Patent number: 12193676Abstract: 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: January 25, 2021Date of Patent: January 14, 2025Assignee: Nellix, Inc.Inventors: Steven L. Herbowy, Michael A. Evans, Anant Kumar, K. T. Venkateswara Rao, Matthew R. Hellewell, Gil Laroya

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

Publication number: 20230243102Abstract: A composition for improving softness of tissue and/or towel products includes lignocellulosic fibers; water; and a hydrophobic softener that includes the reaction product of: (1) at least one di- and/or poly-amine, (2) at least one chain extender having at least two carboxyl groups; and (3) at least one hydrophobic end-capper. The reaction product comprises a hydrophobic substitution of at least about 25 mole percent of the hydrophobic end-capper based on a total number of moles of active amine sites of the reaction product. In addition, a method of improving softness of tissue and/or towel products includes combining the lignocellulosic fibers, the water, and the hydrophobic softener; and creating the tissue and/or towel products.Type: ApplicationFiled: January 31, 2023Publication date: August 3, 2023Applicant: SOLENIS TECHNOLOGIES, L.P.Inventors: Michael A. Evans, Clement L. Brungardt, Patrick R. Kovacs, David A. Gerstenhaber

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

Patent number: 11523618Abstract: Disclosed is a conveyor system including a first conveyor leading to an inspection point, the first conveyor including a diversion mechanism configured to divert an object based on failing to meet an inspection parameter. The system includes a second conveyor configured to transport a container configured to receive the object from the diversion mechanism. A control module is configured to co-register an image of the object captured at the inspection point with container ID data of the container.Type: GrantFiled: September 30, 2019Date of Patent: December 13, 2022Assignee: METTLER-TOLEDO, LLCInventors: Norbert Hartwig, Michael A. Evans, Kristofer Loper, Christopher Sisemore

Patent number: 11209899Abstract: A technique for adjusting the brightness values of images to be displayed on a stereoscopic head mounted display is provided herein. This technique improves the perceived dynamic range of the head mounted display by dynamically adjusting the pixel intensities (also known generally as “exposure”) of the images presented on the head mounted display based on a detected gaze direction. The head mounted display includes an eye tracker that is able to sense the gaze directions of the eyes. The eye tracker, head mounted display, or a processor of a computer system receives this information, determines an intersection point of the eye gaze and a screen within the head mounted display and identifies a gaze area around this intersection point. Using this gaze area, the processing system adjusts the pixel intensities of an image displayed on the screen based on the intensities of the pixels within the gaze area.Type: GrantFiled: November 8, 2017Date of Patent: December 28, 2021Assignee: Advanced Micro Devices, Inc.Inventors: Michael A.

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: 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.
