A vascular filter is provided that includes a tubular member having proximal and distal ends, and a guidewire lumen. An expandable frame is attached to the tubular member capable of assuming collapsed and enlarged conditions, and filter material is attached to the frame, the filter material having an open proximal end when the frame assumes its enlarged condition. An apparatus for recovering a vascular filter from a blood vessel is also provided that includes a sheath and a retrieval member deployable from the sheath. The retrieval member includes a connector on its distal end for securing the tubular member, such as an expandable member within a recess for receiving the tubular member. The vascular filter may be constrained in its collapsed condition in a sheath, and the tubular member advanced over a guidewire to a location downstream of a treatment site. The vascular filter is deployed and expanded to its enlarged condition across the blood vessel, the guidewire remaining in place. A procedure is performed at the treatment site, the vascular filter capturing released emboli. The retrieval device is advanced over the guidewire, the vascular filter is secured to the retrieval member, and the vascular filter and retrieval device are withdrawn from the blood vessel.

L'invention concerne un filtre vasculaire comprenant un élément tubulaire pourvu d'extrémités proximale et distale, et une lumière de fil de guidage. Un cadre extensible fixé audit élément tubulaire est capable de prendre des positions rétractée et déployée. Un matériau de filtre est fixé audit cadre, ce matériau possédant une extrémité proximale ouverte lorsque le cadre est en position déployée. L'invention concerne également un appareil permettant de récupérer un filtre vasculaire dans un vaisseau sanguin, qui comprend une gaine et un élément d'extraction déployable à partir de ladite gaine. Cet élément d'extraction comprend un connecteur placé sur son extrémité distale afin de fixer un élément tubulaire, tel qu'un élément pouvant de déployer dans un évidement de façon à recevoir ledit élément tubulaire. Le filtre vasculaire peut être contraint en position déployée dans la gaine, et l'élément tubulaire peut avancer le long d'un fil de guidage vers un emplacement situé en aval du site de traitement. Ledit filtre vasculaire est déployé et s'étend en position déployée dans le vaisseau sanguin, le fil de guidage restant en place. On exécute une procédure au niveau du site de traitement, le filtre vasculaire capturant les emboles libérés. Le dispositif d'extraction avance le long du fil de guidage, le filtre vasculaire est fixé à l'élément d'extraction, et le filtre vasculaire et le dispositif d'extraction sont retirés du vaisseau sanguin.
