简要总结

A multicenter, prospective, open-label, non-randomized, interventional clinical study, sponsored by Endospan Ltd. Patients will be followed-up for five years.

详细描述

The purpose of the study is to evaluate the safety and performance of the Nexus™ Aortic Arch Stent Graft System for the endovascular treatment of thoracic aortic pathologies requiring landing in the Aortic Arch (zone 0, zone 1, zone 2).

The Nexus™ Aortic Arch Stent Graft System is indicated for the endovascular treatment of thoracic aortic pathologies involving the aortic arch (such as aneurisms and dissections). The Nexus™ is intended to exclude the lesion from the blood circulation in patients diagnosed with thoracic aortic pathology and who have appropriate anatomy to accommodate the Nexus™ system in an endovascular procedure.

The primary objectives of the study are to evaluate the safety and performance of the Nexus™ Aortic Arch Aneurysm Stent Graft System.

入选标准

  • Male and female age ≥
  • Any Thoracic Aorta pathology requiring landing in the Aortic Arch (zone 0, zone 1, zone2), e.g. aneurysm, dissection, false/Pseudo aneurysm.
  • In patient with a thoracic aneurysm: dilatation of the aortic arch larger than 5.5cm in diameter, or symptomatic aneurysm of the aortic arch, or aortic diameter growth rate > 5mm per 6 months
  • Patient is considered an appropriate candidate for an elective surgery, as evaluated by Physical Status Classification System I, II or III (American Society of Anesthesiologists).
  • Femoral artery diameter as documented by CTA or MRA that allows endovascular access to the diseased site with a 20-22Fr delivery catheter.
  • Access vessels morphology suitable for endovascular repair in terms of tortuosity, calcification and angulation, documented by CTA, MRA.
  • Access vessel (femoral/iliac) diameter > 7 mm
  • Ascending Aorta landing zone length > 30 mm
  • Brachial/Axial Artery diameter > 3 mm
  • Patient understands and is voluntarily willing to participate as evidenced by personally signing the Informed Consent document, and willingness to comply with follow-up schedule

排除标准

  • Female is of childbearing potential
  • Life expectancy of less than 1 year
  • Any medical condition that, according to the investigator's decision, might expose the patient to increased risk by the investigational device or procedure.
  • Acutely ruptured or instable aneurysm or an acute vascular injury due to trauma or infected penetrating ulcers of the aorta.
  • Patient with an increased risk for aneurysm rupture during the procedure.
  • Patient whose arterial access site is not anticipated to accommodate the access of the Nexus™ Delivery System, due to size, tortuosity or hostile groins (scarring, obesity, or previous failed puncture)
  • Patients with severe atherosclerosis or intraluminal thrombus of the aorta or in the BCT
  • Patient is suffering from unstable angina or NYHA classification III and IV and/or ASA classification IV and above.
  • Patient has had a myocardial infarction (MI) or cerebral vascular accident (CVA) within 3 months prior to the planned implantation
  • Patient has a known hypersensitivity or contraindication to anticoagulants, antiplatelets, or contrast media, which is not amenable to pre-treatment.
  • Patient with a contraindication to undergo angiography
  • Patient with known sensitivities or allergies to the device materials- Nitinol and polyester
  • Clinical conditions that severely inhibit x-ray visualization of the Aorta.
  • Connective tissue disease (e.g., Marfan's or Ehler's-Danlos syndromes)
  • Patient has history of bleeding diathesis or coagulopathy that may limit the use of dual antiplatelet or anticoagulant therapy by the decision of the investigator
  • Patient has an active systemic infection at the time of the procedure documented by pain, fever, drainage, positive culture and/or leukocytosis (WBC > 11,000 mm3).
  • Patients who have the condition that threatens to infect the stent graft.
  • Acute renal failure; chronic renal failure (excluding dialysis); Creatinine > 2.00 mg/dl or > 182 umol/L
  • Patient underwent major surgery or interventional procedure in the last three months.
  • Any other medical, social, or psychological issues that in the opinion of the investigator preclude them from receiving this treatment, or the procedures and evaluations pre- and post- treatment.
  • Active participation in another clinical trial that is reasonable to conflict with the NexusTM study.
