Abstract

A fixation assembly for securing parts of a sternum is provided. The assembly comprises a flexible elongated member and an attachment member. The flexible elongated member includes a locking structure configured to secure the flexible elongated member in a loop around the sternum parts. The attachment member has at least one opening for receiving a bone fastener and is coupled to the flexible elongated member.

First claim

The invention claimed is:

1. A fixation assembly for securing parts of a sternum, the assembly comprising:
a flexible elongated member including a locking structure configured to secure the flexible elongated member in a loop around the sternum parts; and
an attachment member coupled to the flexible elongated member and having at least one opening for receiving a bone fastener, wherein the at least one opening includes a locking feature having a threaded portion or a lip extending in a circumferential direction for engaging a bone fastener.

2. The fixation assembly according to claim 1 , wherein each of the flexible elongated member and the attachment member defines a width in a transverse direction thereof, wherein the width of the attachment member is larger than or substantially equal to the width of the flexible elongated member.

3. The fixation assembly according to claim 1 , wherein each of the flexible elongated member and the attachment member has a thickness, wherein the thickness of the attachment member is larger than or substantially equal to the thickness of the flexible elongated member.

4. The fixation assembly according to claim 1 , wherein the locking structure of the flexible elongated member includes a latching mechanism configured to lock the flexible elongated member in a loop configuration.

5. The fixation assembly according to claim 4 , wherein the flexible elongated member includes teeth, barbs or claws arranged along a longitudinal direction of the flexible elongated member and lockable with the latching mechanism.

6. The fixation assembly according to claim 1 , wherein the flexible elongated member and the attachment member are integrally formed.

7. The fixation assembly according to claim 1 , wherein the attachment member is formed as a bone plate.

8. The fixation assembly according to claim 1 , wherein the attachment member includes at least one bridge configured to be cut with a surgical tool, wherein the at least one bridge is configured to connect first and second sections of the attachment member to each other.

9. The fixation assembly according to claims 1 , further comprising: a further attachment member formed as a bone plate including at least one opening for receiving a bone fastener.

10. A fixation assembly for securing parts of a sternum, the assembly comprising:
a flexible elongated member including a locking structure configured to secure the flexible elongated member in a loop around the sternum parts; and
an attachment member having central and lateral portions, the lateral portion having at least one opening for receiving a bone fastener, wherein the at least one opening has a conical convex or spherical taper which substantially tapers inwardly in a direction toward a bone contacting surface of the attachment member.

11. A fixation assembly for securing parts of a sternum, the assembly comprising:
a flexible elongated member including a locking structure configured to secure the flexible elongated member in a loop around the sternum parts; and
an attachment member having a central portion and a lateral portion extending outwardly from the central portion, the attachment member including at least one opening having an inclined surface on which a bone fastener is able to slide into a fastening or compression position.
