Publication number: 20240082027Abstract: A distal aortic stent graft assembly including a main body having a proximal end and a distal end. The main body defines a peripheral opening. The proximal end defines a proximal opening. The distal end defines a distal opening. The proximal opening and the distal opening are configured to perfuse blood through the main body when the main body is in a deployed state. The distal aortic stent graft assembly further includes a coupling extending radially from the main body and corresponding to the opening in the main body. The coupling is configured to align with a blood vessel and perfuse blood through the coupling when the coupling is in the deployed state.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Keith PERKINS, Zachary BORGLIN, Mark STIGER, Julie BENTON, Steven CLAESSENS, Travis ROWE, Mark YOUNG

Patent number: 11850173Abstract: The techniques of this disclosure generally relate to a modular stent device that is deployed into the ascending aorta via femoral access. The modular stent device is a base or anchor component to which additional modular stent devices can be attached to exclude diseased areas of the aorta while at the same time allowing perfusion of the brachiocephalic artery, the left common carotid artery, and/or the left subclavian artery.Type: GrantFiled: June 29, 2021Date of Patent: December 26, 2023Assignee: Medtronic Vascular, Inc.Inventors: Keith Perkins, Zachary Borglin, Mark Stiger, Julie Benton, Steven Claessens, Travis Rowe, Mark Young

Patent number: 11826226Abstract: The techniques of this disclosure generally relate to a modular stent device including a main body configured to be deployed in the ascending aorta, a bypass gate configured to be deployed in the aorta, and a bifurcated contra limb. The bifurcated contra limb includes a single proximal limb that is bifurcated (split) into a first distal limb and a second distal limb. By forming the bifurcated contra limb to include a single proximal limb that is bifurcated into the distal limbs, guiding a guide wire into the relatively larger opening of bifurcated contra limb at a proximal end is simpler than guiding a guidewire into two smaller limbs extending distally from main body. Accordingly, cannulation of the bifurcated contra limb is relatively simple thus simplifying the procedure. In addition, the parallel design mimics anatomical blood vessel bifurcations to limit flow disruptions.Type: GrantFiled: July 31, 2019Date of Patent: November 28, 2023Assignee: Medtronic Vascular, Inc.Inventors: Keith Perkins, Zachary Borglin, Mark Stiger, Julie Benton, Steven Claessens, Travis Rowe, Mark Young

Patent number: 11617641Abstract: Systems and methods for building a landing zone for an endovascular procedure are described. This procedure is “hybrid” in that it involves both direct access (e.g., sternotomy or partial sternotomy) to the site for installation of the landing zone, as well as endovascular installation of a TAVR or TEVAR device (e.g., stent graft) once the landing zone is installed. The landing zone is installed by wrapping a landing band around a portion of a vessel. The landing band may be selected to be fixed at a diameter so that it inhibits any expansion of the vessel, and also supports a later-installed TAVR or TEVAR device. The TAVR or TEVAR device is then endovascularly delivered to the vessel and deployed therein. The device expands until it contacts the vessel, which is supported from the outside by the landing band, which thus constrains and supports the device from outside.Type: GrantFiled: June 22, 2021Date of Patent: April 4, 2023Assignee: Medtronic Vascular, Inc.Inventors: Keith Perkins, Mark Stiger, Steven Claessens

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
