Embodiment Construction

[0370] Figure 1A An occlusive device 10 (or "device 10") in accordance with the present technology is shown in an expanded configuration. The occlusive device 10 may include a mesh structure 100 (or “mesh 100 ”) coupled to a coil 150 . For delivery to an aneurysm, the occlusive device 10 is configured to be placed within a delivery catheter (e.g., microcatheter) (not shown) in a compressed or low configuration such that the distal portion 100b of the mesh 100 is proximate to the delivery catheter. The distal opening will thus be released from the delivery catheter prior to the coil 150 . As a result, the coils 150 expand within and fill the interior region at least partially defined by the mesh 100 that has expanded.

[0371] The occlusive device 10 is configured to be deployed within the lumen of an aneurysm, such as a brain aneurysm, such that the mesh 100 is placed over the neck of the aneurysm while the coil 150 fills the space within the lumen of the aneurysm and displa...

Abstract

The invention discloses an occlusion device for treating intracranial aneurysm or cerebral aneurysm. The occlusion device comprises a mesh, the mesh has an expanded state and a low configuration statefor intravascular delivery to an aneurysm, the mesh includes a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state, wherein (a) the mesh is curved along its width, (b)the mesh is curved along its length, and (c) the mesh has an undulating profile across at least a portion of one or both of its length or its width. The mesh is configured to be placed within the aneurysm in the deployed state such that the mesh extends over a neck of the aneurysm.
