Patent ID: 8911488

Claim:
A stent graft delivery device comprising: a nose cone dilator at a proximal end of the device, a resilient guide wire catheter extending from a distal end of the device to and through the nose cone dilator, a pusher catheter extending from the distal end of the device towards the proximal end, a stent graft retained on the delivery device between the distal end of the nose cone dilator and the pusher catheter, the stent graft having a graft lumen therethrough and wherein the guide wire catheter extends through the graft lumen and through the pusher catheter, a pull wire fastened at or adjacent the distal end of the nose cone dilator such that when the guide wire catheter is curved during deployment, the pull wire is fastened on the inside of the curve, said pull wire extending distally and adjacent to and outside the guide wire catheter and through the stent graft lumen and the pusher catheter towards the distal end of the device, and a wire pull mechanism at or adjacent the distal end of the device operable to pull the pull wire to induce a curve in the guide wire catheter distally of the nose cone dilator, wherein when the guide wire catheter is curved during deployment, the curve of the guide wire catheter is greater than a curve of the pull wire.
