A releasable and retrievable vascular filter system comprising a filter, a porous filter membrane attached to the filter, and an anti-migration feature for causing the filter to remain substantially stationary in the lumen of the vessel during the clinical procedure. The releasable and retrievable vascular filter system minimizes or substantially eliminates filter movement during the procedure, which may result in damage to the lumen, and/or the release of embolic particulates captured within the filter. The releasable and retrievable vascular filter system also allows for guidewire exchanges, which may be necessary for successful completion of the clinical procedure.

L'invention concerne un système de filtrage vasculaire récupérable qui comprend un filtre, une membrane poreuse attachée au filtre et une propriété anti-migration pour faire en sorte que le filtre demeure essentiellement stationnaire dans le lumen de la cuve durant une procédure clinique. Le système de filtrage vasculaire récupérable minimise ou élimine considérablement le mouvement du filtre durant la procédure, ce qui peut endommager le lumen et/ou libérer des particules emboliques retenues dans le filtre. Le système de filtrage vasculaire récupérable permet également des échanges de guide métallique, ce qui peut s'avérer nécessaire pour mener à bien la procédure clinique.
