Abstract

L'invention concerne des systèmes d'endoprothèse vasculaire intelligente, et des procédés d'utilisation de ceux-ci pour évaluer un écoulement de fluide à travers une endoprothèse vasculaire. Des systèmes selon divers aspects de l'invention comprennent une endoprothèse vasculaire ayant une bobine configurée comme un circuit résonnant, et un lecteur. En utilisation, une oscillation est produite dans la bobine de l'endoprothèse vasculaire en appliquant un champ radiofréquence à l'endoprothèse vasculaire. Ensuite, un paramètre associé à l'oscillation est obtenu pour évaluer un écoulement de fluide à travers l'endoprothèse vasculaire. Les systèmes et procédés peuvent être utilisés dans diverses applications, comme la détection de la survenance d'une resténose.
