The endoluminal device delivery assembly (10) and method for release and deployment of an endoluminal therapeutic device (28) at a desired location for treatment within the vasculature of a patient utilizes an elongated flexible tubular catheter (12) with a tubular distal tip (16) formed of a yieldable material mounted to the distal end (14) of the catheter (12) for releasably holding the proximal end (28) of the endoluminal device (28). The endoluminal device (28) can be dislodged from the tubular distal tip (16) by a pusher member (34) or pressurized fluid to expel the endoluminal device (28) through at the desired location for treatment within the vasculature of a patient. A flexible coil (40) can be mounted to the distal end (38) of the elongated pusher member (34) to provide for improved tracking.

L'invention concerne un ensemble d'administration (10) d'un dispositif endoluminal et un procédé de libération et de déploiement d'un dispositif thérapeutique endoluminal (28) au niveau d'un emplacement souhaité, aux fins de traitement dans le système vasculaire d'un patient, lequel met en oeuvre un cathéter tubulaire souple et allongé (12) comprenant une pointe distale tubulaire (16) qui est conçue dans un matériau élastique et montée sur l'extrémité distale (14) du cathéter (12), de manière à maintenir amovible l'extrémité proximale (28) du dispositif endoluminal (28). Celui-ci (28) peut être débloqué de la pointe distale tubulaire (16) au moyen d'un élément pousseur (34) ou d'un fluide sous pression, de manière à expulser le dispositif endoluminal (28) au niveau de l'emplacement souhaité, aux fins de traitement dans le système vasculaire d'un patient. Une bobine souple (40) peut être montée sur l'extrémité distale (38) de l'élément pousseur allongé (34), de manière à permettre un déplacement amélioré.
