It is the blood vessel plug technique system which is included the calculation element which calculates the capacity of the selective part of the target blood vessel on the basis of the mapping element and the size of the blood vessel which measure the size of the target blood vessel, combining with the delivery element of the plug substance which includes distal (2036) end, distal (2036) end when being actuated position, opens inside the target blood vessel, composure can point to the plug substance inside the selective part of the target blood vessel. Execution form of this invention decides the capacity of the blood vessel which supplies the blood to the target organizational lump, makes the calculation of the optimum quantity of the plug component which is supplied to this blood vessel possible.標的血管の寸法を測定するマッピング要素と、血管の寸法に基づき標的血管の選択部分の容積を計算する計算要素とを、遠位末端を含む塞栓物質の送達要素と組み合わせて含む血管塞栓術システムであり、遠位末端は作動位置にあるときに標的血管内に開口し、塞栓物質を標的血管の選択部分内に沈着させる。本発明の実施形態は、標的組織塊に血液を供給する血管の容積を決定し、この血管に供給される塞栓成分の最適量の算出を可能にする。
