Autodesk.Revit.DB.Parameter to Revit.Elements.Parameter

How can I wrap DB.Parameter to Revit.Elements.Parmater?

Running this:

import clr

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
from Revit.Elements import ElementWrapper

parameter = IN[0]
OUT = Revit.Elements.ElementWrapper.ToDSType(parameter, True)

Causes this:

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed. 
Traceback (most recent call last):
File "<string>", line 9, in <module>
TypeError: expected Element, got Parameter
