Titan touch pump, cylinders 1 and 2, reservoir, and connector / tubing 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 both exhaust tubes of the cylinders.No functional abnormalities were noted with either cylinder 1 or cylinder 2.Abrasion was noted on the inlet tube of the reservoir.A separation was noted on the inlet tube of the reservoir near the strain relief junction.This is a site of leakage.The surfaces appear to be rough and irregular, indicating stress was exerted.Abrasion was noted on the detached connector/tubing.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 inlet tube of the reservoir.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.
