The device involved in the incident was not returned for evaluation and no photographs provided.The exact location of the leak is unknown.The contract manufacturer conducted a review of the manufacture records for the lot number provided.Their investigation revealed the device was manufactured and inspected according to specification with no non-conformances or abnormalities.The manufacture process includes a 100% leak test performed as a last step in the process.This test would have detected any holes, leaks, or weak areas if they had existed at the time of manufacture.Without an evaluation of the device a root cause cannot be determined.The catheter was implanted for 48 days prior to the leak.The report indicated the patient had this line removed and received another line.In addition, it was reported the patient had a central line associated blood stream infection (clabsi).There is no indication the clabsi was associated with the patient?s death.Infection and thrombosis are the two most common complications of central line catheters, and both are noted in the instructions for use (ifu).The instructions for use (ifu) contains the following warnings and precautions that should be followed to minimize the occurrence of holes, tears, and leaks in the catheter.Do not use infusion equipment which can exceed the working pressure of 1.0 bar max/750mmhg (14.5 psi).Only use infusion equipment complying with standards, which do not exceed a shut-off pressure of 1.0 bar.Bolus injections should be slow and must not exceed the maximum bolus pressure of 1.2 bar/900mmhg (17.4 psi).Small syringes will generate excessive pressure and may damage the catheter.The use of 10cc or larger syringes are recommended.Do not use sharp instruments near the extension lines or catheter lumen.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
