An altis sling was returned for evaluation.Examination of the sling revealed the static anchor and suture were detached and not returned.Visual observation of the mesh where the static suture was attached confirmed the welded area of the suture was still attached.Microscopic examination of the mesh where the static anchor was attached revealed rough and irregular surfaces, indicating stress may have been exerted.The dynamic anchor and suture were still attached.Blood residue was noted on the mesh.The information received indicated the static anchor detached during the procedure.Quality confirmed the detached static anchor.As the static anchor and suture were not received, it was concluded that the detachment of the static anchor most likely occurred while placing the anchor through the obturator membrane.As the detachment ends of the static suture were rough and irregular, this indicated that excess stress was most likely exerted to result in the separation noted.A review of the device history record by the contract manufacturer confirmed the devices from this lot met all specifications prior to release.A review of the complaint history database, nonconformances and capas revealed no trends for this lot.
