The 1.9f vascu picc was returned for evaluation.Additional information regarding this event was requested but was not provided.Visual inspection revealed no obvious defects.Functional testing was performed.The distal lumen was clamped with hemostats and then flushed.A leak was noted approximately 3.5 cm from the hub.Under magnification it can be seen that the lumen is split longitudinally.The device was further reviewed by medcomp engineering.While the split in the lumen is visible, it cannot be determined when it occurred, noting that bunching can occur during removal of the stylet, which may have caused the damage to the lumen.It is not known how long the device was in use prior to this event.The contract manufacturer conducted a review of the manufacture records for the lot number reported.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 conducted as a last step in the manufacture process.This test would have detected any holes, tears, leaks, or weak spots if they had existed at the time of manufacture.We are unable to determine the root cause or factors that may have contributed to this event.The instructions for use (ifu) contains the following warnings and precautions: do not use infusion equipment which can exceed the working pressure of 1.0bar max/750mmhg (14.5 psi).Only use infusion equipment complying with standards, which do not exceed a shut-off pressure of 1.0bar.Bolus injections should be slow and must not exceed the maximum bolus pressure of 1.2bar/900mmhg (17.4 psi).Do not use high-pressure injectors for contrast medium studies.Excessive pressures may damage catheter.Do not use sharp instruments near the extension lines or catheter lumen.If difficulty and/or bunching of the catheter lumen are experienced while removing the stylet, additional flushing of the catheter may be helpful.The catheter may need to be repositioned to allow for removal of the stylet.Small syringes will generate excessive pressure and may damage the catheter.Ten (10cc) or larger syringes are recommended.Preflush catheter, sideport adapter, and needleless access port, if included.Attach saline filled syringe to luer of sideport adapter and flush adapter and catheter.Assure the handle of the twisted wire stylet is firmly attached to the adapter.
