A patient underwent generator replacement surgery due to battery depletion, and had their leads replaced prophylactically so that they could be compatible with the latest generator models.The explanted devices were returned for analysis.Analysis of the returned lead segments indicated dried remnants of what appeared to have once been body fluids inside the inner and outer silicone tubing.Abraded openings were noted on the inner and outer silicone tubing of the returned lead portion.The abraded openings appeared to have most likely provided the leakage path for the dried remnants mentioned.Other than the inner and outer tubing abrasions and typical wear and explant related observations, no other anomalies were identified in the returned lead portions.Analysis of the returned generator identified no anomalies.No further relevant information was received to date.
