A system for remotely controlling the positioning within the body of a patient of an elongated medical device optionally having a control handle, comprises a robotic system and a remote controller configured to control the robotic device. The robotic system comprises a handle controller; a sled member coupled to the handle controller, the sled member being configured to position the medical device within the body of the patient; and a sled base configured to advance the sled member towards the body of a patient, the sled bed being coupled to a sterile barrier effective to maintain sterility inside the sled base. A medical device introducer is effective to guide the elongated medical device into a patient's body.
