1. Dec 19, 2023Class IIOpen, Classified

   Medfusion Model 4000, 3500, and 3010 pumps manufactured or serviced with Barrel Clamp Guide (Part Number G6000716), Lot Numbers P0407365, P0486670, and P0561740 may contain a molding defect that could potentially lead to slippage of the spring within the barrel clamp assembly. If this occurs, it could result in the inability of the pump to recognize a syringe or the pump may misidentify the size of the syringe loaded.

   A force sensor in the occlusion detector may drift out of calibration leading to increased occlusion detection times, false occlusion alarms, or a System Failure Alarm. If the force sensor calibration shift is large enough, the pump will display a System Failure Alarm (including Force Sensor BGND Test, Force Sensor Bridge Test, or Force Sensor Test). However, if the calibration shift is not large enough to trigger a System Failure Alarm, the threshold to detect an occlusion may increase, increasing the time to occlusion detection, or the threshold may decrease, leading to false occlusion alarms. Although shifts in the force sensor calibration may occur over time with any device, an increased potential for such shifts has been reported in devices produced before April 2022 due to mechanical interference between parts of the plunger head assembly. Out of an abundance of caution, we are notifying all customers of this potential issue.
