Systems for providing stimulation with an implantable system control unit and for optimally positioning that system control unit include a system control unit configured to provide a stimulus to a patient with a member attached to the system control unit for pulling the system control unit into position within the patient. Methods of optimally positioning the implantable system control unit within a patient such that the system control unit is proximal to target tissue that is to be stimulated by the system control unit include threading a member through a patient's body using a needle, the member passing proximal to the target tissue and being attached to the system control unit, and pulling the system control unit into place with the member.
