Manufacturer Narrative

Investigation: a review of the device history record (dhr) for this unit showed non circularities during manufacturing that were relevant to this issue the run data files (rdfs) were analyzed for this event.Root cause: signals in the rdfs show there were minor signs of clumping in the collect port for both procedures.The images were reviewed for both procedures and there were a few images that were indicative of platelet clumping in the collect port.The inlet:ac ratio was at 12:1 throughout the procedure without any adjustments.If there are any signs of clumping during the procedure, it is suggested to decrease the ac ratio temporarily until the clump is cleared, and to assess the reservoir filter for excessive clumping that could cause an obstruction i the reservoir.It is also possible that the clumping may be patient related.The likelihood for platelet clumping to occur during a run is difficult to predict since it is not dependant on a specific platelet count and varies by patient.Therefore, every procedure should be observed for platelet clumping in the connector or the collect port.
