International Classification:

A61B 17/12

Abstract:

An apparatus for treating an aneurysm in a blood vessel includes an occlusion element disposed on a wire, the occlusion element including a cover for covering a neck of an aneurysm and an inner anchoring member. The cover is configured to expand from a compressed configuration in a tube to an expanded configuration when advanced out of a distal end of the tube to cover the neck of the aneurysm. The cover includes a sphere of mesh material formed into a hemisphere including two layers of mesh that is formed by folding a top portion of the sphere into a bottom portion of the sphere. The inner anchoring member is coupled to and extends from the second surface of the cover and is configured to contact an interior surface of the aneurysm. The inner anchoring member may be a cylindrical stem extending from a central portion of the cover.

Abstract:

A vaso-occlusive system configured for embolizing an aneurysm, includes an implantable vaso-occlusive device coupled to a distal end of an elongate pusher and having a collapsed delivery configuration and an expanded, deployed configuration, wherein the vaso-occlusive device includes a proximal end configured to seat against the aneurysm adjacent the neck of the aneurysm, a distal end configured to extend in the sac and away from the neck of the aneurysm, and a central longitudinal axis, and wherein the vaso-occlusive device is configured to be releasably coupled to the distal end of the pusher at a releasable joint including either one or both of the configurations in the list consisting of: (1) the distal end of the pusher extends from the releasable joint at an angle formed with the central longitudinal axis of between about 30 degrees and about 120 degrees, and (2) the releasable joint is coupled at a location on the proximal end of the vaso-occlusive device that is radially offset from the central longitudinal axis.

Abstract:

A stent retriever for removing a thrombus from a blood vessel includes a body portion formed by a mesh sheet formed into a substantially cylindrical shape. The mesh sheet includes a pair of undulating wire members coupled to a connecting member, each wire member having a plurality of protrusions and a plurality of recesses. The plurality of protrusions on a first side of the mesh sheet are offset from the plurality of protrusions on a second side of the mesh sheet such that when the mesh sheet is formed into the substantially cylindrical shape, the wire members are disposed in an interlocking arrangement such that the recesses on the first side receive at least portions of the protrusions on the second side. At least one of the plurality of protrusions includes a subprotrusion formed in the wire member to increase the mesh density of the stent retriever.
