Abstract

An endovascular introducer which has a handle assembly, a stent graft deployment device and a stent graft retained on the stent graft deployment device. The handle assembly has a first part and a second part, the second part to be moved relative to the first part. The first part has a fixed portion to be gripped and held by a user and a rotating portion to be rotated. A one way clutch arrangement transfer rotation to co-acting first screw threads so that relative longitudinal motion between the first part and the second part occurs. The deployment device has a pusher assembly and a sheath to cover the stent graft on the pusher assembly. The sheath is connected to the second part so that rotation of the rotating portion causes retraction of the sheath.
