要約
(EN)
Disclosed is an artificial valve with which position shifts and blood flow leaks can be minimized or prevented. The artificial valve has a valve body and a tubular artificial valve support body that supports the valve body, and is placed percutaneously. The artificial valve comprises: protrusions that protrude from the surface on both ends of the artificial valve support body to the outside in a radiation direction, and that have an outer peripheral surface that comes into contact with in vivo tissue; and a cusped housing part having a cusp that penetrates between the protrusions on both ends. The artificial valve, with which position shifts and blood flow leaks can be minimized or prevented, is characterized in that the protrusions are formed by swelling members.

L'invention porte sur une valve artificielle au moyen de laquelle des déplacements de position et des fuites d'écoulement sanguin peuvent être réduits au minimum ou empêchés. La valve artificielle a un corps de valve et un corps de support de valve artificielle tubulaire qui supporte le corps de valve, et est placée par voie percutanée. La valve artificielle comprend : des saillies qui font saillie de la surface sur les deux extrémités du corps de support de valve artificielle vers l'extérieur dans une direction de rayonnement, et qui ont une surface périphérique externe qui vient en contact avec un tissu in vivo ; et une partie de réception pointue ayant une pointe qui pénètre entre les saillies sur les deux extrémités. La valve artificielle, au moyen de laquelle des déplacements de position et des fuites d'écoulement sanguin peuvent être réduits au minimum ou empêchés, est caractérisée en ce que les saillies sont formées par des éléments de gonflement.
