Devices and methods for the treatment of vascular defects
First Claim
1. A device for treating an aneurysm of a human patient, the device comprising:
- an implant configured to be positioned within the aneurysm, the implant having a collapsed configuration and an expanded configuration, wherein, in the collapsed configuration, the implant is configured to be contained within a delivery device, wherein the implant includesa proximal portion configured to be removably coupled to a delivery device;
a first braid having a proximal region fixed at the proximal portion and a distal region opposite the proximal region along the length of the first braid;
a second braid having a proximal region fixed at the proximal portion and a distal region opposite the proximal region along the length of the second braid;
wherein at least one of the first braid and the second braid comprises a flattened tubular braid configured to form a three-dimensional structure when the implant is in the expanded configuration; and
wherein, when the implant is in the collapsed configuration, the first braid and the second braid are coextensive along at least a portion of each other.

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.
