Abstract

An improved sternal closure device and method for using the device is disclosed wherein a pair of thin rods of appropriate length are positioned longitudinally along respective opposite sides of a severed sternum on the posterior surface thereof. Individual wires secured at one end thereof to corresponding points along each rod are passed through matching holes on either side of the severed sternum to extend beyond its anterior surface. Opposing pairs of wires transversely oriented are tensioned to draw the sternum together and knotted thereby holding the sternum closed with forces applied by the wires and distributed along the length of the sternum via the rods. Alternatively, the wires may have looped inner ends that engage the rods on the posterior surface of the sternum for distribution of the closing forces.

Independent Claims | See all claims (5)

  1. 1. A device for closing a severed sternum, comprising:a pair of rods each to be disposed longitudinally along respective separate sides of the sternum immediately adjacent to the posterior surface thereof; anda plurality of wires each connected at one end thereof to corresponding points along each of said rods, said wires to be extended through the respective separate sides of the sternum and be connected at their other ends in opposing pairs on the anterior surface of the sternum.
  2. 4. A method for closing a severed sternum with a pair of rods and a plurality of wires each connected at one end thereof to corresponding points along each rod, comprising the steps of:providing a matching series of holes through opposite sides of the severed sternum;inserting the wires through the holes from the posterior surface of the sternum until the rods are disposed along the opposite sides of the sternum immediately adjacent to the posterior surface thereof;tensioning the wires to draw the severed sternum together; and twisted together opposing pairs of the wires on the anterior surface of the sternum.
  3. 5.5. A method for closing a severed sternum with a pair of rods and a plurality of wires each terminated at one end thereof with a closed loop, comprising the steps of:providing a matching series of holes through opposite sides of the severed sternum;passing each wire through a respective one of the holes from the posterior surface of the sternum;inserting the rods through the looped ends of the wires on respective opposite sides of the sternum adjacent to the posterior surface thereof;tensioning the wires to draw the severed sternum together; and twisted together opposing pairs of the wires on the anterior surface of the sternum.
