A brake hub and a second gear shaft are rotatably supported by a bearing and a bearing, the bearing interposed between a projection of a support member disposed on the inner side of a recess of the brake hub and the inner peripheral surface of the recess, the bearing interposed between a support member surrounding a top end portion of the brake hub and the top end portion of the brake hub. If the number of remembered set entries for references from a second region to a first region reaches a predetermined threshold, the second region is constrained so that it will be collected at the same time as, or before, the first region. A heat source contemporaneously heats the water heating coil, the steam heating coil and the pressure vessel. The method further comprises applying electrical energy energy) to the vascular electrode array to therapeutically conduct electrical energy into a region of the targeted tissue adjacent the embolized region of the vascular network.
