Publication number: 20210212699Abstract: A system for treating an aneurysm comprises an elongate flexible shaft and an expandable member. An expandable scaffold is disposed over the expandable member and may be expanded from a collapsed configuration to an expanded configuration. A double-walled filling structure is disposed over the scaffold and has an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filing medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow. In the expanded configuration the scaffold engages the inner wall of the filling structure. A tether is releasably coupled with the filling structure and the flexible shaft thereby constraining axial movement of the structures relative to each other.Type: ApplicationFiled: January 25, 2021Publication date: July 15, 2021Inventors: Steven L. Herbowy, Michael A. Evans, Anant Kumar, K.T. Venkateswara Rao, Matthew R. Hellewell, Gil Laroya

Patent number: 8182525Abstract: Aneurysms are treated by filling a double-walled filling structure with a curable medium. The structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. The filling structures are preferably used in pairs for providing flow into the iliac arteries when treating abdominal aortic aneurysm.Type: GrantFiled: April 9, 2009Date of Patent: May 22, 2012Assignee: Endologix, Inc.Inventors: Steven L. Herbowy, Matthew R. Hellewell, K. T. Venkateswara Rao, Michael A. Evans, Thomas Howell, Gwendolyn A. Watanabe, Bhupendra Shah, James McKinley
