PROBLEM TO BE SOLVED: To provide an artificial valve with which position shifts and blood flow leaks can be suppressed or prevented.SOLUTION: An artificial valve includes a valve body and a tubular artificial valve support body for supporting the valve body, and is placed percutaneously. The artificial valve includes: protrusions which have an outer peripheral surface coming into contact with in vivo tissue and protrudes from the surface on both ends of the artificial valve support body to the outside in a radiation direction and a cusp housing part which allows a cusp to penetrate between the protrusions on both ends. The artificial valve can suppress or prevent position shifts and blood flow leaks.COPYRIGHT: (C)2013,JPO&INPIT【課題】位置ずれや血流のリークを抑制・防止することが可能な人工弁を提供する。【解決手段】本発明は、弁体および前記弁体を支持する管状の人工弁支持体を有し、経皮的に留置する人工弁において、生体内組織と接触する外周面を有し、かつ前記人工弁支持体の両端部の表面から放射方向外方に突出する突出部と、前記両端部の突出部の間に弁葉が入り込む弁葉収容部と、が形成されることを特徴とする位置ずれや血流のリークを抑制・防止することが可能な人工弁である。【選択図】図2
