Event Description

A physician reported that the cutter did not actuate during a procedure.The condition of aspiration is unknown.The product was replaced and the procedure was completed.There was no patient harm.

Manufacturer Narrative

One opened probe was received for evaluation.The returned sample was visually inspected and found non-conforming with orange/brown foreign material on the welded cap of the needle.The sample was then functionally tested for actuation, aspiration and cut.The sample was found conforming for aspiration and was non-conforming for actuation and cut.The probe was disassembled and the components inspected.No/minimal wear was observed on the inner cutter when compared to the degree of wear based on continuous actuation of the probe visual standard photos.The cutting edge of the inner cutter was observed to be damaged.No wear marks were observed on the inner cutter.The sample was retested for actuation with the probe driver and was able to actuate.The initial actuation test failed due to an interference within the probe and once the interference (needle and shell assembly) was removed the probe was able to actuate.A review of the device history record traceable to the reported lot number indicates that the product was processed and released according to the product¿s acceptance criteria.The complaint evaluation confirmed that the probe had an actuation failure, and also indicated that the probe had a cut failure.The most likely root cause for the poor cutting is the observed damage to the inner cutter of the probe.A damaged inner cutter can impede the movement of the cutter shaft, causing to probe to not be able to perform the cut and decreasing the quality of the cut performed by the probe.How and when the inner cutter of the probe became damaged cannot be determined form this evaluation.No specific action with regard to this complaint was taken by the manufacturing site because the exact root cause for the actuation and cut failures cannot be determined from this evaluation.All probes are 100% tested for actuation, aspiration, and cut during manufacturing.Complaints are reviewed and monitored at regular intervals for any significant adverse trends.No additional action is required at this time.The manufacturer internal reference number is: (b)(4).
