Devices and methods for treatment of vascular aneurysms
First Claim
1. A method for filling an aneurysm sac comprising,placing a catheter configured to deliver a space-occupying device across an aneurysm cavity,placing an expandable structure across the aneurysm cavity, wherein the space-occupying device is radially outside the expandable structure during the placing of the expandable structure, andfilling the aneurysm sac with the space-occupying device;
- wherein the device comprises a first stent at the terminal end of the first longitudinal end and a second stent at the terminal end of the second longitudinal end, and wherein the first stent is the adjacent structural reinforcement element to the second stent;
wherein the space-occupying device and the catheter are substantially co-axial after the filling the aneurysm sac, and wherein the space-occupying device comprises a solid and/or solidifiable medium.

Abstract
The present invention relates to devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms found in blood vessels. In a first embodiment of the present invention, a two part prostheses, where one part is an expandable sponge structure and the other part is an expandable tubular mesh structure, is provided. In the first embodiment, the expandable sponge structure is intended to fill the aneurysm cavity to prevent further dilatation of the vessel wall by creating a buffer or barrier between the pressurized pulsating blood flow and the thinning vessel wall. In the first embodiment, the expandable tubular mesh structure is placed across the aneurysm, contacting the inner wall of healthy vessel proximal and distal to the aneurysm.

12. A method for filling an aneurysm cavity with a graft comprising an implant balloon and a longitudinal axis along a longer axis of the graft in a pre-deployment configuration, the method comprising,
positioning the graft at the aneurysm, wherein the graft is loaded radially outside a catheter, and wherein a first end of the graft is longitudinally concurrent with the catheter and wherein a second end of the graft is longitudinally concurrent with the catheter, and wherein a first stent is located at the first end of the graft, and wherein a second stent is located at the second end of the graft, and wherein the first stent is the adjacent structural reinforcement element to the second stent on the graft; -
inflating the implant balloon, wherein inflating comprises inflating with a filling medium comprising a solid and/or solidifiable medium, and detaching and removing the catheter from the graft. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for filling an aneurysm sac in a subject comprising,
placing a catheter across an aneurysm cavity, placing an expandable structure across the aneurysm cavity, and filling the aneurysm sac with a space-occupying device comprising a solid and/or solidifiable medium; -
wherein the space-occupying device is outside the catheter and inside the subject before the filling of the aneurysm sac and after placing the expandable structure; and wherein a first stent is located at a first terminal end of the space-occupying device, and wherein a second stent is located at a second terminal end of the space-occupying device, and wherein the first stent is the adjacent structural reinforcement element to the second stent on the space-occupying device.

25. A method for filling an aneurysm sac comprising,
placing a catheter across an aneurysm cavity, placing an expandable structure across the aneurysm cavity, wherein a space-occupying device is radially outside and substantially encircles the catheter during the placing the expandable structure; - and wherein a first stent is located at a first end of the expandable structure, and wherein a second stent is located at a second end of the expandable structure, and wherein the first stent is the adjacent structural reinforcement element to the second stent on the expandable structure, and
filling the aneurysm sac with the space-occupying device, wherein the space-occupying device comprises a solid and/or solidifiable medium.
- and wherein a first stent is located at a first end of the expandable structure, and wherein a second stent is located at a second end of the expandable structure, and wherein the first stent is the adjacent structural reinforcement element to the second stent on the expandable structure, and

26. A method for filling an aneurysm cavity with a graft comprising an implant balloon, a longitudinal axis along a longer axis of the graft in a pre-deployment configuration, a first stent at a first longitudinal end of the graft, a second stent at a second longitudinal end of the stent, and wherein the first stent is the longitudinally adjacent structural reinforcement element to the second stent on the graft, the method comprising:
-
positioning the graft at the aneurysm, wherein the graft is loaded radially outside and substantially longitudinally concurrent with a catheter, inflating the implant balloon, wherein inflating comprises inflating with a filling medium comprising a solid and/or solidifiable medium, and detaching and removing the catheter from the graft.
