(b)(4).Method: the device is not available for return.Information on the model and lot number was requested, however is not available at this time; a review of the device history record (dhr) cannot be conducted.Results: as the device and lot number were unavailable for analysis, no methods were performed.For this reason results cannot be obtained.Conclusions: limited information was provided by the reporter.It was reported that the pump was either a cb004 or a cb6004.The incident occurred in 2008.Since the device was not returned to halyard for evaluation, we are unable to determine the cause for the reported event.A variety of factors such as fill volume, temperature, pump position and storage times may affect the flow rate accuracy of elastomeric pumps.These factors may result in an increase or decrease in flow rate from the labeled flow rate and impact the delivery time.The instructions for use (ifu)(1304513)specificies, "cautions the amount of medication over the therapeutic period and delivery time can vary by as much as 20% due to the flow rate variation.""do not underfill pump.Underfilling the pump may significantly increase the flow rate.Filling the pump less than nominal results in faster flow rate." "temperature will affect solution viscosity, resulting in faster or slower flow rate." the ifu also specifies, "when filled to nominal volume, flow accuracy is +/- 20% of the labeled flow rate when the infusion is started 0-8 hours after fill and delivering normal saline as a diluent at 22 degrees c, 72 degrees f." information from this incident has been included in our product complaint and mdr trend reporting systems.Trend information is used to identify the need for additional investigations.
