Abstract
A stent graft introducer (1) which includes a handle arrangement which by telescopic movement of a slide or slide portions (104, 106) into a handle portion (100) causes controlled sequential deployment of a stent graft (14). Stops (218,217, 218, 219) ensure actions are carried out in a selected order. A sheath (116) of the introducer is fixed to a slide portion such that with retraction of the slide portion the sheath is withdrawn from a stent graft retained on the introducer and at a selected position trigger wires retaining the stent graft onto the introducer are also released. Interconnections between the slides and the handle are provided to prevent relative rotation and re-extension after full retraction.
