A manipulator joined to a distal end of a delivery system shaft includes a plurality of arms and a collar. A proximal portion of each of the arms is joined to the shaft and a distal portion of each of the arms is joined to the collar such that the collar is substantially aligned with a lumen of the shaft. The lumen and the collar slideably and rotatably engage a medical electrical lead while a plurality of control wires, adapted to manipulate the manipulator, join to each of the plurality of manipulator arms in proximity to the distal end of the shaft.
