A method for deploying an endoluminal vascular prosthesis using a deployment catheter that has at least a main graft portion and a first branch graft portion. When the fuel level in a fuel tank rises to a preset first fluid level, the float moves up to shut off the first connection conduit. An actuator connected to the lever can pivot the lever and displace the cushion forward into the front position. A holding unit holds first gradient correction data which is used to decide a character of an output gradient with respect to an input gradient of the image signal. The apparatus includes a body, a die coupled to the body and defining a face having a shape corresponding to a desired brand to be formed in the foam.
