Device analysis: product analysis confirmed the reported allegation of pump not working.The returned pump failed the inflation test, while the report of a dimpled pump and the pump staying flat was not observed during the analysis, the identified functional failure indicates that the pump was not functioning correctly and it is probable that this malfunction manifested itself in the patient as a dimpled pump and is the most probable cause for the report of pump not working.Based on this investigation, the investigation conclusion code of cause traced to component failure was chosen because the reported events could be traced to a component failure through product analysis.Based on the results of this investigation, no escalation is required.
