The lot number was reviewed for complaint trend, nonconforming report and capa.Devices met specification prior to release and no trends were noted.Without the benefit of examination and testing, coloplast is precluded from commenting on the condition of the device or the cause of the occurrence.Should additional facts prompt us to alter or supplement any information or conclusions contained in the original mdr or in any prior supplemental reports, a follow-up report will be submitted.

Titan otr pump, cylinders 1 and 2, and detached inlet tubing were received for evaluation.Abrasion was noted on both exhaust tubes and the inlet tube of the pump.The surfaces of the detachment site of the shorter exhaust tube of the pump appear to be rough and irregular, indicating stress was exerted.Abrasion was noted on the exhaust tubes of cylinder 1 and cylinder 2.A group of partial separations, surrounded by abrasion, were noted on the exhaust tubes of cylinder 1 and cylinder 2.These were not sites of leakage.The surfaces of the detachment site of exhaust tube of cylinder 2 appear to be rough and irregular, indicating stress was exerted.A separation was noted on the bladder of cylinder 2.This is a site of leakage.The separation has a smooth, straight edge, indicating contact with sharp instrumentation.No functional abnormalities were noted with the detached inlet 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.While no functional abnormalities were noted during testing with the returned components, microscopic examination of the surfaces of the exhaust tube detachment end between the pump and cylinder 2 revealed rough and irregular surfaces, indicating stress was exerted.Based on the overlapping of the pump tubes, in combination with device usage over time, this could contribute to sufficient stress to separate the exhaust tubing of the pump.A separation of this type would then allow the loss of fluid, making the device inoperable.Because these components were released according to manufacturing and quality control procedures, it was concluded that the observed instrument separation in the bladder of 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 separation most likely occurred during or after explant.This separation is 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, nonconformances and capas revealed no trends for this lot.
