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 one embodiment, a system for treating an aneurysm is disclosed. The system comprises a catheter delivery system, an expandable foam configured to pass through the catheter delivery system, and a stent having a first end and a second end. The stent is configured to extend across the aneurysm. The expandable foam is configured to expand in the aneurysm when exposed to a fluid.

9. A system for treating an aneurysm comprising:
-
a catheter delivery system; and an expandable filler and an outer skin, wherein the expandable filler comprises a compressed configuration when passing through the catheter delivery system, wherein the expandable filler expands into an expanded configuration when delivered in the aneurysm, wherein the outer skin has a first deployed configuration and a second deployed configuration, and wherein the outer skin is closer to a wall of the aneurysm when the outer skin is in the second deployed configuration than when the outer skin is in the first deployed configuration, wherein when the outer skin is in the second deployed configuration, the expandable filler is a continuous foam structure that is foldable between the outer skin and a stent. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for treating an aneurysm comprising:
-
a catheter delivery system having a tip and a communication port; and an expandable filler and an outer skin, wherein when in a deployed configuration, the expandable filler is delivered through the tip of the catheter delivery system and expands into an expanded configuration inside the aneurysm, and wherein when in the deployed configuration, a portion of the outer skin contacts the expandable filler and a wall of the aneurysm, wherein the communication port terminates at an entrance of an expandable space, wherein the expandable filler is passable through the communication port from the catheter delivery system to the expandable space, and wherein the communication port is in communication with a lumen of a stent. - View Dependent Claims (18, 19, 20)
