Introducer for deploying a stent graft in a curved lumen

摘要

An introducer (10) includes release wires (42') that constrain at least one stent (4') whilst the remainder of a stent graft (18) is expanded during deployment. By allowing the constrained stent (4') to expand after an adjacent stent (4), the constrained stent (4') overlaps with the interior of the adjacent stent (4) where the stent graft (18) is deployed within a curved body lumen (70).
