Manufacturing review: the device history records have been reviewed and this lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Labeling review: a review of product labeling documents (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) showed that the product labeling is adequate.Investigation summary: although the sample was not returned for evaluation, two x-rays were provided for review.The investigation is confirmed for the failure mode of catheter detachment as the catheter was found to have migrated to the svc and the right atrium, with no tubing left on the port connector.Image: a port catheter has the expected position.The cranial turn in the catheter tubing is not seen.The catheter tubing is not pushed very far into/on to the port connection making the connection between the two tenuous.Image: a break in the tubing is not seen.The port is in appropriate position.The catheter tubing has migrated to the svc and right atrium.No residual tubing is left on the port connector.On the fluoroscopic image of the catheter placement the catheter tubing is not pushed very far into the port connection.The definitive root cause could not be determined based upon available information.It is unknown if patient and/or procedural issues contributed to the reported event.Potential causes include inadequate connection strength during routine use, incorrect connection method (e.G., advancing the catheter lock with black ring facing port, catheter lock crooked when advanced, catheter mushroomed), and use of sutures around/through the catheter.
