This follow-up report is submitted to fda in accord with applicable regulations.(b)(4).Visual inspection was performed on the returned sample, during which no anomalies were noted anywhere on the device.Ops valves are subject to a 100% leak test, which includes five different tests the units are run through to ensure there are no leaks and both the umbrellas and duckbills are functioning properly.Upon evaluation of the returned sample, it was found to function as intended, and met all of the product specifications.Based on the complaint description, the suction or flow through the ops valve was not able to meet the specification during an inspection at distributor facility.This is believed to be an issue with the forward flow through the duckbill valve.The reported issue was not able to be replicated; therefore, the complaint was not confirmed.All ops valves undergo 100% leak test and visual inspection.There is a known issue currently ongoing with the duckbill valve, within the ops valve, that prevents the duckbill from opening within the product specification range.It is possible that the duckbill valve did not open during the event, as reported; however, if a high enough pressure had been reached after that initial attempt, the seal in the slit of the duckbill may have been broken, allowing the valve to pass all leak tests during the evaluation of the returned sample.This was not able to be confirmed.The cause of the issue with the duckbill is due to a process change at the supplier, specifically during the washing/cleaning step.The new validated process has already been implemented at the supplier and terumo has initiated an action for removal of all affected units from the field all available information has been placed on file in quality management for appropriate tracking, trending, and follow-up.
