(b)(4) the customer reported the epidural catheter broke during removal.The customer returned one catheter adapter and two epidural catheter pieces.The components were received connected.The returned components were visually examined with and without magnification.Visual exanimation of the returned catheter adapter revealed the adapter appears typical with no observed defects or anomalies.Visual examination of the returned catheter pieces revealed on the likely most proximal piece, the extrusion is stretched, and coil wire is extremely stretched at the likely distal end with the coil wire extending approximately 8.8cm beyond the extrusion.The extrusion and coil wire on the likely most distal piece are also stretched at the point of separation at the likely proximal end.Also, both the proximal and distal ends of the returned catheter pieces appear to be intact.The catheter appears to have been used as biological material can be seen between the inner coils.No other defects or anomalies were observed.A dimensional inspection was performed on the catheter using a ruler.The proximal end catheter extrusion piece measures approximately 66.8cm.The distal end catheter piece measures approximately 28.0cm.Both catheter pieces combine to measure approximately 94.8cm.None of the catheter appears to be missing.However, with the coils and extrusion being stretched, this is why the catheter is outside of the specification.A device history record review was performed on the epidural catheter with no relevant findings.The ifu for this kit, 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 reattempt removal if resistance is encountered or if catheter stretches excessively during removal." the reported complaint of epidural catheter breaking during removal was confirmed based upon the sample received.The customer returned two catheter pieces that were separated at the extrusion.None of the catheter appeared to be missing.At the point of separation, the extrusion and coil wire were stretched on the likely proximal piece and was also stretched on the likely distal piece.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.Therefore, based upon the condition of the sample received, unintentional user error caused or contributed to this event.No further action is required at this time.
