<p>Disclosed is a system for positioning in vivo a tubular stent graft having first and second ends at either end of a bore, the system comprising a first positioner for releasable attachment to the stent graft closer to the first than to the second end, a second positioner for releasable attachment to the stent graft closer to the first than to the second end, a flexible link for releasably attaching at least one of the first and second positioners to the stent graft, means for controlling the position of the first and second positioners, a first connector connecting the first positioner to said means for controlling, and a second connector connecting the second positioner to said means for controlling, wherein one of the first and second positioners can extend beyond said first end to provide a turning point which can be used to pull the stent graft in one direction, the other positioner pulling the stent graft in the other direction in order to provide a turning couple.</p> |
