Manufacturer Narrative

This supplemental report is being submitted to provide the device evaluation results.The referenced device was returned in the original packaging and the lot number was confirmed as mk715070.A visual inspection was performed on the received condition found the core wire within the handle was kinked.The basket could not be deployed.Additionally the distal end was kinked just below the basket.This suggests that excessive force was applied to the device with the basket retracted.The threaded luer was unscrewed and the sheath could not be removed.The device was disassembled further, removing the wire basket and sheath assembly from the handle.The kink in the core was confirmed and the blue elastic strain relief was cut away from the assembly exposing a buckled sheath.The wrinkled sheath combined with the kinked distal end prevented the device from deploying.After disassemble the basket was manually pulled from inside the sheath.The basket was intact and free from damage.Based on the evaluation, the cause of the kinks in the proximal core and distal end are indicative of misuse.The excessive force applied to the device buckled the proximal end of the sheath preventing operation as designed.This likely occurred during insertion as the device become lodged on anatomy or caught on the scope or urethral stent.The instruction manual for device provides cautions that states, "the surlok helical stone basket is a delicate precision instrument and must be handled with care".
