A plier tool for crimping electrical connectors to wires includes two plier handles that are pivotally connected together by a pivotal coupling that allows for rotation of the handles, towards and away from one another. A stent graft having a first and second end is retained upon the introducer, the stent graft defining a fenestration disposed through a wall of the stent graft between the first and second end. If the controller determines that the type of operational logic is negative, the controller applies the keyboard operational voltage to the front panel keyboard.
