Patent ID: 8506616

Claim:
An endoluminal stent graft deployment device in combination with a stent graft retained thereon, the device including a distal end to remain outside a patient in use and a proximal end to be deployed endoluminally into a patient and the stent graft releasably retained on the device towards the proximal end thereof, the device comprising an anchoring arrangement, the anchoring arrangement enabling anchoring of a portion of the stent graft, the anchoring arrangement comprising an anchor wire extending from the distal end of the device and the anchor wire being releasably retained to the portion of the stent graft by a releasable retention system, the releasable retention system including a bead on the proximal end of the anchor wire, an anchor wire release wire and a fastening arrangement to retain the anchor wire to the portion of the stent graft distally of the bead, the anchor wire release wire being engaged with the fastening arrangement to prevent release of the fastening arrangement, the anchor wire release wire extending to the distal end of the device, the bead on the anchor wire configured to engage against the fastening arrangement thereby preventing the anchor wire from being released from the portion of the stent graft until the fastening arrangement is released, whereby the anchor wire release wire can be withdrawn thereby releasing the fastening arrangement and thereby the anchor wire, wherein the fastening arrangement comprises a suture fastened through the portion of the stent graft and around the anchor wire distal of the bead and retained by a knot which is locked by the anchor wire release wire, whereby the anchor wire release wire can be withdrawn from the knot thereby releasing the suture and hence the anchor wire.
