Additional Manufacturer Narrative
Combination product: yes.03-mar-2026 lead was explanted on (b)(6) 2026.Upon receipt, the lead under complaint was found cut 11.5 cm distal to the df4 connector pin (into 2 segments).An extraction aid was found on the distal fragment; it is reasonable to assume that the lead was cut during the surgery.The insulation was found rubbed through 7.5 cm proximal to the lead tip, which is assumed to be the root cause of the reported oversensing in the ventricular channel.Based on the characteristics of this damage, it is reasonable to assume that the lead had been subject to severe mechanical stress in the implanted state.Significant lead motion in the area of the tricuspid valve and interaction with atypical tissues should be taken into consideration.Furthermore, the fixation helix was found bent, which most likely resulted from the extraction procedure due to tensile stress.Prior to the analysis of the device, the quality documents accompanying the manufacturing process for this device were re-investigated.All production steps were performed accordingly, and in particular the final acceptance test proved the device functions to be as specified.In conclusion, the analysis did not reveal any sign of a material or manufacturing problem.
