The artery which it throbs, like the peristalsis organ or the sphincter nearby cavity, the lining of cartridge condition for insertion to in the coelom which possesses the inside diameter which fluctuates. As for this lining, although inside diameter of the cavity fluctuates, therefore, continuing the lining in form of the cavity, in order to be able to agree, it possesses the resistance of the diameter direction which is smaller than power of the diameter direction which is added to the lining by the cavity.拍動する動脈、蠕動器官、又は括約筋近くの腔のように、変動する内径を有する体腔中への挿入用の筒形状のライニング。このライニングは、腔の内径が変動するのに従って、ライニングを腔の形状に連続して一致させ得るように、腔によってライニングに加えられる径方向の力よりも小さい径方向の抵抗を有する。
