The 2.6f vascu picc was returned for evaluation.Visual inspection revealed no obvious defects.Functional testing was performed by clamping the distal end of the lumen with hemostats.When flushed through the luer with the red clamp no leaks were noted.When flushed through the luer with the white clamp a leak was noted in the lumen approximately 0.5 cm distal to the hub.Under magnification it was noted that the leak is from a small rupture in the lumen running lengthwise.The edges of the rupture appear wavy and rippled, suggesting the lumen bulged prior to bursting, possibly due to flushing against resistance.No lot number was provided.Without a lot number a review of the manufacturing records is not possible.The manufacturing process includes a 100% leak test performed as a last step in the process.This test would have detected any leaks, holes, or weak spots if it had existed at the time of manufacture.A root cause cannot be determined but is most likely not manufacturing related.The instructions for use (ifu) contain the following warnings: 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).Small syringes will generate excessive pressure and may damage the catheter.The use of 10cc or larger syringes are recommended.Do not flush against resistance.If the lumen will neither aspirate nor flush, and it has been determined that the catheter is occluded with blood, follow institutional declotting procedure.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.
