The OnFlex™ Mesh is indicated for use in the reinforcement of soft tissue where weakness exists, such as in the repair of inguinal hernias.


Do not use this mesh in infants, children, or pregnant women, whereby future growth may be compromised by the use of such mesh material. The use of this mesh has not been studied in breastfeeding or pregnant women. Literature reports there may be a possibility for adhesion formation when the polypropylene is placed in contact with the bowel or viscera.

Adverse Reactions

Possible complications may include, but are not limited to, seroma, adhesion, hematoma, pain, infection, inflammation, extrusion, erosion, migration, fistula formation, allergic reaction, and recurrence of the hernia or soft tissue defect. The mesh must be removed immediately if the SorbaFlex™ PDO monofilament is cut or damaged during insertion of fixation. If the SorbaFlex™ PDO monofilament is cut or damaged, additional complications may include, but are not limited to, bowel or skin perforation and infection.


  1. The use of any synthetic mesh or patch in a contaminated or infected wound can lead to fistula formation and/or extrusion of the mesh and is not recommended.
  2. If an infection develops, treat the infection aggressively. Consideration should be given regarding the need to remove the mesh. Unresolved infection may require removal of the mesh.
  3. Do not cut or reshape the Onflex™ Mesh, except at the opening in the interrupted SorbaFlex™ PDO monofilament, to accommodate the spermatic cord and outside of the blue limit line in the lateral portion of the mesh, as this could affect its effectiveness. Care should be taken not to cut or nick the SorbaFlex™ PDO monofilament.
