NCT04471909

Brief Summary

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.

Conditions

Outcome Measures

Primary Outcomes (2)

  • Device Technical Failure

    * Failure to accurately deliver, track and deploy all required endovascular device components at the intended implantation site and failure to retrieve the device delivery systems without the need for unplanned additional procedures * Device occlusion * Failed exclusion of primary entry tear * Additional unanticipated surgical or interventional procedure related to the device or procedure, to prevent life-threatening or permanent disabling event.

    30 Days

  • Clinical Failure

    Subjects experiencing early mortality or at least one of the following MAEs through 30-Day of Phase 1 Procedure and 30-Day of Index Procedure: Disabling stroke, permanent paralysis/paraplegia, renal failure, aortic rupture, development of new dissections in the thoracic aorta or brachiocephalic artery.

    30 Days

Study Arms (3)

Chronic Dissection (arm closed to enrollment)

EXPERIMENTAL
Device: NEXUS Aortic Stent Graft System

Penetrating Aortic Ulcer and/or Intramural Hematoma

EXPERIMENTAL
Device: NEXUS Aortic Stent Graft System

Aneurysm (arm closed to enrollment)

EXPERIMENTAL
Device: NEXUS Aortic Stent Graft System

Interventions

Arch Stent Graft, whose cranial narrow end is intended to be deployed into the Brachiocephalic artery and whose distal end is intended to be deployed into the Descending Thoracic Aorta. Ascending Stent Graft intended to be deployed in the Ascending Aorta. OPTIONAL: Descending Extension can be used in case the aortic lesion elongates further distally and out of the covered length offered by the Arch Stent Graft. Multiple Descending Extensions can be used if needed to cover the entire length of the lesion.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male and female age ≥ 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 conditions:
  • An aortic aneurysm with a maximum diameter ≥ 55 mm
  • Rapidly expanding false lumen (growth of \> 0.5 cm/6 months)
  • Compressed true lumen associated with end organ malperfusion
  • Symptomatic
  • Aneurysm with at least one of the following conditions:
  • +20 more criteria

You may not qualify if:

  • Acute dissection
  • Lesions that can be safely treated with TEVAR landing in zone 2 (with or w/o LSA vascularization)
  • Required emergent treatment, e.g., trauma, rupture
  • Acute vascular injury of the aorta due to trauma
  • Aortic rupture or unstable aneurysm
  • Received a previous stent or stent graft in the treated area (including planned landing area)
  • Required surgical or endovascular treatment of an infra-renal aneurysm at time of implantation
  • Planned major surgical or interventional procedure at time of screening, to be performed after the NEXUS™ implantation.
  • Any major surgical or interventional procedure 6 weeks before the NEXUS™ implantation, exclusive of planned procedures that are needed for the safe and effective placement of the stent graft (e.g. supra-aortic bypass).
  • Subject has had a myocardial infarction (MI) or cerebral vascular accident (CVA) within 90 days prior to the planned implantation
  • Subjects with severe aortic valvular insufficiency as determined by echocardiography
  • Mechanical valve that preclude safe delivery of NEXUS™
  • Known Connective tissue disease (e.g., Marfan's or Ehler's-Danlos syndromes)
  • Subject has an active systemic infection at the time of the procedure documented by pain, fever, drainage, positive culture
  • Pregnant
  • +16 more criteria
