Additional Manufacturer Narrative
The returned valve was patent.The valve met the requirements for reflux, and leak testing.However, it did not meet the requirements for pressure-flow and preimplantation testing.There was proteinaceous debris noted in the interior and exterior of the device.Debris within the valve may hold pressure-flow controlling mechanisms open affecting the flow of fluid through the valve.The instructions for use (ifu) that accompany the device caution that ¿shunt obstruction may occur in any of the components of the shunt system.The system may become occluded internally due to tissue fragments, blood clots, tumor cell aggregates, bacterial colonization, or other debris.¿ also, the instructions for use describe the patency test procedure for csf burr hole valves as follows: depress the valve dome, place a finger over the opening at the end of the outlet connector and release the depressed dome.If fluid enters the reservoir, the inlet connector and flow control membrane valve are patent.Following that, remove finger from the outlet connector opening and depress dome.If fluid flows out of the outlet connector, the valve is patent.A review of the manufacturing records showed no anomalies.All valves are 100% tested at the time of manufacture.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
Event or Problem Description
It was reported to medtronic neurosurgery that during testing prior to implantation, the physician attempted to pump the valve inside saline solution, but noticed there was no fluid flow.According to the report, the valve was replaced with a new valve and the procedure was completed without any complication.There was no injury to the patient.
