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.

Patent number: 10898201Abstract: 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: GrantFiled: August 14, 2017Date of Patent: January 26, 2021Assignee: Nellix, Inc.Inventors: Steven L. Herbowy, Michael A. Evans, Anant Kumar, K. T. Venkateswara Rao, Matthew R. Hellewell, Gil Laroya

Patent number: 10864098Abstract: 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: GrantFiled: August 21, 2017Date of Patent: December 15, 2020Assignee: Nellix, Inc.Inventors: Michael A. Evans, Gwendolyn A.

Patent number: 9814612Abstract: A positioning anchor is provided for a stent-graft for implantation to treat a damaged body lumen. The positioning anchor is generally tubular surrounding a primary fluid conduit. Arms extend laterally from the generally tubular structure of the anchor surrounding lateral fluid conduits. The form of these arms is preferably custom configured to match a particular patient's luminal geometry. The anchor thus fits within the luminal geometry to remain in a desired fixed position for implantation of the anchor and any stent-graft coupled to the anchor. The anchor is most preferably formed with two walls having a void therebetween which can be filled with fixation media to further secure the anchor at the desired implantation site. A lumen shaper balloon and delivery catheter are also disclosed for proper delivery, expansion and inflation of the positioning anchor and stent-graft elements according to this invention.Type: GrantFiled: October 21, 2015Date of Patent: November 14, 2017Assignee: Nellix, Inc.Inventors: Charles S. Taylor, Christopher Zarins, Robert A. Geshlider, Dwight P. Morejohn, Peter Johansson, Susan W. Vican, James T. McKinley

Patent number: 8945199Abstract: 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: GrantFiled: June 4, 2009Date of Patent: February 3, 2015Assignee: Nellix, Inc.Inventors: Raj P.
