Multi-lumen stent graft

A multi-lumen stent graft, comprising a tubular main body stent graft and a tubular connection stent graft, wherein

• the main body stent graft comprises a tubular main body stent;
• the main body stent comprises a tubular main body covering and a main body support frame fixed on a wall of the main body covering;
• and a main lumen and at least one sub lumen are separated axially by a separation covering within the main body stent;
• in a released state, a proximal end of the connection stent graft and the main lumen at a distal end of the tubular main body stent graft are fitted and connected together;
• wherein a transverse covering is provided at least between the distal end of the main body covering and the separation covering, and the main body covering and the separation covering are connected together by the transverse covering, wherein
• the transverse covering comprises at least one planar structure and at least one inclined surface structure, and the planar structure and the inclined surface structure are integral or are connected together.
