(b)(4).A device history record review could not be performed as no lot number was provided by the customer.A review of sales history data was performed to obtain a lot number.However, no record could be found.The customer reported the catheter separated when the catheter was being removed from the patient.The customer returned one snaplock adapter and one catheter piece.The components were received connected together (reference files (b)(4)).The returned catheter piece was visually examined with and without magnification.Visual examination of the returned snaplock adapter revealed that the snaplock appears typical with no observed defects or anomalies.Visual examination of the returned catheter revealed the distal tip is not present on the returned catheter piece and the extrusion appears to have been separated at the distal tip.The extrusion and coils on the likely most distal end are stretched; however, the coil does not stretch beyond the extrusion at the point of separation.The proximal side of the catheter appears to be intact as no damage was observed.The extrusion and coils appear to be damaged at approximately 18.5cm and 79cm from the proximal end.The catheter appears to have been used as adhesive other remarks: residue is present on the catheter body exterior.No other defects or anomalies were observed (reference files (b)(4)).A dimensional inspection was performed on the returned catheter piece using a ruler ((b)(4)).The returned catheter extrusion piece measures approximately 108cm.Although, the specification per graphic (b)(4) rev.8 indicates that the proper length of an epidural catheter is 88.5-91.5 cm, part of the catheter is missing based on the condition of the sample received.The extrusion and coils are extremely stretched at the likely distal most end of the returned catheter.Specifications per graphic (b)(4); rev.8 were reviewed as a part of this complaint investigation.The ifu for this kit, (b)(4); rev.02, was reviewed as a part of this complaint investigation.The ifu warns the user, "never tug or quickly pull on catheter during removal from patient to reduce risk of catheter breakage.Do not apply additional tension on the catheter if catheter begins to stretch excessively.Reposition patient to open the vertebral interspaces and re-attempt removal if resistance is encountered or if catheter stretches excessively during removal.During epidural catheter removal , the literature indicates a force of approximately 1/3 of a pound is all that is necessary to exert if patient is properly positioned in the recommended lateral neutral position." a corrective action is not required at this time as the condition of the sample received indicates operational context caused or contributed to this event.The reported complaint of the epidural catheter breaking during removal was confirmed based upon the sample received.The returned catheter was missing the distal end.The catheter showed signs of stretching at the point of separation at the likely most distal end.The ifu for this product warns the user not to apply additional tension if the catheter begins to stretch as there is a risk for separation.The ifu for this product also indicates not to alter the catheter in anyway.Therefore , based upon the condition of the sample received and the observed evidence of stretching at the point of separation, operational context caused or contributed to this event.
