E-nside™ Inner Branch Stent Graft System
E-nside™ is the world’s first "off-the-shelf" inner-branched stent-graft system designed for the endovascular treatment of thoracoabdominal aortic aneurysms (TAAA). It represents a revolutionary solution for urgent cases where custom-made devices are not an option, as well as elective cases fitting the anatomical criteria. The system features four pre-cannulated inner branches dedicated to the revascularization of the celiac trunk, superior mesenteric artery, and renal arteries.
Overview: E-nside™ is the world’s first "off-the-shelf" inner-branched stent-graft system designed for the endovascular treatment of thoracoabdominal aortic aneurysms (TAAA). It represents a revolutionary solution for urgent cases where custom-made devices are not an option, as well as elective cases fitting the anatomical criteria. The system features four pre-cannulated inner branches dedicated to the revascularization of the celiac trunk, superior mesenteric artery, and renal arteries.
Technological Innovations:
Inner-Branch Technology: Unlike traditional outer-branched designs, the internal orientation of the branches allows for deployment in smaller aortic diameters and reduces the profile against the vessel wall, minimizing stress on surrounding structures.
Asymmetric Proximal Stent Row: A fully covered, asymmetric proximal configuration reduces the risk of catheter or wire incarceration in bare stents during the procedure.
Pre-Cannulated Channels: The integrated pre-cannulation of the branches is intended to significantly reduce cannulation time and radiation dose by up to 30%.
Clinical Advantages & Research: The 2-year outcomes from the INBREED (ItaliaN Branched Registry of E-nside EnDograft) study (presented in 2026) confirm high technical success and low morbidity rates. The inner-branch design extends the therapeutic window to patients with renovisceral segments as small as 24 mm in diameter.
