
- an expandable mesh that is configured to be inserted into an aneurysm sac;
- embolic members or material that are inserted into the aneurysm sac;
- and
- a catheter through which the expandable mesh and/or the embolic members or material are delivered to the aneurysm sac.
An intrasaccular aneurysm occlusion device comprising:
- a flexible net or mesh that is inserted into an aneurysm sac;
- an expandable band or ring that is inserted into the aneurysm sac, wherein the expandable band or ring spans a circumference of the flexible net or mesh;
- embolic members or material which are inserted into the flexible net or mesh;
- and
- a catheter through which the flexible net or mesh, the expandable band or ring, and/or the embolic members or material are delivered to the aneurysm sac.
An intrasaccular aneurysm occlusion device comprising:
- an expandable mesh that is inserted into an aneurysm sac;
- wherein the expandable mesh is radially expanded within the aneurysm sac at a first time into a first configuration having a convex shape;
- wherein the expandable mesh is collapsed, compressed, and/or inverted within the aneurysm sac at a second time into a second configuration having a concave shape;
- wherein the expandable mesh further comprises a flexible annular section or band which spans a circumference of the expandable mesh;
- wherein the flexible annular section of band is more flexible and/or elastic than the rest of the expandable mesh;
- wherein a first portion of the expandable mesh is distal relative to the flexible annular section or band in the first configuration;
- wherein a second portion of the expandable mesh is proximal relative to the flexible annular section or band in the first configuration;
- wherein the first portion of the expandable mesh is collapsed, compressed, and/or inverted into the second portion of the expandable mesh when the expandable mesh is changed from the first configuration to the second configuration;
- wherein both the first portion of the expandable mesh and the second portion of the expandable mesh are proximal relative to the flexible annular section or band in the second configuration;
- embolic members or material that are inserted into portions of the aneurysm sac which are distal relative to the expandable mesh;
- wherein pressure from accumulation of the embolic members or material collapses, compresses, and/or inverts the first portion of the expandable mesh into the second portion of the expandable mesh;
- and
- one or more catheters which deliver the expandable mesh and/or the embolic members or material to the aneurysm sac.
