Intrasacular Aneurysm Occlusion Device with Mesh-Filled Loops
This invention is an intrasacular aneurysm occlusion device comprising: two longitudinal wires which are inserted into an aneurysm sac; and mesh which spans between the wires. In an example, the wires can be sinusoidal. In an example, the wires can intersect multiple times to form loops which are spanned by mesh. In an example, the wires can converge and diverge multiple times to form arcuate areas between them which are spanned by mesh. In an example, the device can further comprise a third wire between the first and second wires.
1 . A device for occluding an aneurysm comprising:
a first longitudinal wire which is inserted into an aneurysm sac;
a second longitudinal wire which is inserted into the aneurysm sac, wherein the first and second longitudinal wires intersect, overlap, or connect at least three times along their longitudinal axes, forming at least two wire loops between the first and second longitudinal wires; and
a mesh material which spans the at least two loops.
