Patent ID: 7976575

Claim:
A stent graft delivery arrangement comprising: a delivery device comprising a proximal end to be deployed into a patient in use and a distal end to remain outside the patient in use; a stent graft releasably retained onto the delivery device towards the proximal end thereof, the stent graft comprising a tubular body of a biocompatible graft material and a plurality of self expanding stents therealong and the stent graft comprising a proximal end and a distal end; a curve forming arrangement on the stent graft arranged in use to curve a portion of the stent graft by the proximal end thereof; a pulling arrangement extending along the delivery device and releasably engaging the curve forming arrangement on the stent graft, whereby pulling on the pulling arrangement causes the curve forming arrangement on the stent graft to curve a portion of the stent graft by the proximal end thereof and the pulling arrangement can be released leaving the curve forming apparatus in place on the stent graft; wherein the curve forming arrangement comprises a suture thread engaged to the stent graft or a stent of the stent graft at a first position spaced from the proximal end of the stent graft, extending in at least two directions to at least two second positions spaced circumferentially apart and adjacent to the proximal end of stent graft, at a third position releasably engaged to the pulling arrangement and a gripping arrangement engaging the suture thread between the second position and the third position to prevent re-extension of the suture thread after retraction thereof.
