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.Investigation summary: one 19cm hemostar d/l catheter was returned for evaluation.Visual, microscopic, and tactual tests were performed.The investigation is confirmed for a sheath stuck to catheter, as the microscopic and tactile observations appear to show the sheath on the catheter.Furthermore, the investigation is confirmed for dislodgement as the microscopic and tactile observations appear to show that the sheath is left on the catheter when it should have been on the tunneler.Although there is splitting on the damaged sheath segment it is uncertain if this is related to the procedure or post procedure.Although a definitive root cause could not be determined, excessive friction between components, incompatible dimensions, or tool damage could have potentially caused or contributed to the reported event.Labeling review: a review of product labeling documentation (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.(expiry date: 05/2021).
