Double-Branching Ascending Aortic Stent-Graft System
Summary
Endospan Ltd. published patent application US20260090874A1 for a double-branching ascending aortic stent-graft system featuring an internal support channel within a main fluid flow guide. The system allows transition between collapsed and expanded states with an elongate member passing through proximal and distal openings. The invention aims to improve treatment of aortic conditions through enhanced deployment flexibility.
What changed
Endospan Ltd. filed patent application US20260090874A1 describing a main stent-graft system with an internal support channel (120) disposed within a tubular main fluid flow guide. The internal support channel transitions from a collapsed state (where distal opening faces radially inward) to an expanded state (where opening faces distally within the main fluid flow guide). An elongate member (160A, 160B) is removably positioned passing sequentially through the proximal main-fluid-flow guide opening, longitudinal portion of the main fluid flow lumen, distal channel opening, and lateral opening to outside the lumen. CPC classifications include A61F 2/07, A61F 2/954, A61F 2/966, and related subclasses.
Medical device manufacturers developing aortic stent grafts or related endovascular devices should review this patent application for potential freedom-to-operate implications or licensing considerations. Companies engaged in aortic aneurysm or dissection treatment should assess whether their existing or planned products may fall within the scope of these claims. No immediate compliance actions are required as this is a patent publication rather than an enforceable regulatory requirement.

Abstract
A main stent-graft (22) is provided that includes an internal support channel (120) disposed within a generally tubular main fluid flow guide (28). When the internal support channel (120) is in a collapsed state, a distal channel-fluid-flow guide end opening (127B) of a channel fluid flow guide (128) faces radially inward. When the internal support channel (120) is in an expanded state and the main stent-graft (22) is in a radially-expanded deployment state, the distal channel-fluid-flow guide end opening (127B) faces at least partially distally within the main fluid flow guide (28). An elongate member (160A, 160B) is removably positioned passing sequentially through (a) a proximal main-fluid-flow guide end opening (27A), (b) a longitudinal portion (142) of a main fluid flow lumen (29) of the main-stent-graft fluid flow guide (28), (c) the distal channel-fluid-flow guide end opening (127B), and (d) a main-fluid-flow guide lateral opening (30) to outside the main fluid flow lumen (29). Other embodiments are also described.
