To provide a percutaneous valve device and system which improves sealing between an anchor and a native anatomy.SOLUTION: The anchor includes a space-occupying material, such as a hydrogel, on an external surface, where the space-occupying material swells when exposed to an aqueous environment, filling gaps between the anchor and the native anatomy, and thereby serves as a valve seal.SELECTED DRAWING: None【課題】固定具と生来の組織との間の密閉を改良する経皮弁装置およびシステムを提供する。【解決手段】固定具は外表面にヒドロゲル等の空間占拠材料を含み、空間占拠材料は、水性の環境に晒されると膨張し、固定具と生来の組織との間の隙間を塞ぐことで、弁シールとして作用する。【選択図】なし
