Publication number: 20220304805Abstract: A method of preventing paravalvular leakage includes concurrent delivery of a heart valve prosthesis and an annular sealing component. During delivery, the sealing component is moved from a first position to a second position of the heart valve prosthesis which is longitudinally spaced apart from the first position of the heart valve prosthesis. The sealing component is secured around the heart valve prosthesis at the second position by a contoured outer surface of the heart valve prosthesis. The sealing component may be a flexible ring or may be a cylindrical flexible sleeve having a plurality of ribs longitudinally extending over the cylindrical sleeve. The ribs operate to deploy the sealing component such that at least a portion of the cylindrical sleeve buckles outwardly away from the outer surface of the heart valve prosthesis.Type: ApplicationFiled: June 16, 2022Publication date: September 29, 2022Inventors: Cynthia Clague, Scott Mosher, Marian Creaven, Declan Costello, Gavin Kenny, Michael Krivoruchko, Adam Shipley, Mark Torianni, Kshitija Garde, Eric Richardson

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: 20220211484Abstract: A stent-graft prosthesis for implantation within a body vessel includes a graft material, a frame, and a channel. The graft material includes a proximal end, a distal end, and a graft lumen extending between the proximal and distal ends. The frame is coupled to the graft material. The channel is configured to relieve pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel. The channel permits blood to flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration in the body vessel. The channel may be a plurality of channels.Type: ApplicationFiled: March 24, 2022Publication date: July 7, 2022Inventors: Jeffery Argentine, Mitchell Springer, Adam Shipley, Mark Stiger

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

Patent number: 10973663Abstract: Distal tips for use with delivery catheters are disclosed that are configured to maintain complete engagement between the distal tip and a distal opening of a sheath component of the delivery catheter so as to prevent separation therebetween and/or to prevent fish-mouthing of a distal leading edge of the sheath component during in vivo use. Distal tips so configured realize one or more of the objectives of safer tracking of the delivery catheter through the vasculature, safe crossing of the delivery catheter through structural components of the vasculature and heart, such as through native valves, and safe removal of the delivery catheter post deployment.Type: GrantFiled: August 2, 2016Date of Patent: April 13, 2021Assignee: MEDTRONIC, INC.Inventors: Susheel Deshmukh, Siyan Som, Adam Shipley, Matthew Spurchise, Stephen Peter, Shishira Nagesh
