Title
(EN) FILTER DELIVERY SYSTEM
(FR) SYSTEME D'ADMINISTRATION DE FILTRE

Abstract
(EN) A filter delivery device (2) for implanting a vessel filter (32) within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter (2) with grooves (4, 6, 8, 10, 12, 14) at the distal end lumen opening. When a vessel filter (32) with radially expanding legs (34, 36, 38, 40, 42, 44) is compressed and inserted into the distal end of the delivery catheter, the hooks (20, 22, 24, 26, 28, 30) on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod (310), with a receptacle (320) for receiving the hooks is positioned within a delivery catheter to prevent entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.
(FR) La présente invention concerne un dispositif d'administration de filtre qui sert à implanter un filtre vasculaire dans le vaisseau sanguin du corps d'un patient. Le dispositif d'administration de filtre comprend un mécanisme pour éviter aux crochets et/ou pattes du filtre vasculaire de s'entremêler lorsque le filtre vasculaire est placé dans le dispositif d'administration de filtre. Dans une variante de l'invention, le dispositif d'administration de filtre comprend une sonde d'administration présentant des encoches au niveau d'une ouverture de lumière d'extrémité distale. Lorsqu'un filtre vasculaire comprenant des pattes à expansion radiale, est comprimé et inséré dans l'extrémité distale de la sonde d'administration, les crochets situés sur l'extrémité distale des pattes, sont reçus et séparés par les encoches correspondantes de la sonde d'administration. Dans une autre variante, une tige de poussée comprenant une partie de réception destinée à recevoir les crochets, est disposée dans la sonde d'administration pour éviter l'entremêlement des crochets et/ou pattes d'un filtre placé dans la sonde d'administration.
