The lot number was reviewed for complaint trend, non-conforming 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 pump, cylinders 1 and 2, and reservoir were received for evaluation.Abrasion was noted on the longer exhaust tube and the inlet tube of the pump.A separation was noted on the pump bulb.This is a site of leakage.The surfaces appear to be non-striated, dull, and smooth, indicating that sufficient stress(s) was exerted.Abrasion was noted on both exhaust tubes of the cylinders.A separation was noted on the bladder of cylinder 1.This is a site of leakage.The separation has a central groove, indicating contact with sharp instrumentation such as a needle.A group of striations, indicating contact with unshod instrumentation, was noted on the exhaust tubing of cylinder 2.This is a site of leakage.A group of striations, indicating contact with unshod instrumentation, was noted on the inlet tube of the reservoir.This is a site of leakage.Based on examination of the returned product, it was concluded that the non-striated, dull, and smooth surfaces associated with the separation indicate that sufficient stress was exerted on the pump bulb.A separation of this type could 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 on both cylinders and on the reservoir inlet tubing 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 separations most likely occurred during or after 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.No trends were noted for complaints and there were no nonconforming reports that were confirmed to be associated.
