  • Patent number: 10188495
    Abstract: A non-setting agent for positioning a surgical mesh prosthesis against a tissue defect during surgical hernia repair enables a surgeon to position the surgical mesh prosthesis at an optimal location against the tissue defect without pre-measuring suture location and pre-suturing. The surgical mesh prosthesis can be repositioned by removing and replacing, or by sliding, the mesh along the tissue defect without traumatizing the tissue. The positioning agent is provided with adhesion and lubricity characteristics providing an adhesion strength required to temporarily maintain the surgical mesh in place, otherwise unsupported, against tissue of a targeted tissue location, and providing a viscosity that permits removal and replacement, or slidable movement, of the surgical mesh along the tissue upon receipt of a non-gravitational external force applied to the surgical mesh so movement of the surgical mesh that is atraumatic to the tissue.
