The disclosure is directed to securing electrodes of a medical lead adjacent to a target tissue site. The medical lead may include at least one adhesive element disposed along a longitudinal outer surface of the lead body to adhere the adjacent tissue to the lead. Adhesive elements may be disposed proximal to, distal to, or in-between the electrodes of the lead. Each adhesive element may be inactive during lead implantation and activated by removing a covering sheath to expose the adhesive elements to moisture in the tissue or presenting an energy, e.g. ultraviolet light, to the adhesive elements. Once active, the adhesive elements secure the lead to surrounding tissue to prevent migration of the electrodes from the target tissue. |
