The patient underwent prophylactic battery replacement for the desire to have an m106.The explanted devices were returned for analysis.Product analysis on the lead was completed and approved.Note that the electrodes were not returned for analysis and therefore a complete evaluation could not be performed on the entire lead product.The abraded openings found on the outer and inner silicone tubes, most likely provided the leakage path for the dried remnants of what appeared to have once been body fluids found inside the outer and inner silicone tubing.What appeared to be white deposits were observed in various locations.Eds (energy dispersion spectroscopy ¿ provides chemical or element identity/composition analysis) was performed on the deposit observed on the outer silicone tubing and identified the deposit as containing silicon, phosphorus, sodium, magnesium, sulphur and calcium.The condition of the returned lead portion is consistent with conditions that typically exist following an explant procedure.No obvious anomalies were noted.The setscrew marks found on the lead connector pins provide evidence that, at one point in time, a good mechanical and electrical connection was present.Continuity checks of the returned lead portion were performed, during the visual analysis, with no discontinuities identified.Product analysis on the generator m104 was completed and approved.A comprehensive automated electrical evaluation showed that the pulse generator performed according to functional specifications.There were no performance or any other type of adverse conditions found with the pulse generator.Review of the datadumps shows no issues with high impedance.No additional or relevant information has been received to date,.
