Patent number: 11957608Abstract: Aneurysms are treated by filling at least one double-walled filling structure with a curable medium within the aneurysm. The filling structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Scaffolds are placed into the tubular lumens in order to help maintain the shape, anchor the filling structures in place, and provide improved blood flow transition into and out of the tubular lumens.Type: GrantFiled: February 1, 2021Date of Patent: April 16, 2024Assignee: Nellix, Inc.Inventors: Michael A. Evans, Gwendolyn A. Watanabe, Amy Lee, Steven L. Herbowy

Patent number: 11596413Abstract: Aneurysms are treated by placing a scaffold across an aneurysmal sac to provide a blood flow lumen therethrough. An aneurysmal space surrounding the scaffold is filled with one or more expandable structures which are simultaneously or sequentially expanded to fill the aneurysmal space and reduce the risk of endoluminal leaks and scaffold migration. The expandable structures are typically inflatable and delivered by delivery catheter, optionally with an inflation tube or structure attached to the expandable structure.Type: GrantFiled: June 12, 2020Date of Patent: March 7, 2023Assignee: Endologix LLCInventors: Michael A. Evans, Gwendolyn A. Watanabe, Amy Lee, Steven L. Herbowy

Publication number: 20210369438Abstract: A system for treating an aneurysm comprises at least a first double-walled filling structure having an outer wall and an inner wall and the filling structure is adapted to be filled with a hardenable fluid filling medium so that the outer wall conforms to the inside surface of the aneurysm and the inner surface forms a generally tubular lumen to provide blood flow. The first filling structure comprises a sealing feature which forms a fluid seal between the filling structure and the aneurysm or an adjacent endograft when the filling structure is filled with the hardenable fluid filling medium, thereby minimizing or preventing blood flow downstream of the seal.Type: ApplicationFiled: August 16, 2021Publication date: December 2, 2021Inventors: Raj P. Ganpath, Amy Lee, Craig Rosenberg, Sherwin Llamido, Steven L. Herbowy, Michael A. Evans, Thomas A. Howell, Charles S. Taylor, K.T. Venkateswara Rao

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

Publication number: 20210093473Abstract: Embodiments provide methods and systems for treating aneurysms using filling structures filled with a curable medium An embodiment of a method comprises positioning at least one double-walled filling structure across the aneurysm and filling the structure(s) with a filling medium so that an outer wall conforms to the inside of the aneurysm and an inner wall forms a generally tubular lumen to provide for blood flow. The lumen is supported with a balloon or other expandable device while and/or after filling. The pressure within the structure and/or in the space between an external wall of the structure and the aneurysm wall is monitored and a flow of the medium into the structure is controlled responsive to the pressure. The pressure can also be used to determine a filling endpoint. The medium is hardened while the lumen remains supported by the balloon. The balloon is then removed after the medium hardens.Type: ApplicationFiled: December 11, 2020Publication date: April 1, 2021Inventors: Michael A. Evans, Gwendolyn A. Watanabe, Amy Lee, Steven L.
