  • Implantable biodegradable wound closure device and method
    Patent number: 9011485
    Abstract: An implantable biodegradable device consisting of an inner button attached to a cylindrical segment, and an outer button attached to a retainment feature. The cylindrical segment is threaded on one end, with a surface groove. The retainment feature consists of radial strips with bent ends. The diameter of the radial strips is slightly larger than the outer diameter of the cylinder. The bent ends fit into the groove. An insertion tool can attach to the threads in the cylinder and push the inner button through a wound, then, holding the inner button in place, push the outer button toward the inner button until the bent ends engage with the groove. The top of the threaded end of the cylindrical segment is adjacent to the back surface of the outer button when the bent ends of the retainment feature are engaged with the groove.
