Titan otr pump, cylinders 1 and 2, reservoir, and detached connector / tubing were received for evaluation.Abrasion was noted on both exhaust tubes and the inlet tube of the pump.A group of partial separations, surrounded by abrasion, were noted on both exhaust tubes of the pump.These were not sites of leakage.A separation, surrounded by abrasion, was noted on the longer exhaust tube of the pump.This is a site of leakage.A group of partial separations, surrounded by abrasion, were noted on the exhaust tubes of both cylinders.These were not sites of leakage.No functional abnormalities were noted with either cylinder 1 or cylinder 2.No functional abnormalities were noted with the reservoir.No functional abnormalities were noted with the detached connector/tubing.Based on examination of the returned product, it was concluded that while in-vivo both the exhaust tubes and inlet tube of the pump had overlapped and abraded against one another.This positioning, in combination with device usage over time, could contribute to sufficient stress to separate the longer exhaust tubing of the pump.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.No trends were noted for complaints and there were no nonconforming reports or capas that were confirmed to be associated.
