In one embodiment, an implantable medical lead includes a lead connector end, a tubular body, at least one electrode and at least one fixation structure. The lead connector end is configured to couple to the implantable pulse generator. The tubular body extends distally from the lead connector end and includes a distal portion distally terminating in a distal end. The at least one electrode is located on the distal portion. The at least one fixation structure is located on the distal portion and includes a bioabsorbable metal. For example, the bioabsorbable metal may be iron, an iron alloy with 35% manganese, or a magnesium alloy. The bioabsorbable metal is configured such that the at least one fixation structure will last long enough at an implantation site so as to secure the distal portion of the tubular body in place via fibrotic tissue.
