1. A method for treating an aneurysm, comprising:
- intravascularly delivering an expandable implant to the aneurysm, the implant having a first braid and a second braid, wherein the first braid and the second braid are separate, discrete braids, and both the first braid and the second braids are flattened tubular braids;
expanding the first braid in the aneurysm to form a hollow spherical frame within the aneurysm; and
expanding the second braid within an interior portion defined by the spherical frame.

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.

12. A method for treating an aneurysm, comprising:
-
intravascularly delivering an expandable implant to the aneurysm, the implant having a first braid and a second braid, wherein the first braid and the second braid are separate, discrete braids, and at least one of the first braid and the second braid is a flattened tubular braid, and wherein a proximal end of the first braid is coupled to a distal end of the second braid via an articulating joint; expanding the first braid in the aneurysm to form a hollow frame within the aneurysm; and expanding the second braid within an interior portion defined by the frame. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method for treating an aneurysm, comprising:
-
intravascularly delivering a first expandable implant to the aneurysm, the first implant having a first braid and a second braid, wherein the first braid and the second braid are separate, discrete braids, and at least one of the first braid and the second braid is a flattened tubular braid; expanding the first braid in the aneurysm to form a first hollow spherical frame within the aneurysm; and expanding the second braid within a first interior portion defined by the first spherical frame, wherein expanding the second braid includes expanding the second braid to form a second hollow spherical frame within the first interior portion, and wherein the second spherical frame defines a second interior portion; intravascularly delivering a second implant to the aneurysm; and positioning the second implant within the second interior portion. - View Dependent Claims (21, 22, 23, 24)
