The sutento carrier system which conveys sutento to the target territory of body lumen being sutento which it is related to the catheter and the said catheter, the 1st territory and being the balloon which it is related to sutento and the said catheter which possess the 2nd territory, balloon, and said sutento which possess the 2nd balloon section which it is related to the 1st balloon section which it is related to the catheter which it adjoins to the 1st territory of said sutento and the catheter which it adjoins to the 2nd territory of said sutento being the sheath around said balloon, has the sheath which in order to convey to the target territory of body lumen maintains said sutento in not yet development structure. The said sheath has the structure which cracks by 1st pressure, the 1st sheath territory which makes that the said 1st territory of said sutento becomes development structure with that possible, being the 2nd sheath territory which possesses the structure which cracks by 2nd pressure, the said 2nd pressure is higher than the said 1st pressure the said 1st pressure the crack of the 2nd territory of the said sheath is generated, insufficient, the 2nd sheath territory, and the said 1st sheath territory which make that the said 2nd territory of said sutento becomes development structure with that, possibleWith being divided stop structure between the said 2nd sheath territory, it is possible to have the divided stop structure of the structure which prevents the fact that from the said 1st sheath territory the crack is spread to the said 2nd sheath territory in the said 1st pressure.身体内腔の目標領域にステントを搬送するステント搬送システムは、カテーテル、該カテーテルに関連するステントであって、第1領域と第2領域を有するステント、該カテーテルに関連するバルーンであって、該ステントの第1領域に隣接したカテーテルに関連する第1バルーン部と該ステントの第2領域に隣接したカテーテルに関連する第2バルーン部を有するバルーン、及び該ステントと該バルーンの周りのシースであって、身体内腔の目標領域に搬送するために該ステントを未展開構造に維持するシースを備える。該シースは、第1圧力で割れる構造を有し、それによって該ステントの該第1領域が展開構造となるのを可能にする第1シース領域、第2圧力で割れる構造を有する第2シース領域であって、該第2圧力は該第1圧力よりも高く、該第1圧力は該シースの第2領域の割れを発生させるには不十分であり、それによって、
