Stent-graft prosthesis, system and method for improved delivery of a stent-graft prosthesis

摘要

The present application discloses a stent-graft prosthesis and a method for navigating such stent-graft prosthesis e.g. to a branch vessel. A first stent-graft prosthesis may include a main body and at least one lateral side branch connected to the main body. A further stent-graft prosthesis according to examples has a body having a generally tubular wall structure, the wall structure of the further stent-graft prosthesis including an orifice element for receiving a guiding element. Preferably the wall structure has an overlap region for interconnection, e.g. to the first stent-graft prosthesis. The orifice element is then arranged at said overlap region, wherein said overlap region is preferably arranged at a proximal end region of said body. The guiding element preferably is a textile thread or suture thread, optionally with a radiopaque marker, such as a fiducial marker and/or a radiopaque elongate marker extending at least along a portion of a length of said guiding element.
