Manufacturer Narrative
(b)(4). Manufacturing site evaluation: investigation on-going. Additional information / investigation results will be provided in a supplemental report.
 
Event Description
It was reported that a progav shunt system was explanted due to a malfunction. A (b)(6) patient underwent a shunt system implantation on (b)(6) 2018. After 1 month, it was noted that the valve was blocked. This issue led to explantation of the device. Further details have been requested but not yet received.
 
Manufacturer Narrative
All parameters have been inspected and approved during the manufacturing process. All parameters have been assessed as meeting specifications. No significant deformations or damages of the valves were detected during the visual inspection. A permeability test has indicated that the shunt assistant has a blockage and the progav 2. 0 valve is permeable. The progav 2. 0 valve was tested and is adjustable to all specified pressures. The brake functionality test has shown that the brake function is fully operational and the braking force is within the given tolerances. We have dismantled the valves. Inside both valves we have found a build up of substances (likely protein). Based on our investigation, we confirm the presence of occlusion in the shunt assistant, likely due to the deposits observed in the valve. The deposits observed inside the progav 2. 0 might also have contributed to the malfunction in the past. As described in out literature, the problem encountered is one of the known, inevitable risks of hc- therapy by shunt implants.
