CA 2603217

An implantable vessel filter having an integrated sensing capability for monitoring the condition of the vessel filter. In one variation, the vessel filter includes a plurality of legs that would themselves perform as a sensor device for detecting distention, which would indicate the presence of a clot or thrombus therein. A passive electrical circuit may be implemented on the vessel filter to receive electromagnetic energy and transmit signals indicative of the condition of the implanted vessel filter. In another variation, a miniaturized sensor is adapted for measuring the strain and/or other physical parameters of the filter legs.

L'invention concerne un filtre vasculaire implantable présentant une capacité de détection intégrée pour le contrôle de l'état du filtre vasculaire. Selon une variante, le filtre vasculaire comprend une pluralité de branches se comportant elles-mêmes comme un dispositif détecteur pour la détection de la distension, révélant ainsi la présence d'un caillot ou d'un thrombus. Un circuit électrique passif peut être utilisé sur le filtre vasculaire pour recevoir l'énergie électromagnétique et émettre des signaux indicateurs de l'état du filtre vasculaire implanté. Selon une autre variante, un détecteur miniaturisé est adapté pour mesurer la contrainte et/ou d'autres paramètres physiques des branches du filtre.
