Claim 0:
1. An intrasaccular aneurysm occlusion device comprising:
a first mesh or net which is configured to be inserted and expanded within an aneurysm sac, wherein the first mesh or net has a first proximal-to-distal length, wherein the first mesh or net has a first stiffness level, and wherein the first mesh or net has a first elasticity level; and
a second mesh or net which is in contact with a proximal portion of the first mesh or net, wherein the second mesh or net has a second proximal-to-distal length, wherein the second mesh or net has a second stiffness level, wherein the second mesh or net has a second elasticity level, wherein the second proximal-to-distal length is less than the first proximal-to-distal length, and wherein the second stiffness level is greater than the first stiffness level and/or the second elasticity level is less than the first elasticity level;
wherein the device further comprises a proximal opening in one or both meshes or nets through which embolic material is inserted;
wherein the embolic material comprises one or more string-of-pearls embolic strands; wherein a string-of-pearls embolic strand further comprises embolic pieces which are longitudinally linked by one or more filaments; wherein the embolic pieces are balls, beads, or three-dimensional polygonal pieces; and wherein the filaments are strings, threads, sutures, wires, or coils; and
wherein durometer levels of embolic pieces along the string-of-pearls embolic strand become lower as one progresses from a distal end to a proximal end of the strand.
