Block g2: medwatch # mw5099515.Block h2: additional information: b3 (date of event), block b5 (describe event of problem), block e4 (init rptr also sent rep to fda), block g2 (report source), block h6 (patient codes).Block h6: device code a0501 captures the reportable event of basket wire detached.Device code a27 is being used to capture the reportable event of additional procedure required.Block h10: a picture of the device pouch/label was submitted but no device failures could be visualized.Visual analysis found only one basket wire was attached to the device which confirms the reported event.The rest of the basket was not returned.The sheath was found torn at the distal section adjacent to the basket.Microscopic inspection found there is an indication that a laser or a similar tool burned the sheath and the pull wire at the distal section.Functional assessment cannot be performed due to the returned device condition.Based on all available information, it is likely that the problem happened due to manipulation of the device by the user.The sheath was found torn and presents evidence of burned material at the distal section adjacent to the basket.This condition could have been caused by a laser or a similar device.Additionally, because of this condition, the basket detached.The instructions for use (ifu) states "warnings: this device should not be directly fired upon by any lithotrite.To do so may damage the device and could result in patient injury.This device must not come in contact with any electrified instrument." therefore, the most probable root cause is unintended use error caused or contributed to event.A review of the device history record (dhr) confirmed that the device met all material, assembly, and product specifications at the time of release to distribution.A labeling review was performed, and there is evidence that the device was used not in accordance with the instructions for use (ifu) / product label, as the device has evidence of being fired upon with a laser.
