The following were reviewed as part of this investigation: patient severity, frequency analysis, applicable previous investigation(s), sample (if available), applicable fmea documents, labeling, and applicable manufacture records.Based on a review of this information, the following was concluded: the report of a slit in the catheter is confirmed, and the cause is determined to be likely use-related.The samples returned were one 19 cm hemostar dialysis catheter and one photograph of the device as inserted in the patient.The photograph showed the device inserted into the patient, with no bleeding apparent.Visual observation confirmed the discoloration reported in the original complaint.There was clear accumulation of biological material on the cuff.A transverse slit in the catheter was found on the venous side of the catheter just distal to the cuff.Some solid residue was found inside the lumen exposed by the slit.Functional testing found both lumens patent to infusion, and that the venous lumen would leak during infusion from the slit next to the cuff.Microscopic observation found that the slit edges were very clean, and the slit was straight for the majority of its length.If the slit had been present in the catheter during dialysis, it would have resulted in significant bleeding, and if not present during dialysis but during use, it would likely have caused noticeable bleeding.However, it was not mentioned in the original complaint, and was therefore likely caused during or after removal.The slit has the appearance of a cut with a sharp instrument, and being distal to the cuff, this is suggestive of being caused during the loosening of the cuff during removal, during which procedure a sharp instrument may be used for trimming tissue away from the cuff.However, it appears that in conjunction with a similar event for a similar device reported in complaint (b)(4), from the same facility, based on information from the customer, a cut was made at the extension leg in order to identify the white material composing the discoloration.Therefore, it is considered possible that this cut was made intentionally by the user.
