NEXUS Aortic Arch Clinical Study to Evaluate Safety and Effectiveness (TRIOMPHE)

March 14, 2024 updated by: Endospan Ltd.

A Multi-arm, Multi-Center, Non-Randomized, Prospective, Clinical Study to Evaluate the Safety and Effectiveness of the NEXUS Aortic Arch Stent Graft System in Treating Thoracic Aortic Lesions Involving the Aortic Arch

Prospective, non-randomized, multi-center clinical investigation of the NEXUS™ Aortic Arch Stent Graft System (NEXUSTM) for the treatment of thoracic aortic lesions involving the aortic arch with a proximal landing zone, native or previously implanted surgical graft, in the ascending aorta and with a brachiocephalic trunk native landing zone.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Non-Randomized
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Chronic Dissection

Arch Stent Graft, whose cranial narrow end is intended to be deployed into the Brachiocephalic artery and whose distal end is intended to be deployed into the Descending Thoracic Aorta.

Ascending Stent Graft intended to be deployed in the Ascending Aorta.

OPTIONAL: Descending Extension can be used in case the aortic lesion elongates further distally and out of the covered length offered by the Arch Stent Graft. Multiple Descending Extensions can be used if needed to cover the entire length of the lesion.

Experimental: Aneurysm

Arch Stent Graft, whose cranial narrow end is intended to be deployed into the Brachiocephalic artery and whose distal end is intended to be deployed into the Descending Thoracic Aorta.

Ascending Stent Graft intended to be deployed in the Ascending Aorta.

OPTIONAL: Descending Extension can be used in case the aortic lesion elongates further distally and out of the covered length offered by the Arch Stent Graft. Multiple Descending Extensions can be used if needed to cover the entire length of the lesion.

Experimental: Penetrating Aortic Ulcer and/or Intramural Hematoma

Arch Stent Graft, whose cranial narrow end is intended to be deployed into the Brachiocephalic artery and whose distal end is intended to be deployed into the Descending Thoracic Aorta.

Ascending Stent Graft intended to be deployed in the Ascending Aorta.

OPTIONAL: Descending Extension can be used in case the aortic lesion elongates further distally and out of the covered length offered by the Arch Stent Graft. Multiple Descending Extensions can be used if needed to cover the entire length of the lesion.
