Manufacturer Narrative

Plant investigation: the complaint device was returned to the manufacturer for physical evaluation.During the visual examination of the sample, a potted fiber fragment was observed on the non-cavity id end of the dialyzer.The fiber fragment extended from the potting surface approximately 2.37 mm in length, under magnification (x20), at approximately 220°, with the dialysate ports situated at 0°.An opposing end to the fiber fragment could not be isolated.No other damage or irregularities were noted on the returned sample.A production records review was performed on the reported lot.An investigation of the device history records (dhr) was 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.The reported lot number passed pyrogen testing, was within sterilization dosage parameters and passed all release criteria.There is no recall associated with this complaint.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 2018-0171 (vision systems) and 2018-0161 (blood leak reduction) are recent examples of leak related investigations directed at an overall reduction in dialyzer leaks.
