As reported the user did not cut the inflation tube prior to pulling it through the abdomen during removal of the inflation assembly.By not cutting the inflation tube the yellow anchor would be left on the inflation tube during removal, and would most likely get caught behind the mesh or possibly on the trocar during removal.Based on the event as reported, the sample evaluation and the investigation activities performed the anchor detached from forces applied during the removal process as the surgeon would have had to apply excess force to remove the inflation tube with the yellow anchor still present.The instructions-for-use instruct the user to cut the inflation tube as close to the skin as possible prior to removal.Had the user done this the yellow anchor portion of the inflation tube would have been removed prior to pulling it through the abdomen.The sample evaluation confirms detachment of the yellow anchor form the inflation tube.A review of the manufacturing records was performed and found that the lot was manufactured to specification.No manufacturing issues associated to the reported event were found in the reviewed lot.
