Additional Manufacturer Narrative
Combination product: yes.Upon receipt, the lead under complaint was found cut 52.5 cm proximal to the lead tip.The distal fragment was received for analysis.An extraction aid was found on the distal fragment, it is reasonable to assume that the lead was cut during the surgery.The rv shock coil, distal ring electrode and fixation helix were found covered in fibrotic growth.The calcification can be assumed to be the root cause of the reported increasing impedance and thresholds.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.
