Abstract

In a sternum closure device for securing two sternum parts to be connected to one another, comprising an inner contact element to abut the inner face of the sternum, at least one clamping element secured thereto and projecting transversely therefrom, and comprising an outer contact element for abutment on the outer side of the sternum and which can be clamped by means of the clamping element guided through the intermediate space between the sternum parts against the inner contact element, in order to reduce the obstruction by the sternum closure device in the event of a renewed separation of the sternum parts, it is proposed that the inner contact element consists at least partially of a biocompatible plastics material.

Claims

1. Sternum closure device for securing two sternum parts to be connected to one another, comprising an inner contact element to abut the inner face of the sternum, at least one clamping element secured thereto and projecting transversely therefrom, and comprising an outer contact element for abutment on the outer side of the sternum and which can be clamped by means of the clamping element guided through the intermediate space between the sternum parts against the first contact element, the inner contact element consisting at least partially of a biocompatible plastics material, wherein the inner contact element has a centre part made of plastics material and holding projections connected thereto to secure the inner contact element on the sternum and wherein the holding projections are connected to one another by means of a strip-like web, which consists of metal and is embedded in the plastics material.

2. Sternum closure device according to claim 1, wherein the plastics material is polyether ether ketone.

3. Sternum closure device according to claim 1, wherein the plastics material is a resorbable plastics material.

4. Sternum closure device according to claim 1, wherein the holding projections are arranged in two rows extending on opposing sides of the centre part.

5. Sternum closure device according to claim 1, wherein the projections are embedded in the plastics material.

6. Sternum closure device according to claim 1, wherein the web has through openings, through which the plastics material passes.
