Event Description
|
It was reported by the user facility that a patient underwent an ureteroscopy with laser lithotripsy procedure.The device in use was the ngage nitinol stone extractor.The attending physician indicated that the stone extractor was deployed and used for extractions a couple of times before it would no longer completely close.The physician had repositioned the stone prior to the basket failure, and so instead of removing fragments with the basket, he used the laser to fragment the stones small enough to pass on their own.There were no additional procedures performed due to the basket not closing.There were no unintended sections of the device that remained inside of the patient¿s body, nor did the patient experience any adverse effects due to this occurrence.No further information was provided.
