A delivery system (200) for delivering a lumen stent (100). The delivery system (200) comprises a fixing anchor (270) and a fixing cap (260) which is cylindrical and has an opening at a proximal end, the fixing anchor (270) comprising a hollow insertion part (271) and an abutment part (273) connected to the insertion part (271)； parts of the side surface of the insertion part (271) are recessed towards the interior of the insertion part (271) to form a plurality of positioning grooves (2711) that extend to a proximal end surface of the insertion part (271), a separator (2713) being formed between every adjacent two positioning grooves (2711)； the abutment part (273) comprises a carrier (2731) and a plurality of first position-limiting pieces (2733) provided on a side of the carrier (2731), a distal end of each first position-limiting piece (2733) being provided to correspond to an open side of a positioning groove (2711) adjacent to the abutment part (273)； distal end surfaces of the plurality of first position-limiting pieces (2733), a distal end surface of the carrier (2731) and proximal end surfaces of the separators (2713) are coplanar. When the fixing anchor (270) and the fixing cap (260) are joined, the insertion part (271) is inserted into the fixing cap (260), and the distal end surfaces of the first position-limiting pieces (2733) abut the proximal end surface of the fixing cap (260). Further disclosed is a lumen stent system. The delivery system (200) can be smoothly and safely withdrawn out of the human body.
