• 1 other identifier: SSB 11-02
• Study Type: interventional
• Target: 31
• Locations: 1 country
• Sites: 6

Brief Summary

The purpose of this study is to assess the feasibility of the use of the GORE® TAG® Thoracic Branch Endoprosthesis to treat aneurysms involving the proximal Descending Thoracic Aorta (DTA)

Conditions

Aortic Aneurysm, Thoracic

Outcome Measures

Primary Outcomes (3)

• Number of Participants With Successful Study Device Access

  Access to the aneurysm and target landing zone location is obtained via conventional vascular access and endovascular techniques.

  During treatment procedure (day 0)

• Number of Participants With Successful Study Device Deployment

  Absence of deployment failure will be considered a successful deployment. Deployment failure will be considered the failure of any Branched TAG® Device component (Aortic Component, Aortic Extender, or SB Component) to be released from the delivery catheter resulting in a serious adverse event (SAE) due to mechanical failure or use error.

  During treatment procedure (day 0)

• Number of Participants With Primary Procedural Side Branch Patency as Assessed by Angiography

  The presence of forward flow through the implanted Side Branch Component into the target branch vessel.

  At conclusion of the treatment procedure (day 0)

Secondary Outcomes (2)

• Number of Participants With 1 Month Side Branch Primary Patency Assessed by an Independent Core Lab

  1 Month

• Number of Participants Without 1 Month Device Related Endoleaks Assessed by an Independent Core Lab

  1 Month

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Presence of DTA aneurysm deemed to warrant surgical repair which requires proximal graft placement in Zone 2:
• Fusiform (≥ 55 mm), or
• Fusiform (\>2 times native aortic diameter), or
• Saccular (no diameter criteria)
• Age ≥18 years at time of informed consent signature
• Subject is capable of complying with protocol requirements, including follow-up
• Informed Consent Form (ICF) is signed by Subject or legal representative
• Must have appropriate proximal aortic landing zone, defined as:
• Aortic inner diameters between 16-48 mm
• Landing zone, which must include the LSA ostium, cannot be aneurysmal, heavily calcified, or heavily thrombosed,
• Acceptable proximal landing zone outer curvature length for the required device
• Landing zone must be native aorta
• Must have appropriate distal aortic landing zone, defined as:
• Outer curvature length must be ≥2cm proximal to the celiac artery
• Aortic inner diameters between 16-48mm (diameter should be between 16-42mm if using distal TAG® Device extension)

You may not qualify if:

• Concomitant aneurysm/disease of the ascending aorta, aortic arch, or abdominal aorta requiring repair
• Previous endovascular repair of the ascending aorta
• Previous endovascular repair of the DTA with a non-Gore device
• Surgery within 30 days of treatment
• Infected aorta
• Dissection of the DTA
• Intramural hematoma of the DTA without DTA aneurysm
• Life expectancy \<2 years
• Myocardial infarction or stroke within 6 weeks prior to treatment
• Patient has a systemic infection and may be at increased risk of endovascular graft infection
• Pregnant female at time of informed consent signature
• Degenerative connective tissue disease, e.g. Marfan's or Ehler-Danlos Syndrome
• Participation in another drug or medical device study within one year of study enrollment
• Known history of drug abuse within one year of treatment
• Significant thrombus or atheroma in the aortic arch
