Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to evaluate the Thoraflex Hybrid device alone and in combination with the RelayPro NBS stent-graft in the treatment of aortic disease affecting the aortic arch and descending aorta with or without involvement of the ascending aorta.

Patients who undergo treatment with the Thoraflex Hybrid device with or without extension with a RelayPro NBS stent-graft will be eligible for enrolment and study activities and follow-up regime will follow standard care at each participating site.

Participant involvement in the study will last for a total of 10 years from the point at which the Thoraflex Hybrid device is placed.

Thoraflex Hybrid

Thoraflex Hybrid is designed for the open surgical repair of aneurysms and/or dissections in the aortic arch and descending aorta with or without involvement of the ascending aorta. There are two types of Thoraflex Hybrid implants, namely the Plexus 4 and the Ante-Flo versions. Each patient receives one Thoraflex Hybrid device (either the Plexus 4 or Ante-Flo).

Intervention Type DEVICE

RelayPro NBS

The RelayPro NBS Thoracic Stent-Graft System is an endovascular device intended for treatment of thoracic aortic pathologies such as aneurysms, pseudoaneurysms, dissections, penetrating ulcers and intramural hematoma.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Patient is aged 18 years or older on date of consent. Patient is willing and able to comply with all study procedures and visits. Patient or their next of kin (NOK)/legally designated representative (LDR) has given written informed consent to participate in the study.

Patient will undergo treatment with a Thoraflex Hybrid device. If a patient requires an extension procedure due to the extent of aortic disease, a RelayPro NBS Stent-graft should be placed inside the distal end of the previously placed Thoraflex Hybrid device via a retrograde approach. This may be part of the same or a two-stage procedure.

Exclusion Criteria

* Patient has any medical, social, or psychological problems that in the opinion of the investigator preclude them from receiving this treatment and the procedures and evaluations pre and post procedure.
