Devices and methods for the treatment of vascular defects
First Claim
1. An occlusive device configured to be positioned within an aneurysm, the device comprising:
- a mesh having a proximal terminus and a distal terminus opposite the proximal terminus along the length of the mesh; and
an attachment mechanism at the distal terminus of the mesh,wherein the mesh has a preset shape such that, at least when the mesh is in a deployed state, the mesh includes;
a flattened broad portion having a first width,a curved intermediate portion extending distally from the flattened broad portion, the curved intermediate portion having a second width less than the first width, andan elongated narrow portion extending distally from the curved intermediate portion and terminating at the attachment mechanism, wherein the elongated narrow portion is positioned at an angle relative to the flattened broad portion.

Abstract
Devices and methods for treating vascular defects, such as, for example, balloon-type aneurysms, are described herein. In one embodiment, an apparatus includes an insertion portion and an expandable implant. The expandable implant is configured to be deployed in an aneurysm and is coupled to the insertion portion. The expandable implant has a first portion and a second portion coupled to the first portion. The expandable implant is movable between a first configuration in which the first portion and the second portion are substantially linearly aligned and a second configuration in which the second portion at least partially overlaps the first portion.

11. An intrasaccular occlusion device configured to be positioned within a cerebral aneurysm, the device comprising:
-
a mesh having a proximal terminus and a distal terminus opposite the proximal terminus along the length of the mesh; and an attachment mechanism at the distal terminus of the mesh, wherein the mesh has a preset shape such that, at least when the mesh is in a deployed state, the mesh further includes; a plurality of flattened broad portions, a curved distal portion extending distally from a distal terminus of the distal-most flattened broad portion, the curved distal portion having a width that is less than a width of the distal-most flattened broad portion, and an elongated narrow portion extending distally from the curved distal portion and terminating at the attachment mechanism, wherein the elongated narrow portion is positioned at an angle relative to the distal-most flattened broad portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
