Pentax issued an Urgent Medical Device Correction and Removal notification informing customers of its voluntary recall of all ED-3490TK duodenoscopes in order to replace the forceps elevator mechanism, O-ring seal and distal end cap, and to update the Operation Manual to recommend annual maintenance. The design changes are intended to reduce the potential for leakage of patient fluids into the closed elevator channel and under the distal cap. Read the FDA safety alert.
