Abstract
Percutaneous suture externalizer devices are disclosed which grasp, secure and externalize sutures from within an abdominal or thoracic cavity. The suture externalizer devices include a thin tubular sheath with a penetrating point and a hook rod slidable within the sheath. The hook rod is slidable between an extended position and a retracted position. The hook rod is biased to the extended position. In the retracted position, a suture grasped within the hook is snugly held between the hook rod and the inner wall of the sheath, providing a positive means of securing the suture during externalization. An alternative embodiment utilizes a hollow tubular hook rod that can also be used to insufflate the abdominal or thoracic cavity. The alternative embodiment utilizes a valve to control the flow of gas through the hook rod, into and out of the cavity.
