A deployment system for introducing stent grafts which have a side arm or into which a side arm can be deployed. For instance the stent graft can be deployed into the thoracic arch of a patient. The deployment system including an introducer (1), an auxiliary catheter (13) disposed within the introducer and an auxiliary guide wire (14) disposed within the auxiliary catheter. The auxiliary guide wire extends to adjacent the proximal end (6) of the introducer an can be extended from the proximal end of the introducer so that it can be snared from a side branch artery (56) to assist with deployment of a side arm (23) of the stent graft into the side artery or for the deployment of a side arm stent graft into the stent graft.
A deployment system for a stent graft to be deployed into an internal lumen of a patient, the deployment system comprising in combination an introducer and a stent graft retained on the introducer, a catheter associated with the introducer extending through at least a portion of the stent graft, the at least a portion of the stent graft comprising diameter reducing ties with an associated trigger wire and trigger wire release mechanism, the diameter reducing ties being used to hold the least a portion of the stent graft in a diameter reduced condition against the catheter associated with the introducer, the catheter associated with the introducer comprising a bulge where it passes through the least a portion of the stent graft with the diameter reducing ties either side of the bulge whereby the diameter reducing ties and bulge effectively grip the catheter associated with the introducer and the least a portion of the stent graft such that the combination move together.
