What this Trial Is About

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.

Eligibility Criteria

Eligible

You may qualify if you...

  • Male and female age 63; 18.
  • Proximal/ascending native or previously implanted surgical graft landing zone of appropriate length.
  • Proximal/ascending native or previously implanted surgical graft landing zone of appropriate diameter.
  • Distal/descending native landing zone of appropriate length.
  • Distal/descending native landing zone of appropriate diameter.
  • Brachiocephalic trunk native landing zone of appropriate length.
  • Brachiocephalic trunk native landing zone of appropriate diameter.
  • Appropriate take off angle between the Brachiocephalic Artery and the Aortic Arch perpendicular.
  • Appropriate aortic arch perpendicular diameter.
  • Chronic dissection with at least one of the following: aortic aneurysm 63; 55 mm, rapidly expanding false lumen, compressed true lumen with end organ malperfusion, or symptomatic.
  • Aneurysm with at least one of the following: aortic arch dilatation >5 cm for fusiform aneurysm, dilatation 1.5 times normal for ascending or descending, dilatation >2.5 cm for saccular aneurysm, symptomatic, growth rate >5 mm per 6 months, or postoperative pseudoaneurysm.
  • Penetrating aortic ulcer that is symptomatic or shows expansion.
  • Intramural hematoma that is symptomatic or shows expansion on imaging.
  • Proximal/ascending native or previously implanted surgical graft landing zone appropriate if lesion is in ascending aorta.
  • Femoral/iliac artery diameter suitable for 20 Fr. delivery catheter access.
  • Access vessel morphology suitable for endovascular repair.
  • Brachial/axial artery diameter suitable for 7 Fr. access.
  • Considered an appropriate candidate for elective surgery.
  • Considered high risk for open repair by investigator.
  • Access vessels compatible with vascular access techniques and devices.
  • Willing and able to comply with study procedures and follow-up visits.
Not Eligible

You will not qualify if you...

  • Acute dissection.
  • Lesions treatable with TEVAR landing in zone 2.
  • Required emergent treatment such as trauma or rupture.
  • Acute vascular injury of the aorta due to trauma.
  • Aortic rupture or unstable aneurysm.
  • Previous stent or stent graft in the treated or planned landing area.
  • Required treatment of an infra-renal aneurysm at implantation time.
  • Planned major surgical or interventional procedure at screening.

  • Myocardial infarction or cerebral vascular accident within 90 days prior to implantation.
  • Severe aortic valvular insufficiency.
  • Mechanical valve preventing safe device delivery.
  • Known connective tissue disease (e.g., Marfan's, Ehler's-Danlos).
  • Active systemic infection at procedure time.
  • Pregnancy.
  • Life expectancy less than 2 years.
  • Unsuitable vascular anatomy.
  • Previously implanted surgical wrap of ascending aorta.
  • Medical condition increasing risk with device or procedure.
  • Mycotic, inflammatory, or suspected infected aneurysm.
  • Hostile groins or axilla unless conduit used.
  • Severe atherosclerosis, calcification, or thrombus in aorta or brachiocephalic trunk.
  • Unstable angina or NYHA class III or IV.
  • Hypersensitivity or contraindication to anticoagulants, antiplatelets, or contrast media.
  • Contraindication to angiography.
  • Known allergies to device materials.
  • Conditions severely inhibiting x-ray visualization of aorta.
  • History of bleeding disorder limiting antiplatelet or anticoagulant therapy.
  • Acute or chronic renal failure with creatinine >2.00 mg/dl.
  • Other medical, social, or psychological issues precluding treatment or study procedures.
  • Active participation in another interfering clinical study or planning to participate before this study ends.
