The following were reviewed as part of this investigation: patient severity, applicable previous investigation(s), sample analysis, applicable fmea documents, applicable manufacturing records, and labeling.Based on a review of this information, the following was concluded: the complaint of a damaged stylet wire was confirmed, and it appeared that the wire was inadvertently cut.One stiffening stylet was returned for investigation.The stylet wire was received without the t-lock extension set.The distal end of the coil wire was extending beyond the distal tip of the core wire.A microscopic examination revealed that the weld tip was not present at the distal tip of the stylet wire.The distal tip of the core wire exhibited regions of increased luster, which indicates that the wire was sheared with a sharp instrument.The core wire extended 41.1cm from the distal end of the black tab, which indicates that 0.4 to 1.4 cm of the stylet wire was missing.When modifying the catheter length, the ifu states, ¿retract the stylet to well behind the point the catheter is to be cut.Using a sterile scalpel or scissors, carefully cut the catheter according to institutional policy, if necessary.Caution: the stylet or stiffening wire needs to be well behind the point the catheter is to be cut.Never cut the stylet or stiffening wire.¿ the ifu also indicates that the t-lock extension set and stylet wire should be removed as a unit.
