The purpose of this study is to evaluate the safety and efficacy of endovascular repair, using the Thoracic EXCLUDER Endoprosthesis, when used in the treatment of descending thoracic aortic disease as indicated by radiological testing at time of discharge, and 1, 6, 12 months and annually following implantation, and to determine the proportion of patients who experience adverse events during and after the implantation procedure, including disease-specific and overall mortality rates.

Condition Intervention
Descending Thoracic Aortic Disease
Device: Thoracic EXCLUDER Endoprosthesis

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Clinical Study Evaluating Use of the Thoracic EXCLUDER Endoprosthesis in the Treatment of Descending Thoracic Aortic Diseases

Further study details as provided by Arizona Heart Institute:

Primary Outcome Measures:
  • Technical success [ Time Frame: following procedure ] [ Designated as safety issue: Yes ]
    Successful completion of the treatment at the initial time of the procedure defined by successful access to the arterial system, deployment, placement and patency of the Thoracic TAG Endoprosthesis at time of procedure.

  • Treatment Success [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
    Initial technical success and exclusion of the appropriate portion of the descending thoracic aortic disease from the blood circulation, defined as the absence of aneurysm enlargement (if aneurysm present) and avoidance of rupture, without major complications within 30 days of the procedure.

  • Clinical Success [ Time Frame: through 12 months ] [ Designated as safety issue: Yes ]
    Treatment success followed by patency of the graft, and continued exclusion of the appropriate portion of the descending thoracic aortic disease from the blood circulation, without reintervention, rupture, and any major complications through twelve months.

Estimated Enrollment: 332
Study Start Date: February 2000
Estimated Study Completion Date: June 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Thoracic EXCLUDER Endoprosthesis
    Stent-graft endoprosthesis is inserted by Delivery System via a surgical cutdown (e.g., external iliac artery, femoral artery, common iliac artery conduit, etc.) approach. The insertion method depends on each patient's anatomy and is determined by the Clinical Investigator.
  Show Detailed Description


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Thoracic aortic disease deemed to warrant exclusion in order to prevent rupture or extension including dissection and transections.
  • Anatomy meets Thoracic EXCLUDER Endoprosthesis specification criteria.
  • Minimum 2 cm non-aneurysmal segment proximal and distal to the aneurysm.

    • < 60 angle in the aortic arch may require additional length of non- aneurysmal segment if the arch is included in the treatment segment.
  • The patient is of a "high risk" status for surgical repair. The patient is characterized by the presence of co-morbid factors and/or thoracic aortic pathology that place the patient in a category of prohibitive risk for open repair, and, without intervention, and adverse event could be anticipated within days or weeks. The patient has an ASA score of IV or V.
  • Ability to comply with protocol requirements including follow-up.
  • Signed Informed Consent Form.

Exclusion Criteria:

  • > 4 mm aortic taper and inability to use devices of different diameters, to compensate for the taper, in the treatment area of the aorta.
  • Significant thrombus at the proximal or distal implantation sites.
  • Planned occlusion of the left carotid or celiac arteries, unless supplemental conduit provided.
  • Myocardial infarction within six weeks.
  • Degenerative connective tissue disease, e.g. Marfan's or Ehler Danlos Syndrome, unless the proximal and distal implantation sites of the Thoracic EXCLUDER Endoprosthesis are located within previously placed surgical grafts.
  • Female of child bearing potential with positive pregnancy test.
