Evaluation summary: the device was not returned for investigation however pictures were provided.The visual examination of the provided pictures shows a mesh in vivo with a similar knitting pattern than symbotex meshes.3 pictures are provided showing parts of the mesh fixed with absorbable tacks.A hole of around 2 stitches seems to be visible in the picture 2.On the pictures 2 and 3 tacks are placed at respectively 2 and 4 stitches from the edge.However due to the picture quality, it is not possible to determine how many holes were formed, where exactly they are located in the mesh, if it is a tear or a cut, and if the mesh have been overstretched or not.Without the sample a detailed investigation could not be performed.A review of the device history record has been performed and no failure or ncr that may relate to the reported conditions have been noted.It should be noted that the mesh was fixed with over 30 absorbable tacks and 8 transfacial sutures.The product ifu which accompanies each device of symbotex¿ composite mesh states in chapter ¿warnings¿ that ¿2.In order to maintain the elasticity and the porosity of the reinforcement, it is recommended that the mesh should not be overly stretched when it is being put in place.A moderate and equal tension should be applied in all directions for fixation in order to account for wound shrinkage during the healing process.¿ and in chapter ¿operating steps ¿ positioning¿ that ¿5.The edge of the reinforcement should be at least 5 cm over the edges of the defect(s).The technique used to anchor the mesh (suture or staples) is left up to the practitioner.It is suggested to fixate the mesh at a distance approximately 1 cm from the edge of the mesh.¿ the reported information is too limited to determine the root cause or most probable cause of the reported incident and/or to determine if the incident is associated with a manufacturing or component discrepancy.Based on the available information, our investigation and a complaint history review, it is not possible to determine if the manufacture of the device is suspected or not.There is no indication that there is a defective lot or that this event represents an emerging adverse quality trend.If information is provided in the future, a supplemental report will be issued.
