Abstract:
1. Device for treating a duct through which blood flows, the device comprising: at least one tubular endoprosthesis of longitudinal axis X-X′, which can extend radially between a contracted state and a dilated state, the endoprosthesis defining an internal duct through which blood flows; a prop of longitudinal axis Y-Y′ defining at least one proximal retention opening and at least one distal retention opening; a wire-like distal tie and a wire-like proximal tie, engaged respectively in the distal retention opening and in the proximal retention opening, each tie forming a retaining loop encircling the endoprosthesis, each retaining loop being extendible between a configuration in which the endoprosthesis is kept in its contracted state against the prop, and a configuration in which the endoprosthesis is released and in which the endoprosthesis is substantially in its dilated state, wherein, when each retaining loop is in its release configuration, the longitudinal axis X-X′ of the endoprosthesis is inclined with respect to the axis Y-Y′ of the prop when no external stresses are applied, the lonfitudinal axis X-X′ of the endoprosthesis intersecting the axis of the prop in the internal duct.
