Abstract

Valves cardiaques prothétiques, ainsi que des procédés de fabrication et d'administration de valves cardiaques prothétiques. Un exemple de valve cardiaque prothétique peut comprendre un ancrage tressé en polymère. L'ancrage tressé en polymère peut être susceptible de se déplacer entre une configuration d'administration et une configuration d'ancrage. Plusieurs feuillets valvulaires peuvent être accouplés à l'ancrage tressé en polymère. Un montant peut être accouplé à l'ancrage tressé en polymère. Une boucle peut être accouplée à l'ancrage tressé en polymère. L'ancrage tressé en polymère peut être conçu pour exercer une force radiale sur un tissu biologique cible lorsqu'il se trouve dans la configuration d'ancrage, afin de s'ancrer suffisamment dans le tissu biologique cible. Le montant peut s'engager dans la boucle lorsque l'ancrage tressé en polymère se trouve dans la configuration d'ancrage.
