Patent ID: 8740964

Claim:
An endovascular delivery device comprising a distal handle, a pusher catheter extending proximally from the handle; the pusher catheter comprising a distal end at the handle and a proximal end remote from the handle, the pusher catheter comprising a longitudinal lumen therethrough, a proximal nose cone dilator, a guide wire catheter extending from the proximal nose cone dilator to the handle, the guide wire catheter extending through the longitudinal lumen of the pusher catheter whereby that the guide wire catheter is movable longitudinally and rotationally with respect to the pusher catheter, a flexible sheath over the pusher catheter, the flexible sheath extending from a connector valve and manipulator on the pusher catheter proximally to the nose cone dilator, the flexible sheath and connector valve and manipulator being able to be withdrawn to expose a stent graft mounted onto the delivery device during deployment when the delivery device is in a selected position within the vasculature of a patient, the pusher catheter further comprising a taper whereby the pusher catheter reduces in diameter continuously along the length of the pusher catheter from the connector valve and manipulator proximally to a narrowest point just distal of the proximal end of the pusher catheter and an enlarged portion of the pusher catheter at the proximal end of the pusher catheter.
