Filter by:The ENDOBARC-S post-market clinical follow-up study is undertaken to evaluate the prevention of death related to aortic arch pathologies when treated by branch stent graft systems (Nexus stent-graft system®, Relay Branch® or Zenith arch branch graft®), with proximal landing at zone 0. The secondary objective is to evaluate the safety and clinical performance of the studied devices.
This trial is a multicenter, open-label and prospective randomized controlled study to compare 1-year outcomes of uncomplicated type B intramural hematoma (IMH) patients undergoing thoracic endovascular aortic repair (TEVAR) plus optimal medical therapy (OMT) with that of those undergoing OMT alone. The primary objective is to test the hypothesis that 1-year aortic-related adverse events are lower in TEVAR plus OMT group than that in OMT alone group. The secondary objective is to test the hypothesis that 1-year all-cause mortality, aortic-related mortality and re-intervention are lower in TEVAR plus OMT group than that in OMT alone group.
Prospective, non-randomized, multi-center clinical investigation of the NEXUS™ Aortic Arch Stent Graft System (NEXUSTM) for the treatment of thoracic aortic lesions involving the aortic arch with a proximal landing zone, native or previously implanted surgical graft, in the ascending aorta and with a brachiocephalic trunk native landing zone.
The objective of this registry is to collect information on the performance and clinical benefits of the AMDS (Ascyrus Medical Dissection Stent) to treat patients with acute "DeBakey type I dissections" and with or without so called "preoperative clinically relevant malperfusion" and/or "intramural hematomas". In a healthy aorta (the vessel that supplies blood to most of the body) the blood flows freely through the main lumen (a space inside the vessel where blood flows). The participants involved in this study have a tear that has separated the inner layer of the aorta wall and created a secondary channel (false lumen) in addition to the main channel (true lumen), and huts, the blood flows through both channels. AMDS is a stent (a metal tube helping to keep the vessel open) that is placed in the descending thoracic aorta. AMDS is a medical device commercially available in the countries in which the study is being conducted and it is used as standard of care according to its indication.
The purpose of this study is to investigate the outcome of patients with pathologies of the ascending thoracic aorta (diseases in the great blood vessel or artery that leads away from the heart) including type A aortic dissection, retrograde type A aortic dissection, intramural hematoma, penetrating ulcer or pseudoaneurysm who are suitable for endovascular (within the vessel) repair with the Medtronic Valiant PS-IDE (Physician Sponsored-Investigational Device Exemption) Stent Graft. Type A aortic dissection is a condition where blood passes through the inner lining or between the layers of the blood vessel from a tear in the aortic wall (dissection) in the ascending aorta; a retrograde Type A aortic dissection is a condition where the dissection or tear in the ascending aorta starts from the descending aorta; an intramural hematoma is a collection of clotted blood within the aortic wall; a penetrating ulcer has a plaque or clot within the wall and a pseudoaneurysm is a false aneurysm . If left untreated in any of these conditions, the aorta can enlarge and rupture causing injury or death. The plan for these patients is to repair the ascending thoracic aorta using the Medtronic Valiant PS-IDE Stent Graft with the Captivia Delivery System. The Valiant Captivia has been evaluated worldwide and used extensively in patients with type B (descending) thoracic aortic dissection. Since the dissections in the ascending aortas mirror that of the descending aorta, it is expected that this stent graft will deliver similar performance and endurance in patients with type A aortic dissection. The investigators expect to reroute the blood to the true lumen (the inner space within the blood vessel) by covering the proximal (nearest to the heart) tear with the stent graft. The stent graft is a stent frame made from Nitinol wire and covered with an expandable material made of a polyester material. This new study will determine how well the device works to treat dissections, intramural hematomas, penetrating ulcers and pseudoaneurysms in the ascending thoracic aorta.
