Sternum closure device having locking member
First Claim
1. A sternum closure device for positioning between at least two corresponding rib pairs substantially surrounding a patients sternum, the sternum closure device comprising:
- a sliding attachment structure including;
a plurality of projection members with angularly disposed teeth-like structures inwardly positioned on the innermost edges of each the plurality of projection members; and
first and second leg portions, each of the first and second leg portions including a sliding attachment structure associated integrated foot portion and a sliding attachment structure associated sternum engagement portion;
a receiving attachment structure including;
a securing aperture; and
third and forth leg portions, each of the third and fourth leg portions including a receiving attachment structure associated integrated foot portion and a receiving attachment structure associated sternum engagement portion; and
a generally bow-shaped locking member attached to the securing aperture of the receiving attachment structure and including a first distal end and a second distal end, each of the first distal end and the second distal end including angularly disposed teeth-like structures; and
wherein the generally bow-shaped locking member is resiliently tensioned between the plurality of projection members such that the angularly disposed teeth-like structures of the generally bow-shaped locking member engage the angularly disposed teeth-like structures of the plurality of projection members.

Abstract
A sternal closure device including impermanently joined sliding and receiving attachment structures which are adapted for intercostal positioning between at least two corresponding rib pairs and substantially surrounding a patient'"'"'s sternum with each structure having a cross member, a plurality of integrated legs and foot members, a plurality of sternum engagement surfaces, and an end portion. The receiving structure further incorporates a generally bow-shaped locking member with angularly disposed teeth-like structures positioned to receive and position a plurality of receiving structure projection members when inserted therein. The locking member further serves as a stabilizing structure with stabilization facilitated via an easily removed single screw like structure markedly facilitates quick release. The projection members further embody complimenting positioned teeth-like structures providing for racheting, unidirectional entry and positioning within the receiving attachment structure.
