The device has been received at coloplast; however the evaluation is not yet complete.Without the benefit of examination and testing, coloplast is precluded from commenting on the condition of the device or the cause of the occurrence.Once our evaluation is complete, a follow-up report will be submitted.

This follow-up mdr is created to document the evaluation of the returned device.A titan otr pump, two cylinders and a reservoir were received for evaluation.Examination and testing of the returned components revealed a separation in the inlet tube of the pump.Testing revealed this to be a site of leakage.Microscopic examination of the surfaces revealed them to be rough and irregular, indicating stress was exerted.Two separations were noted in the pump bulb.Testing revealed these to be sites of leakage.Microscopic examination of the separations revealed both to have a central groove, indicating contact with sharp instrumentation such as a needle.A separation was noted in the bladder of cylinder 1.Testing revealed this to be a site of leakage.Microscopic examination of the surfaces revealed them to have uniform striations, indicating contact with sharp instrumentation.A separation was noted in the bladder of cylinder 2 near the base.Testing revealed this to be a site of leakage.Microscopic examination of the surfaces revealed them to have a melted appearance, indicating contact with cauterizing instrumentation.Abrasion was noted on all tubes of the pump and inlet tube of the reservoir.No functional abnormalities were noted with the reservoir.Based on examination of the returned product, it was concluded that while in-vivo all pump tubes had overlapped and abraded against one another.This positioning, in combination with device usage over time, could contribute to sufficient stress(s) to separate the inlet 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 separations noted in the pump bulb and both cylinder bladders occurred subsequent to the device packaging being opened.In addition, because the expected use of this device combined with the observed separations would have resulted in an earlier detected fluid loss, it was concluded that the separations most likely occurred during or subsequent to 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, nonconformances and capas revealed no trends for this lot.
