Embolization particulates for occluding a blood vessel
First Claim
1. Embolization particulates suitable for occluding a blood vessel, the embolization particulates comprising:
- a plurality of embolization beads, each of said embolization beads comprises;
a plurality of outwardly protruding portions, wherein, upon a first one and a second one of said embolization beads accumulating against a boundary of the blood vessel, said protruding portions of said first embolization bead are configured to intermesh with said protruding portions of said second embolization bead, so as to occlude the blood vessel;
wherein said embolization beads are formed with a tetrapod shape or a tetrahedron shape; and
wherein the embolization beads are configured to resist aggregation prior to reaching the blood vessel, and to aggregate within the blood vessel once delivered thereto.

Abstract
Injectable embolization particulates (e.g., particles, microstructures, beads) employed in embolization procedures, for facilitating blood vessel occlusion. Exemplary embolization particulates for occluding a blood vessel include a plurality of embolization beads, each bead having a plurality of outwardly protruding portions, wherein, upon a first one and a second one of the beads accumulating against a boundary of the blood vessel, protruding portions of the first bead are configured to intermesh with protruding portions of the second bead, so as to occlude the blood vessel. Also disclosed are compositions of embolization particulates including a plurality of shaped embolization beads, and methods for embolizing or occluding a blood vessel using embolization particulates or compositions thereof. Embolization particulates have particular shapes for facilitating blood vessel occlusion while preventing or diminishing back flow (reflux) of embolic material, and may be coated or impregnated with therapeutic agents or radioactive isotopes, for increasing desirable therapeutic effects.
