An intravascular imaging guidewire (10) which can accomplish longitudinal translation of an imaging plane allowing imaging of an axial length of a region of interest without moving the guidewire. The imaging guidewire (10) comprises a body in the form of a flexible elongate tubular member. An elongate flexible imaging core is slidably received within the body. The imaging core includes a shaft having an imaging device mounted on its distal end. The body and the imaging core are cooperatively constructed to enable axial translation of the imaging core and imaging device relative to the body. The body has a transparent distal portion extending an axial length over which axially translatable imaging may be performed. The imaging guidewire (10) has a maximum diameter over its entire length sized to be received within a guidewire lumen of an intrasvascular catheter.
L'invention concerne un fil-guide d'imagerie intravasculaire (10) permettant la translation longitudinale d'un plan d'imagerie pour l'imagerie sur une longueur axiale de la région visée, sans déplacer le fil-guide. Le fil-guide (10) en question comprend un corps flexible de forme tubulaire et allongée. Un élément central d'imagerie flexible, de forme tubulaire et allongée, monté coulissant dans le corps, comprend un arbre sur l'extrémité distale duquel est monté un dispositif d'imagerie. Le corps et l'élément central d'imagerie coopèrent pour permettre la translation axiale de l'élément et du dispositif d'imagerie par rapport au corps. Le corps a une partie distale transparente qui s'étend sur une longueur axiale le long de laquelle il est possible d'effectuer une imagerie à translation axiale. Le fil-guide (10) a un diamètre maximum sur toute sa longueur pour être reçu dans la lumière du fil-guide d'un cathéter intravasculaire.
