The lot# could not be confirmed since no original packaging was returned with the device.The device was returned in a small bag (6"x 11")coiled inside about 4 times.Visual inspection revealed the wire and outer sheath had been cut part way through the heat shrink and were separate from each other.The thumbslide was in the deployed position and moves easily until the bent core wire portion left in the handle catches on the heat shrink.The outer sheath was cut 13/16" from the end of the heat shrink and the wire 1" from the end of the heat shrink.The basket appears to be in good condition.The wire twists at the disc are uniform.Further inspection of the sheath found a kink at 5 1/2 inches from one end.It does not appear that there is any material missing from the outer sheath or core wire.It doesn't appear that there was any device failure but rather the issue was a large stone in a part of the anatomy too small to remove it.The staff had to cut the device apart and make the stone smaller in order to remove the basket from the patient.The customer's complaint could not be reproduced due to the condition of the device.It doesn't appear that there was any device failure but rather the issue was a large stone in a part of the anatomy too small to remove it.The staff had to cut the device apart and make the stone smaller in order to remove the basket from the patient.
