  • Patent number: 10842603
    Abstract: A sutureless ventral hernia meshing system and method of fixation is efficacious for fixating a surgical mesh panel to an abdominal wall for the purpose of hernia repair and prevention of hernia recurrence at the peripheral region of the mesh panel. The mesh panel comprises a hydrophilic face and a meshed face. A plurality of hollow anchors such as spikes or pins or hooks are disposed along the peripheral region of the mesh panel in a spaced apart relationship. A blunt quill or needle presses the hollow spikes or pins or hooks into the fascia around the hernia. The blunt quill or needle is removed after pressing the hollow pin into the fascia. In this manner, no sharp needle or suture is used. Tissue growth occurs in the cavity of the hollow spikes or pins or hooks to provide a sutureless anchor.
