One opened probe was received, with a tip protector along with the needle/stiffener in a container, in a bubble bag, for the report of probe coming apart during surgery.The sample was visually inspected and found to be nonconforming with the probe needle/stiffener pulled out of the needle holder.Inner cutter was observed to be bent.The probe was disassembled and the components inspected.No/minimal wear on inner cutter when compared to the degree of wear based on continuous actuation of the probe visual standard photos.Gouges marks observed at one location on the inner cutter.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 photo shows two probes distal ends, on the left probe the inner cutter is visible and the probe needle and stiffener is moved out from the original position.The complaint evaluation confirms the report of probe coming apart.The root cause for the component detachment is the adhesive bond failure which caused the needle assembly to detach from the rest of the probe assembly.An internal investigation was completed and improvements to the adhesive bond have been identified.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 further actions are required.The manufacturer internal reference number is: (b)(4).
