Visual analysis on the returned stone cone nitinol urological retrieval coil was performed and revealed that the distal stop and distal tip were missing and were not returned.The device opened and closed with extreme resistance.The blue/green heat shrink/core wire was broken at the distal end of the cone, and the blue/green heat shrink was scorched, which appeared to be burned, at the distal end.Analysis also revealed that the cone was seemed to be stretched with very high force.The device history record (dhr) review found that the device met all manufacturing specifications.A search of the complaint database revealed that no similar complaints exist for the specified lot.During manufacturing, the devices are 100% inspected for functionality / integrity.Therefore, taking into consideration these factors and the analysis performed on the returned device, the most probable root cause is "undeterminable".
