An implanted elongated member, e.g., a medical lead or catheter, includes one or more conduits that are configured to accept a stylet to guide the elongated member during implantation and deliver a solidifying substance to an outer surface of the distal portion of the elongated member via one or more exit ports. Once the elongated member is correctly positioned within the patient, the stylet is removed from the conduit and the solidifying substance is delivered into the conduit. The solidifying substance is cured in situ from moisture in the surrounding tissue, UV light or some other curing method. The solidifying substance helps secure the elongated member to a target tissue site. The solidifying substance may form fixation structures that extend away from the elongated member, form an adhesive bond between the elongated member and the tissue, or inflate a balloon element that that engages with the adjacent tissue.
