A push catheter for placement of a biliary stent. The push catheter includes an elongate shaft (56) extending from a hub assembly. The elongate shaft includes a distal segment (53) having a lumen (63) extending therethrough, and a proximal segment (51) having a plurality of lumens (61, 62) extending therethrough. The proximal segment is secured to the distal segment, such that the plurality of lumens of the proximal segment are in association with the lumen of the distal segment. The distal end of the proximal segment may be formed at an oblique angle to the longitudinal axis of the elongate shaft. Additionally, the elongate shaft may include a side port (58) providing access to one or more of the plurality of lumens of the proximal segment.

L'invention concerne un cathéter de poussée destiné à positionner un système de tuteur biliaire. Le cathéter de poussée comprend un arbre allongé s'étendant à partir d'un ensemble de moyeu. L'arbre allongé comprend un segment distal ayant une lumière s'étendant à travers celui-ci, et un segment proximal ayant une pluralité de lumières s'étendant à travers celui-ci. Le segment proximal est fixé sur le segment distal, de sorte que la pluralité de lumières du segment proximal est associée à la lumière du segment distal. L'extrémité distale du segment proximal peut être formée selon un angle oblique par rapport à l'axe longitudinal de l'arbre allongé. De plus, l'arbre allongé peut comprendre un orifice latéral donnant accès à une ou plusieurs de la pluralité de lumières du segment proximal.
