  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age greater than 18 years

  • Proximal and distal landing zones with diameter between 19 mm and 42 mm.
  • Subject must have a proximal attachment zone distal to the left common carotid and a distal attachment zone proximal to the origin of the celiac artery.
  • The length of the attachment zones will depend on the intended stent graft diameter.
  • The proximal attachment zone should be: i. 15 mm for 22 - 28 mm grafts with bare stent (20 mm for RelayPro grafts with non-bare stent). ii. 20 mm for 30 - 46 mm grafts with bare stent (25 mm for RelayPro grafts with non-bare stent).

About this study

Official title: A Prospective, Multicenter, Non-Blinded, Non-Randomized Study of the RelayPro Thoracic Stent-Graft in Subjects With Traumatic Injury of the Descending Thoracic Aorta

The purpose of this study is to investigate the safety and effectiveness of the RelayPro Thoracic Stent-Grafts in subjects with traumatic injury of the descending thoracic aorta (DTA)

Read the detailed description

This is a prospective, multicenter, non-blinded, non-randomized study of the RelayPro Thoracic Stent-Graft in subjects with traumatic injury of the DTA in subjects who are candidates for endovascular repair.The primary objective of the study is all-cause mortality at 30 days post procedure.

The secondary objectives of the trial will include descriptive analyses of procedural and post-procedural observations through 5 years of follow-up.

  13. Aortic-related death

    formation, or aortic expansion

  14. Vascular access complications

    The Time Frame for reporting is during the Treatment Visit. Data should be captured upon conclusion of the Treatment Visit. Outcome measures include successful delivery and deployment of the device, as well as withdrawal of the delivery system

    Measured: During the initial implant attempt

  15. All-cause mortality

    All causes where subject death is the result of a serious and device- or procedure related adverse effect. Unrelated and accidental deaths, for example a subject death due to injuries sustained from a gunshot wound, would not be included in the evaluation.

    Measured: 1 month, 6 months, 12 months, and annually through 5 years

Questions about this trial

What is this clinical trial studying?

A study testing Relay Pro Thoracic Stent-Graft System in people with Other Specified Injury of Thoracic Aorta, run by Bolton Medical at 16 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 31 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mortality post-procedure (time frame: 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03090230, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 May 2025; AzTrials last refreshed its copy on 7 Nov 2026.
