  • Patent number: 11576705
    Abstract: An internal intramedullary fixation device for the stabilization of bone in arthrodesis and fractures of the foot and hand is disclosed. During implantation in medullary canals of bones, the device grasps the edges of the canals, stabilizing the bones, internally, during a healing process. The intramedullary fixation device comprises arrow-shaped proximal and distal heads comprising tips and a pairs of wings, the heads being sized to fit within an intramedullary canal of a bone. The intramedullary fixation device also comprises a rigid body defining a longitudinal axis connecting the proximal and distal heads. The rigid body comprises an intermediate portion, a distal neck portion connecting the rigid body to the distal head, and a proximal neck portion connecting the rigid body to the proximal head, the neck portions having a cross-sectional area smaller than a cross-section area of the intermediate portion.

  • Patent number: 9974580
    Abstract: An intramedullary fixation device used in bone fixation and stabilization on a patient includes a longitudinally extending rigid body and a distal head disposed at a distal end of the body. The distal head includes a central core portion and a plurality of extending distal wings radially projecting from the central core portion, wherein the radially projecting distal wings are spaced asymmetrically about the central core portion. A proximal head at a proximal end of the body and sized for insertion into an intramedullary canal of a phalanx of the patient. The proximal head includes a central core portion and a plurality of proximal wings extending radially outwardly from the central core portion.
