摘要：
A delivery system for a branched stent graft comprises a double-layer sheath (3, 13) containing the stent graft and a towing and releasing mechanism which tows and releases the stent graft from the double-layer sheath (3, 13). After being bound, a stent main body (8) and a stent branch (11) of the stent graft are movably and entirely positioned within the double-layer sheath (3, 13). The stent main body (8) is connected with a control guiding assembly and is towed and released by the control guiding assembly. The stent branch (11) is towed by a branch guiding assembly and is connected with the control guiding assembly, so as to be released by the control guiding assembly.
