Manufacturer Narrative

Plant investigation: the complaint device was returned to the manufacturer for physical evaluation.The corporate provided blood port and adapter caps were attached to the dialyzer.The fibers were wet with evidence of blood exposure.During gross visual examination, a delamination was observed on the cavity id end of the dialyzer extending from approximately 85° to 290° with the dialysate ports situated at 0°.Further examination of the complaint device did not identify any other damage or irregularities.The sample was not subjected to a laboratory leak test as a delamination is known to affect the integrity of the dialyzer and cause a leak.A production records review was performed on the reported lot.An investigation of the device history records (dhr) was then conducted by the manufacturer.There was one approved temporary deviation notice (dn) reported on the lot which was unrelated to the complaint event.There was no indication of product nonacceptance, deviation, non-conformance, rework, labeling or process control failure during the manufacturing process which could be associated with the reported event.The lot met all release criteria.The investigation into the complaint was able to confirm the reported event.Continuous improvement is of the utmost importance to fresenius medical care as we strive to provide dialysis products of the highest quality to our patients.Reports of leaking product are investigated both individually as complaints, as well as via the nc/capa program, in order to assess and improve our products and processes.Capas for vision systems and blood leak reduction are recent examples of leak related investigations directed at an overall reduction in dialyzer leaks.
