Manufacturing review: a dhr review is not required, however it was requested.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: the device returned was one 10 fr d/l 90 cm leonard catheter with surecuff complete.Functional, microscopic, tactual, and visual evaluation was performed.A w-shaped split with granular fracture surface was found immediately distal to the bifurcation, which is consistent with a burst.Therefore, the investigation is confirmed for an external leak, more specifically an external burst.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.However, overpressurization, including use of a syringe smaller than 10 ml, is a known cause of bursts and may have contributed to this event.Labeling review: a review of the product instructions for use (ifu) procedural instructions, indications, warnings, precautions, cautions, possible complications and contraindications showed that the product labeling is adequate.(expiry date: 10/2022).
