Devices and methods for the treatment of vascular defects
First Claim
1. An implant configured to be positioned within an aneurysm, the implant comprising:
- an expandable mesh formed and a tubular braid flattened along at least a portion of its longitudinal axis such that opposing sidewalls of the tubular mesh are urged towards one another, the mesh having an elongated state and a deployed state, wherein—
when the mesh is in the elongated state, the mesh is radially compacted and configured to be contained in a delivery device, andwhen the mesh is in the deployed state, the mesh has a narrow portion and at least first and second flattened wide portions, wherein the narrow portion is between the first and second wide portions along a length of the mesh.

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.
