There is described an endovascular prosthesis delivery device. The subject endovascular prosthesis delivery device comprises a combination of a delivery frame element and a hub insert element that are secured to one another by a first retention element. At a distal portion of the delivery frame element, there is a prosthesis attachment zone for coupling to an endovascular prosthesis. When it is desired to deploy the endovascular prosthesis, the first retention element is broken in a manner to allow relative movement between the hub insert element and the delivery frame element. A pull wire assembly is secured with respect to the hub insert element and comprises a pull wire which is coupled to the endovascular prosthesis in the prosthesis attachment zone of the delivery frame element. Once the first retention element is broken by the physician (this is done when the endovascular prosthesis is in the correct position for deployment), the physician can then retract the hub insert which has the effect of retracting pull wire from the prosthesis attachment zone of the delivery frame element. The endovascular prosthesis and the endovascular prosthesis delivery device are now detached from one another and the latter may be withdrawn from the patient.
