A lead stabilization and extension wire that enables the withdrawal of a guide catheter over an electrical medical lead body without dislodging an electrode or sensor from an implantation site or detaching the fixation mechanism and methods of use and a kit are disclosed. The lead stabilizer and retraction wire comprises a wire sheath and an elongated core wire insertable within a sheath lumen. The sheath is insertable within a lead body lumen and includes a movable lead clamp that can engage with a lead connector element and a friction element frictionally engaging the core wire to maintain the extension wire length. The lead stabilizer and retraction wire is insertable into the lead body lumen enabling retraction of the guide catheter over the lead stabilization and extension wire while force is applied through the lead stabilization and extension wire to maintain the distal electrode at the implantation site.
