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 3cg stylet was confirmed.One 3cg stylet was returned for investigation.The stylet was received within the t-lock extension set.A break in the polyimide tubing was observed 4.1cm from the distal tip of the stylet.The core wire extended 11mm from the break in the distal segment of the polyimide tubing.The core wire was curled just proximal to the polyimide tubing.Five kinks were observed within the proximal segment of polyimide tubing.Ten kinks were observed in the distal segment of polyimide tubing.The adjacent surfaces at the distal end of the broken polyimide tubing appeared uneven and granular.The wall thickness of the polyimide tubing was within specification.Kinking of the polyimide tubing and advancement against resistance may have been potential contributing factors in the observed damage; however, the exact cause of the reported event could not be determined.The ifu for the 3cg stylet states, ¿ensure that the stylet tip does not extend beyond the trimmed end of the catheter.Extension of the stylet tip beyond the catheter end, combined with kinking and excessive forces, may result in vessel damage, stylet damage, difficult removal, stylet tip separation, potential embolism and risk of patient injury.¿ a lot history review (lhr) of redx1890 showed no other similar product complaint(s) from this lot number.
