Embolic protection filters (10) formed from composite materials exhibiting certain radiopaque and elasticity characteristics are disclosed. An embolic protection filter in accordance with an exemplary embodiment of the present invention may include a support structure (14) formed of a composite member having a first layer of relatively elastic material such as superelastic nickel-titanium alloy, and a second layer formed from a relatively dense, radiopaque material. The support structure may comprise a composite wire loop that is connected to a filter membrane (12) that collects embolic debris contained in the blood. The composite wire loop may be formed at least in part of a shape-memory material configured to self-expand to a circular shape when deployed in the body. Methods of forming the support structure are also disclosed.

L'invention concerne des filtres de protection embolique (10) formés à partir de matières composites présentant des caractéristiques d'élasticité et de radio-opacité. Selon un mode de réalisation exemplaire de cette invention, un tel filtre comprend une structure support (14) formée d'un élément composite possédant une première couche de matière relativement élastique telle qu'un alliage de titane-nickel superélastique, et une seconde couche formée à partir d'une matière radio-opaque relativement dense. La structure support peut comprendre une boucle métallique composite laquelle est reliée à une membrane du filtre (12) qui collecte les débris emboliques contenus dans le sang. La boucle métallique composite peut être formée au moins en partie d'une matière à mémoire de forme conçue de manière à s'auto-expanser en une forme circulaire lorsqu'elle est déployée dans le corps. L'invention concerne également des procédés de fabrication de la structure support susmentionnée.
