Abstract | A radiopaque marker that is incorporated into an implantable biocompatible device for precise imaging as the device is delivered and deployed within a body vessel. The radiopaque marker can take on a variety of forms which can be excised from a thin foil made of radiopaque metal or from an ePTFE sheet that has been coated on one or both surfaces with a radiopaque metal. The radiopaque markers, in forms such as rings, strips, disks, rectangles or spheres are encapsulated or contained within the implantable device to prevent the radiopaque metal from dissolving or escaping into the blood stream. Strategic placement of the radiopaque markers at each end of the implantable device enables the physician to fluoroscopically view its exact location prior to deployment and in subsequent follow-up examinations.
L'invention porte sur un marqueur radio-opaque incorporé à un dispositif biocompatible implantable permettant d'obtenir une image précise lorsque le dispositif est placé et déployé dans un vaisseau du corps. Lesdits marqueurs, découpées dans des feuilles mince de métal radio-opaque ou dans des feuilles de PTFE revêtues sur une ou deux faces d'un métal radio-opaque, et pouvant prendre diverses formes, telles qu'anneaux, bandes, disques, rectangles ou sphères, sont encapsulés ou inclus dans le dispositif implantable de manière à empêcher leur dissolution ou leur fuite dans le courant sanguin. Lesdits marqueurs disposés aux deux extrémités du dispositif implantable permettent au médecin de voir par fluoroscopie sa position exacte avant sa mise en place ou lors des examens de suivi subséquents. |
