A medical device is provided. The medical device includes an elongated device body having a steerable portion including a plurality of segments. The segments are co-axially mounted over at least one elongated elastic element which is configured for limiting rotation of the segments with respect to each other. The medical device also includes a control wire running alongside the elongated device body and being unrestrained at the steerable portion such that tensioning of the control wire angles the steerable portion from a longitudinal axis of the elongated device body and deflects the control wire away from the steerable portion.
