Based on the reported information, there was no death nor did this result in a serious injury, as defined by the fda.This was not life-threatening, nor did this result in permanent impairment or necessitate medical or surgical intervention to preclude permanent impairment.However, the malfunction of the device could lead to an adverse event if the malfunction were to recur.The laser lot number on the device assembly was 15105475.A device history review was completed and no anomalies were observed.Analysis of the returned device included a visual and functional evaluation.Examination determined that the returned device was very worn and discolored, with excessive growth and fungus throughout the length of the device.During our inspection, the entire distal end of the tubing was found clogged by a thick and solid brown substance.The tubing support was found detached and had partially migrated from the tubing and deformed.The tubing was found with adequate adhesive in the tubing support area.The failure of the device is not believed to be due to a manufacturing defect, but due to prolonged or harsh use.As the entire distal end of the tubing was clogged, preventing the tubing from being used, it is likely that excessive pressure was exerted on the tubing if clog removal was attempted.In addition, the clogged tubing would have prevented a guidewire from pushing through the device.It is also likely that the excessive substance build-up and fungus growth throughout the device weakened the device over time, allowing the tubing support to separate from the tubing.This type of failure has never been seen before and is considered an isolated event, not caused by a manufacturing defect.Additional information was requested and a follow up report will be submitted if we are able to obtain any of the requested information.(b)(4).

The g-jet device was in use for about 2-3 months and the parents felt that it was plugged.Ir took an x-ray before removing it and thought it looked disrupted at the distal tip.They tried to thread a guidewire, but met resistance and couldn't thread it.When they pulled the tube out, it was discovered that the end of the tubing support had migrated and deformed.There was no reported harm of the patient.
