  Purpose

To assess the safety and efficacy of the GORE Conformable TAG® Thoracic Endoprosthesis in the primary treatment of aneurysm of the descending thoracic aorta (DTA)

> Primary Hypothesis: The proportion of subjects free from a major device event through 1 month post-treatment will not be significantly less than 0.95, which represents the proportion observed in previous clinical studies with the GORE TAG® Thoracic Endoprosthesis


Condition Intervention
Aneurysm Device: GORE CTAG Device

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Evaluation of the GORE Conformable TAG® Thoracic Endoprosthesis for the Primary Treatment of Aneurysm of the Descending Thoracic Aortic

Primary Outcome Measures:
  • The Number of Subjects Free From a Major Device Event Through 1 Month Post-treatment [ Time Frame: Treatment through 1 month post treatment ]

Secondary Outcome Measures:
  • The Number of Subjects Experiencing a Serious Adverse Event Through One Month Post Treatment. [ Time Frame: Treatment through 1 month post procedure ]
  • Procedure Time (Minutes) [ Time Frame: Initial Device Implant Procedure During Index Hospitalization ]
    Total time in minutes required for surgical device implantation.

  • Operative Blood Loss (mL) [ Time Frame: Initial Device Implant Procedure During Index Hospitalization ]
    Blood loss in mL during initial device implantation procedure

  • Days of Convalescence Stay in an Intensive Care Unit [ Time Frame: During the Index Hospitalization ]
    Convalescence stay (days) in an Intensive Care Unit during the initial hospitalization for the device implantation

  • Total Length of Hospital Stay (Days) [ Time Frame: Total Duration of the Index Hospitalization ]
    Total days of hospital stay during the initial hospitalization for implantation of device

  • Time in Days to Return to Normal Daily Activities [ Time Frame: Average time within one month window ]
    This is the self reported time (in days) that the subject returned to pre-operative activities and is not a time to event analysis.

  • Procedural Survival [ Time Frame: Initial Device Implant Procedure During Index Hospitalization ]
    Subjects who survived the index procedure

  • Intensive Care Unit (ICU) Stay [ Time Frame: Initial Device Implant Index Hospitalization ]
    Subjects admitted to ICU during index hospitalization
