Arm Intervention/treatment
Experimental: Acute DeBakey Type I Dissection
In eligible patients, the ascending aorta is transected and removed in a routine standard of care manner utilizing hypothermic circulatory arrest; the operator will leave at least 10 mm (1.0 cm) aortic tissue proximal to the innominate artery. AMDS is pre-loaded onto the delivery system and is delivered into the true lumen through the open distal aorta and implanted according to the instructions for use.
Device: AMDS
AMDS Implantation

Primary Outcome Measures :
  1. Primary Endpoint to Assess Incidence of Major Adverse Events [ Time Frame: Through 30 days ]

    Patients experiencing at least one of the following MAEs:

    1. All-cause mortality (ACM)
    2. New disabling stroke
    3. New onset renal failure requiring dialysis
    4. Myocardial infarction (MI)

  2. Primary Endpoint to Assess Change in Maximal True Lumen (TL) diameter [ Time Frame: At 1 year ]

    Patients with clinically meaningful (≥ 6.0 mm) true lumen expansion (at 1-Year), as defined by:

    Change in maximal true lumen (TL) diameter in the aortic arch at Zone 3 (2 cm distal to the origin of the left subclavian artery) from pre-operative computed tomography angiogram (CTA) measurements on admission to 1-year CTA measurements without need for device-related aortic reintervention.

  • Coronary malperfusion
  • In circulatory shock (i.e., systolic blood pressure <90 mmHg) at time of screening
  • In extreme hemodynamic compromise requiring cardiopulmonary resuscitation at time of screening
  • Suspicion of bowel necrosis (as determined by the implanting physician based on imaging observations, peritoneal signs, surgical exploration, elevated serum lactate levels, low pH, and/or acidosis)
  • Clinical or radiographic signs of bowel infarction or gastrointestinal hemorrhage
  • Base deficit > -10 mmol/L or -10 mEq/L

  • Previous placement of a thoracic endovascular graft
  • Interventional and/or open surgical procedures 30 days prior to the dissection repair
  • Planned major interventional and/or open surgical procedures 30 days post the dissection repair
  • Systemic infection
  • Uncontrollable anaphylaxis to iodinated contrast (patients with allergy to iodinated contrast but not anaphylaxis may be eligible with appropriate pre-medication, as deemed suitable by the Investigator)
  • Known allergy(ies) to nitinol and/or polytetrafluoroethylene
  • Inability to obtain CT angiograms for follow-up
  • Previously diagnosed with Marfan syndrome, Ehlers-Danlos syndrome, or Loeys-Dietz syndrome based on laboratory genetic testing

  • Any pathology of mycotic origin
  • Aortic fistulous communication with non-vascular structure (e.g., esophagus, bronchial)
  • Extensive thrombus or calcifications in the aortic arch, as defined by CTA
  • Excessive tortuosity precluding safe passage of the AMDS, as defined by CTA
