One epidural catheter was returned for evaluation.Upon visual inspection, device was found to have smooth, round tip as well as catheter eyes were present and properly formed.A dried substance was noted to be present throughout the inside of the catheter.As functional testing, attempts were made to push fluid through the catheter after assembling it to a connector to observe for flow from the catheter eyes.This test was not successful due to the dried substance inside the catheter which impeded flow, confirming the reported customer complaint.The returned catheter was also tested for proper fit.The distal tip of the catheter was passed through the hub of the needle until it passed through the bevel tip.A slight resistance was observed as the tip of the catheter emerged from the bevel of the needle.However, this is considered to be an acceptable fit.While no definitive root cause to the reported issue could be determined, this investigation revealed no intrinsic evidence to suggest a root cause related to manufacturing.
