STENT DELIVERY SYSTEM

摘要

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.
