Block h6: device code a0401 captures the reportable event of sheath broken at distal end.Block h10: the returned trapezoid rx basket was analyzed, and a visual evaluation noted that the white heat shrink is accordioned and the blue sheath cannot pass it.The blue sheath is also severely accordioned and has a break in the middle of the working length, which is exposing the inner wire.The coil was partially opened when returned and could not be opened or closed.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 test of the 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.
