A batch review of the finished good lot and components confirmed there were no quality issues noted throughout the incoming inspection, manufacturing, sterilization, in-process, or final inspection process.Sterile samples were not available for testing / review.Retained samples were not available for review.No photos of the surgical site were provided for review, if samples, photos or additional information become available at a later date, the samples, photos or information will be reviewed and results will added to the file, a revised response will be forwarded to you at that time.The suture breaking during use most likely resulted from the interaction of specific procedural related stress in contrast to the suture strength.It''s also possible the devices are being grasped with surgical instruments damaging the suture allowing the suture to break during use.The ¿precautions¿ section in the ifu for the device states ¿the stratafix¿ pdo device contains a loop end and barbs to anchor tissues and does not require knots to approximate opposing edges of a wound.Tying of knots on the barbed section of the material will damage the barbs and potentially reduce their effectiveness.For the device to function properly, the stratafix¿ spiral pdo device must first be anchored in the tissue by the deployment of the loop around robust tissue, then with the other subsequently engaged in the tissue by the barbs.Additionally, when completing placement of the barbed segment, an additional backstitch or bite of tissue lateral to the end of the incision is required to lock the stratafix¿ spiral pdo device in place.Care should be taken to avoid damage when handling.Avoid crushing or crimping the suture material with surgical instruments such as needle holder and forceps¿.Without receiving sterile devices from this same lot to review/test or receiving detailed information regarding the pre-operative preparation of the devices, tools utilized to grasp the devices, the method utilized to anchor the device in the tissue, the patient¿s health status and quality of the tissue, or the surgeon¿s experience and/or technique, a definitive root cause for the reported event cannot be confirmed with certainty.
