Publication number: 20240130877Abstract: A method of deploying a multibranch stent graft at a target site having a main lumen and a first branch lumen is provided. The method includes advancing a catheter including a main body having a first portion and a second portion, the main body defining a first portal being pre-cannulated with a first guide member, partially deploying the first portion of the main body, advancing a first sheath along the first guide member through the first portal, advancing a first articulatable wire through the first sheath, positioning the first articulatable wire into a first branch lumen of the target site, partially deploying the second portion of the main body, fully deploying the first portion and the second portion of the main body, advancing a first side branch body along the first articulatable wire into the first branch lumen, and deploying the first side branch body in the first branch lumen.Type: ApplicationFiled: February 22, 2022Publication date: April 25, 2024Inventors: Merrill J. Birdno, Jerald M. Crawley, Kehinde A. Majolagbe, Adam H. Power, Brandon C. Short, Derek M. Ward, Patrick S. Young

Publication number: 20240122732Abstract: A multibranch implantable device including a main body including a tubular element having wall defining a main lumen, the tubular element having a first end defining a first opening into the main lumen and a second end defining a second opening in the main lumen, the tubular element including at least one side branch portal defining an aperture through the wall between the first longitudinal end and the second longitudinal end of the tubular element and at least one secondary body defining a secondary lumen, the at least one secondary body operable to be deployed with a portion of the secondary body positioned in the at least one side branch portal of the main body.Type: ApplicationFiled: February 22, 2022Publication date: April 18, 2024Inventors: Merrill J. Birdno, Jerald M. Crawley, Kehinde A. Majolagbe, Brandon C. Short, Derek M. Ward, Patrick S. Young

Publication number: 20230255743Abstract: An implantable device comprising a main endoprosthesis configured for implantation in a vessel, the main endoprosthesis including at least one side portal, a first side-branch endoprosthesis configured to be deployed within the main endoprosthesis and direct flow through a first side-branch vessel via the at least one side portal, a second side-branch endoprosthesis configured to be deployed within the main endoprosthesis and direct flow through a second branch vessel via the at least one side portal, and wherein when not containing a side-branch endoprosthesis the at least one side portal comprises a side channel without fluid separation.Type: ApplicationFiled: June 10, 2021Publication date: August 17, 2023Inventors: Merrill J. Birdno, Bret J. Kilgrow, Kehinde Adeitunu Majolagbe, Derek M. Ward, Patrick S. Young

Publication number: 20230028428Abstract: Systems and methods for stimulation of neurological tissue and generation stimulation trains with temporal patterns of stimulation, in which the interval between electrical pulses (the inter-pulse intervals) changes or varies over time. The features of the stimulation trains may be selected and arranged algorithmically to by clinical trial. These stimulation trains are generated to target a specific neurological disorder, by arranging sets of features which reduce symptoms of that neurological disorder into a pattern which is effective at reducing those symptoms while maintaining or reducing power consumption versus regular stimulation signals. Compared to conventional continuous, high rate pulse trains having regular (i.e., constant) inter-pulse intervals, the non-regular (i.e., not constant) pulse patterns or trains that embody features of the invention provide increased efficacy and/or a lower than average frequency.Type: ApplicationFiled: September 28, 2022Publication date: January 26, 2023Inventors: Warren M. Grill, David T. Brocker, Merrill J. Birdno

Patent number: 11541204Abstract: This disclosure relates generally to treatment programs utilizing expansion elements, such as those associated with occlusion and therapeutic agent delivery devices, systems, and methods. In some more specific examples, treatment programs include expansion-contraction cycles at a pre-selected frequency profile configured to treat a particular condition, such as calcification of an arterial conduit, for example.Type: GrantFiled: September 25, 2019Date of Patent: January 3, 2023Assignee: W. L. Gore & Associates, Inc.Inventors: Merrill J. Birdno, Mike A. Schmieder, Edward E. Shaw, Brandon C. Short, Alireza Mashal, Matthew B. DeNardo, Franck J. Rubiconi, Linda M. Donoghue, Serge C. Roux

Publication number: 20220280759Abstract: Described embodiments are directed to a device for delivery of activatable compounds to a patients lumen, such as in transcatheter procedures. More specifically, described embodiments are directed toward delivery devices operable to deliver the activatable compounds and to activate the compounds by light. Such delivery devices include a balloon (14) having a treatment zone (16) for activatable compound delivery and/or activation and non-treatment zones (18) that block activatable compound delivery and/or activation for controlled delivery and activation of the activatable compounds.Type: ApplicationFiled: August 7, 2020Publication date: September 8, 2022Inventors: Merrill J. Birdno, Michael R. Broyles, Jeffrey J. Honer, Christopher Hyzin, Brandon C. Short, Jared S. Nelson
