The device history record was reviewed and showed that this device met all manufacturing specification for product released for distribution.No issues were identified that would have impacted this event.One used portal and a section of the catheter were returned for device evaluation.The catheter measured approximately 5.5 inches.Visual inspection was performed with the unaided eye, as well as under microscopy.The catheter was found broken away from where it had been connected to the portal.The proximal end of the loose catheter attached and the catheter segment were found have multiple longitudinal cracks about their ends.The device had been implanted for eight years, and this investigation was unable to determine what the device had been exposed to over time.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.
