The invention relates to a screwing stylet for improving torque transfer from a physician's hand to a lead tip (e.g., helix) of a lead device. A lead tip is provided to facilitate handling and a screwdriver functionality of the screwing stylet is provided to improve torque transfer to the lead tip of the lead device for better control of a puncturing process. The screwing stylet can be engaged directly with the tip of the lead device, thereby allowing a direct and efficient torque transfer to the fixed helix at the tip.
