Event or Problem Description
The nurse reported that probe could not cut before the surgery.The surgery was completed after replacing the product with another probe.There was no patient harm.The procedure type was unknown.
Additional Manufacturer Narrative
One opened probe was received, with a tip protector, in a pouch, for the report.The sample was visually inspected and found to be nonconforming with orange/brown foreign material on the port face and body detached from the engine assembly.The sample was then functionally tested for actuation and cut.The sample was found to be conforming for both functional tests.A review of the device history record traceable to the lot number obtained from the device¿s radio frequency identification (rfid) tag, indicates that the reported product was processed and released according to the reported product¿s acceptance criteria.The returned sample was found to be functionally conforming, therefore a cut failure as described in the complaint was not confirmed and a root cause cannot be determined for the complaint as described by the customer.No action was taken as the returned probe was functionally conforming.All probes are 100% visually inspected and tested for actuation, aspiration, and cut during manufacturing.Complaints are reviewed and monitored at regular intervals for any significant adverse trends.No adverse trends have been observed associated with the reported product and event.The manufacturer internal reference number is: (b)(4).
