A titan otr pump, two cylinders, and detached inlet tubing were received for analysis.A separation was noted through the longer pump exhaust tube.This was a site of leakage.The surfaces of this separation appear to be rough and irregular, indicating stress was exerted.A partial separation was noted on the shorter exhaust tube of the pump.This was not a site of leakage.Abrasion was noted on the inlet tube of the pump.Partial separations within abrasion were noted on the exhaust tube of cylinder 1.This was not a site of leakage.Abrasion was also noted on the exhaust tube of cylinder 2.No functional abnormalities were noted with either cylinder.No functional abnormalities were noted with the detached inlet tubing.Based on examination of the returned product, it was concluded that the rough and irregular surfaces associated with this separation indicates that sufficient stress(s) may have been exerted on the longer exhaust tube of the pump to separate the site while in-vivo.A separation of this type could then allow the loss of fluid, making the device inoperable.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, nonconformances and capas revealed no trends for this lot.
