spatial analyst - Saving raster dataset using ArcPy?

I'm trying to save filled raster object to geo database by my specified filename.

import arcpy
from arcpy import env
from arcpy.sa import *


env.workspace = r"C:\GIS Data\Cameron_Run\Topo_NED\Projected"

# Set local variables
surfaceRaster = "raw_10m_dem"

# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")

# Execute FlowDirection

fillRaster = Fill(surfaceRaster)
arcpy.RasterToGeodatabase_conversion(fillRaster, r"C:\GIS Data\Cameron_Run\Topo_NED
\Projected\fillRasterGDB.gdb")

But this code is saving raster file by its own specified name, for this case Fill_raw_10m1 is the default name of saved raster file.

Is there any way so that I can specify the name of saved raster file?
