A Delivery system including an elongate tubular member (12) that has first (30) and second (32) wall portions with different acoustic impedences. An intraluminal medical device (26) is disposed on a mounting region (24) of a dilator (40) and within the elongate tubular member (12). One of the wall portions of the elongate tubular member (12) is positioned substantially adjacent a functional mechanism of the intraluminal medical device (26). This positioning facilitates placement of the intraluminal medical device within a body vessel in a particular orientation by observing the differential reflection of ultrasonic waves caused by the different acoustic impedences of the first and second wall portions of the elongate tubular member. Rotatation of the delivery system following and/or during such an observation can be employed to achieve a desired orientation of the intraluminal medical device within the body vessel.
La présente invention se rapporte à un système de distribution, qui comprend un élément tubulaire allongé (12) possédant des première (30) et seconde (32) parties parois présentant des impédances acoustiques différentes. Un dispositif médical intraluminal (26) est disposé sur une zone de montage (24) d'un dilatateur (40) et à l'intérieur dudit élément tubulaire allongé (12). L'une des parties parois de l'élément tubulaire allongé (12) est placée dans une position sensiblement adjacente à un mécanisme fonctionnel du dispositif médical intraluminal (26). Ce positionnement facilite le placement du dispositif médical intraluminal dans un vaisseau corporel selon une orientation particulière, par l'observation de la réflexion différentielle d'ondes ultrasonores causée par les impédances acoustiques différentes des première et seconde parties parois de l'élément tubulaire allongé. Il est possible de faire décrire une rotation au système de distribution après et/ou pendant une telle observation, afin que l'on obtienne une orientation désirée du dispositif médical intraluminal dans le vaisseau corporel.
