Patent number: 9839542Abstract: An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, and forms a lumen therethrough. The mobile external coupling includes a graft material, extends outwardly from the tubular body, and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top that is in flow communication with the body lumen. An annular support wireform is coupled to the mobile external coupling, and is formed into a sinusoidal configuration having a plurality of opposing first crowns and second crowns, the first crowns of the support wireform extending around of the top of the mobile external coupling. The coupling graft material extending between the second crowns of the support wireform and the tubular body is unsupported.Type: GrantFiled: April 19, 2011Date of Patent: December 12, 2017Assignee: Medtronic Ardian Luxembourg S.a.r.l.Inventors: Walter Bruszewski, Malhar Desai

Patent number: 9549830Abstract: A method of deploying an eversible branch stent-graft includes deploying the eversible branch stent-graft into a main vessel such that a collateral opening in a main stent-graft of the eversible branch stent-graft is aligned with an ostium of a branch vessel emanating from the main vessel. A branch stent ring suture threaded though outer exposed crowns of an outer stent ring of the branch stent-graft is grasped and pulled through the collateral opening to evert the branch stent-graft into the branch vessel as a branch anchor suture is removed to release a protruding end of a branch stent-graft from a proximal end of the main stent-graft.Type: GrantFiled: February 5, 2015Date of Patent: January 24, 2017Assignee: Medtronic Vascular, Inc.Inventors: Walter Bruszewski, Masoumeh Mafi, Shyam Nagasrinivasa, Maria Acosta de Acevedo

Patent number: 9393136Abstract: A variable zone high metal to vessel ratio stent includes a proximal high metal to vessel ratio zone, a central low metal to vessel ratio zone, and a distal high metal to vessel ratio zone. The proximal high metal to vessel ratio zone is deployed with fixation and sealing to healthy tissue of a main vessel superior to branch vessels and an aneurysm. The central low metal to vessel ratio zone is deployed directly on ostai of the branch vessels. However, as the central low metal to vessel ratio zone is highly permeable, blood flows from the main vessel through the central low metal to vessel ratio zone and into branch vessels.Type: GrantFiled: March 27, 2012Date of Patent: July 19, 2016Assignee: Medtronic Vascular, Inc.Inventors: Keith Perkins, Samuel Robaina, Jeffery Argentine, Walter Bruszewski, Andrew Kiehl

Patent number: 9005270Abstract: A method includes covering ostai of branch vessels emanating from a main vessel and an aneurysm with a high metal to vessel ratio stent. A metal to vessel ratio of the high metal to vessel ratio stent is sufficiently high to encourage tissue ingrowth around the high metal to vessel ratio stent yet is sufficiently low to ensure perfusion of the branch vessels through the high metal to vessel ratio stent. The ingrowth of tissue provides secure fixation and sealing of the high metal to vessel ratio stent to the main vessel and remodels and essentially eliminates the aneurysm. Further, as the entire high metal to vessel ratio stent is permeably, the high metal to vessel ratio stent is deployed without having to rotationally position the high metal to vessel ratio stent.Type: GrantFiled: March 27, 2012Date of Patent: April 14, 2015Assignee: Medtronic Vascular, Inc.Inventors: Keith Perkins, Samuel Robaina, Jeffery Argentine, Walter Bruszewski, Andrew Kiehl
