Abstract

A surgical device and method are disclosed for closing the sternum following a median sternotomy. Instead of using stainless steel wire or a flat steel band, a strand of thin flexible suture material is used which is compressible in its radial dimension (either because of a hollow tubular shape, or due to solid material properties), while remaining strong and inelastic in its longitudinal dimension. The longitudinal strength may be maintained by using selected plastics, or by using nylon fibers or other materials for reinforcement. When not compressed, the strand has a diameter slightly larger than the diameter of the needle used to place the strand in position around the sternal halves, between the ribs. After insertion, the expandable suture material will provide gentle pressure against the surrounding tissue to minimize bleeding in the needle track. The soft suture material will also help cushion, distribute, and minimize the stresses and damage inflicted on the sternum or ribs during postoperative ambulation. A fastener device which provides additional advantages is also disclosed.
