About this study
Official title: INNER-B - A Post-market Clinical Follow-up Study in Patients With Thoracoabdominal Aortic Aneurysms Treated With E-nside TAAA Multibranch Stent Graft System
The INNER-B post-market clinical follow-up study is undertaken to evaluate the prevention of death related to a thoracoabdominal aneurysm when treated by the E-nside TAAA Multibranch Stent Graft System.
The secondary objective is to evaluate the safety and clinical performance of the device.
Read the detailed description
In this study patients will be observed, who receive an E-nside TAAA Multibranch Stent Graft System for the endovascular treatment of a degenerative, atherosclerotic thoracoabdominal aortic aneurysm. The E-nside TAAA Multibranch Stent Graft will be implanted at the discretion of the treating physician.
Participating physicians will be asked to provide their observations collected during routine care for patients he/she had decided to treat with the E-nside TAAA Multibranch Stent Graft System. Informed consent of the patients to allow the use of their clinical records for the purpose of this observational study will be obtained before data are being collected.
The period of data collection will be approximately 60 months from the index procedure for each patient. Source document verification will be performed on 100% of patients; data from all visits will be reviewed and verified against existing source documents. Complete DICOM image files of the CT scans will be sent to the CoreLab for independent evaluation.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The INNER-B post-market clinical follow-up study is undertaken to evaluate the prevention of death related to a thoracoabdominal aneurysm when treated by the E-nside TAAA Multibranch Stent Graft System.
The secondary objective is to evaluate the safety and clinical performance of the device.
Detailed description
In this study patients will be observed, who receive an E-nside TAAA Multibranch Stent Graft System for the endovascular treatment of a degenerative, atherosclerotic thoracoabdominal aortic aneurysm. The E-nside TAAA Multibranch Stent Graft will be implanted at the discretion of the treating physician.
Participating physicians will be asked to provide their observations collected during routine care for patients he/she had decided to treat with the E-nside TAAA Multibranch Stent Graft System. Informed consent of the patients to allow the use of their clinical records for the purpose of this observational study will be obtained before data are being collected.
The period of data collection will be approximately 60 months from the index procedure for each patient. Source document verification will be performed on 100% of patients; data from all visits will be reviewed and verified against existing source documents. Complete DICOM image files of the CT scans will be sent to the CoreLab for independent evaluation.

Questions about this trial
What is this clinical trial studying?
An observational study of Vascular Aneurysm, run by JOTEC GmbH at 1 site in Germany.
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 9 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 17 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. 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 (time frame: 30-day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 17 Feb 2026; AzTrials last refreshed its copy on 6 Nov 2026.
