A pump, two cylinders and reservoir were received for evaluation.Examination and testing of the returned components revealed the pump exhaust tubes and inlet tube were overlapping each other while in-vivo.This positioning, in combination with device usage over time, could result in sufficient stress(s) to cause the eventual separation of the pump inlet and longer pump exhaust tubes while in-vivo.Separations of these types would then allow the loss of fluid, making the device inoperable.In addition, as the device had been implanted for over 20 years.
