3 of 3 reports.Other mfg report numbers: 3013886523-2021-00352, 3013886523-2021-00353.A physician reported enlargement of the ventricles of a patient with a bactiseal catheter.The catheter was used together with the 823073 (catheter) and 823162 (hakim valve).The valve was implanted to the patient via v-p shunt this year with unknown setting.The enlargement of ventricles was confirmed, therefore, the set pressure was changed.After several days there was no change in the ventricles.The catheter was also replaced on (b)(6) 2021.

Udi: (b)(4).The bactiseal catheter was returned for evaluation: failure analysis - the catheter was visually inspected; no defect was noted.It was noted that only 23mm of distal catheter attached to the valve was received.When detached, only 14mm of catheter was available for testing.The catheter was irrigated and no occlusion was noted.The catheter was leak tested and passed.No leakage was noted.Note that due to the short length of catheter and because of connectors length, only about 6mm of catheter was leak tested.No issue was noted.No root cause could be determined as the technician could not confirm any problem at the time of investigation with the little piece (23mm) of distal catheter returned.The possible root cause for the "enlargement of the ventricles" reported by the customer could be due to biological debris and protein buildup interfering with the device.But, at the time of investigation, no occlusion issue was noted.As noted in the "ifu", in the section 'complications': "in addition, shunt revisions have been necessitated by the following complications associated with peritoneal catheters: subcutaneous kinking, fracture, obstruction of the distal end, and retraction of the distal end from the peritoneal cavity".
