Titan touch pump, cylinders 1 and 2, and reservoir were received for evaluation.Abrasion was noted on both exhaust tubes and the inlet tube of the pump.No functional abnormalities were noted with the pump.Abrasion was noted on the exhaust tubing of cylinder 1 and cylinder 2.A separation was noted on the bladder of cylinder 1.This was a site of leakage.The separation had surfaces with a darkened or melted appearance, indicating contact with a cauterizing tool.A separation was noted on the bladder of cylinder 2.This was a site of leakage.The separation had surfaces with a darkened or melted appearance, indicating contact with a cauterizing tool.No functional abnormalities were noted with the reservoir.The information received indicated the device had a tear in the tubing, but because no functional abnormalities other than instrument damage were noted with the returned components, the complaint could not be confirmed as reported.Because these components were released according to manufacturing and quality control procedures, it was concluded that the observed burn-mark instrument separations in the bladder of cylinder 1 and cylinder 2 occurred after the device packaging was opened.In addition, because the expected use of this device combined with the observed separation would have resulted in an earlier detected fluid loss, it was concluded that the separations most likely occurred during or after explant.These separations are not associated with the cause for failure.A review of the device history record confirmed the devices from this lot met all specifications prior to release.A review of the complaint history database, nonconformance's and capas revealed no trends for this lot.
