Manufacturer Narrative

Block h6: device code a0401 captures the reportable event of sheath break at the distal end.Block h10: the returned trapezoid rx basket was analyzed, and a visual evaluation noted that the blue sheath was torn towards the proximal end allowing the core wire to show.No other notable defects noted.The reported event was confirmed.Based on all available information, it is most likely that the damage was caused during the testing of device with the use of excessive force or manipulation.Therefore, the most probable root cause is unintended use error.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.
