Publication number: 20230081550Abstract: The techniques of this disclosure generally relate to a modular assembly including first and second stent-grafts. The first stent-graft includes a body portion having a first diameter and a waist portion having a second diameter less than the first diameter. The waist portion is at a distal end of the first stent-graft. The second stent-graft includes a captured proximal portion configured to be located within the first stent-graft. The captured proximal portion includes a seated portion configured to be located proximal to the waist portion. The seated portion has a third diameter greater than the second diameter to form a mechanical interlock between the first stent-graft and the second stent-graft.Type: ApplicationFiled: September 22, 2022Publication date: March 16, 2023Inventors: Haley King, Adam Shipley, Timothy Bertini, Ana Zavala

Publication number: 20220273418Abstract: A staged-deployment stent graft assembly. A main stent graft has a sacrificial port extending therefrom. The stent graft has a compressed state and an expanded state. The staged-deployment stent graft assembly also includes an internal stent cuff located within the stent graft. The internal stent cuff has a constricted state and a non-constricted state. The internal stent cuff may be biased to expand from the constricted state to the non-constricted state to close the sacrificial port when the main stent graft is in the expanded state. The assembly also includes a filament structure maintaining the internal stent cuff in the constricted state. The assembly further includes a release configured to manipulate the filament structure to transition the internal stent cuff from the constricted state to the non-constricted state to close the sacrificial port when the main stent graft is in the expanded state.Type: ApplicationFiled: May 16, 2022Publication date: September 1, 2022Inventors: Adam SHIPLEY, Timothy BERTINI, Keith PERKINS, Gian PELLEGRINI

Publication number: 20220211526Abstract: The techniques of this disclosure generally relate to an iliac branch device having an external iliac body, a common iliac branch, and an internal iliac branch. A diameter of the proximal opening of the common iliac branch is greater than a diameter of a distal opening of the external iliac body. The iliac branch device is configured to be deployed without going up and over the aortic bifurcation and without using some form of supra-aortic antegrade access such as through brachial or axillary artery access. This simplifies the procedure and reduces procedure time thus maximizing the success rate of the procedure and allows the procedure to be performed on a broad patient population.Type: ApplicationFiled: March 22, 2022Publication date: July 7, 2022Inventors: Timothy Bertini, Adam Shipley

Patent number: 11357612Abstract: A stent graft assembly with a sacrificial entry/exit port is disclosed. A first sacrificial port extends from a first branch stent graft and is configured to face a second branch stent graft when the stent graft assembly is in an expanded configuration. Likewise, a second sacrificial port can be provided, and can extend from the second branch stent graft and configured to face the first branch stent graft when the stent graft assembly is in the expanded configuration. The first and optional second sacrificial ports are configured to transition between (i) an open configuration to enable a guidewire or other surgical tool to pass from the first branch stent graft to the second branch stent graft while bypassing the main body, and (ii) a closed configuration to inhibit blood flow therethrough.Type: GrantFiled: July 16, 2020Date of Patent: June 14, 2022Assignee: Medtronic Vascular, Inc.Inventors: Adam Shipley, Timothy Bertini, Keith Perkins, Gian Pellegrini

Publication number: 20210401598Abstract: Methods, systems, devices and apparatuses to support the walls of one or more blood vessels and perfuse blood through the one or more blood vessels. The stent device allows perfusion through one or more vessels. The stent device includes a tubular member. The tubular member has a single body that includes a main body lumen, a bypass lumen and one or more branch lumens. The tubular member is configured to be inserted into the aorta. The main body lumen is configured to expand and support a vessel wall of the aorta and the one or more branch lumens are configured to connect to one or more extension grafts that extend within one or more branch vessels. The stent device includes multiple rings of stents. The multiple rings of stents are positioned within the tubular member and are configured to be expandable to expand the tubular member to support the tubular member against the vessel walls.Type: ApplicationFiled: September 10, 2021Publication date: December 30, 2021Inventors: Timothy Bertini, Ana Zavala, Haley King

Publication number: 20210267748Abstract: Stent graft devices are disclosed that include a trifurcation of a main body into three branch lumens. The devices may be used to treat thoracoabdominal aortic aneurysms. The three branch lumens may split at a common point or plane in the device. One or more of the branch lumens may further split, such as bifurcate, in order to perfuse branch vessels of the aorta.Type: ApplicationFiled: March 2, 2021Publication date: September 2, 2021Inventors: Timothy BERTINI, Haley KING, Ian BARANOWSKI

Patent number: 9173736Abstract: A flat sheet of woven material includes warp yarns and weft yarns interlaced at substantially right angles to each other. A graft material is cut from the flat sheet of woven material such that the graft material includes a graft material longitudinal axis and the warp yarns are disposed at an angle relative to the graft material longitudinal axis. The warp yarns and weft yarns are not parallel to or perpendicular to the graft material longitudinal axis. The graft material is formed into the shape of an endoluminal prosthesis, such as by rolling opposing edges towards each other and securing the opposing edges to each other. The endoluminal prosthesis thus includes warp yarns disposed at an angle relative to the prosthesis longitudinal axis.Type: GrantFiled: April 28, 2011Date of Patent: November 3, 2015Assignee: Medtronic Vascular, Inc.Inventor: Timothy Bertini
