PROBLEM TO BE SOLVED: To facilitate determination of an optimal position of a fenestration part provided on a tube wall of a tubular treatment tool.SOLUTION: A tubular treatment tool design device 1 for designing a stent graft stored in a sheath comprises: a three-dimensional model creation part 10; a simulation part 20; and a fenestration position determination part 30. The three-dimensional model creation part 10 creates a three-dimensional model of a blood vessel in which the stent graft is detented, the simulation part 20 simulates a state in which the sheath is inserted into the three-dimensional model which is created by the three-dimensional model creation part 10. The fenestration position determination part 30 determines a position of the fenestration part disposed on a tube wall of the stent graft, based on a simulation result of the simulation part 20, and information of a shape of twisting of a blood vessel in an area where the stent graft is detented.SELECTED DRAWING: Figure 1 【課題】管状治療具の管壁に設ける開窓部の最適な位置の決定を容易化する。【解決手段】シースに収容されるステントグラフトを設計する管状治療具設計装置１は、３次元モデル生成部１０、シミュレーション部２０、および開窓位置決定部３０を備える。３次元モデル生成部１０は、ステントグラフトが留置される血管の３次元モデルを生成し、シミュレーション部２０は、３次元モデル生成部１０により生成された３次元モデルにシースを挿入した状況をシミュレーションする。開窓位置決定部３０は、シミュレーション部２０によるシミュレーション結果と、ステントグラフトが留置される領域における血管のねじれの形状についての情報と、に基づいて、ステントグラフトの管壁に設ける開窓部の位置を決定する。【選択図】図１
