Abstract

An implant for bone fixation is presented. The implant comprises an elongated member configured to be wound around bone parts that are to be fixed. Further, an engagement feature is provided that is coupled to the elongated member and configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone parts. A fastening member is arranged between and coupled to the elongated member and the engagement member. The fastening member comprises at least one opening for receiving a bone fastener. In one variant, at least one visual indicator indicating a region of the fastening member to be severed in order to detach the implant is provided. In another variant, at least one of the engagement member and the elongated member are coupled to the fastening member by injection molding.

First claim

The invention claimed is:

1. An implant for bone fixation, comprising:
an elongated member configured to be wound around bone parts that are to be fixed;
an engagement member configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone parts; and
a fastening member comprising at least one opening for receiving a bone fastener, wherein the fastening member is coupled to at least one of the elongated member and the engagement member by injection molding.

2. The implant of claim 1 , wherein the fastening member is coupled to the elongated member, the engagement member is coupled to the fastening member and the elongated member when the implant is secured in the loop around the bone parts.

3. The implant of claim 1 , wherein the elongated member defines a first end and a second end, the fastening member is coupled to the second end of the elongated member, and the engagement member is spaced apart from the second end of the elongated member and is configured to engage a portion of the elongated member located between the first and second ends so as to secure the implant in the loop around the bone parts.

4. The implant of claim 1 , wherein the elongated member comprises a plurality of engagement features provided along an extension of the elongated member, wherein the engagement member is configured to be brought into selective engagement with one of the engagement features.

5. The implant of claim 1 , further comprising a hook member coupled to the elongated member at an end thereof opposite to the engagement member.

6. The implant of claim 5 , wherein the hook member is coupled to the elongated member by injection molding.

7. The implant of claim 1 , wherein the at least one opening of the fastening member comprises a locking feature configured to lock the bone fastener to the fastening member.

8. The implant of claim 1 , wherein the fastening member is made from a metallic material and the elongate member is made from a polymeric material.

9. An implant system, comprising:
an implant for bone fixation, comprising:
an elongated member configured to be wound around bone parts that are to be fixed;
an engagement member configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone parts; and
a fastening member comprising at least one opening for receiving a bone fastener, the fastening member being coupled to at least one of the elongated member and the engagement member by injection molding; and
at least one bone fastener configured to be inserted through the at least one opening of the fastening member and into bone.

10. The implant system of claim 9 , wherein the fastening member is coupled to the elongated member, the engagement member is coupled to the fastening member and the elongated member when the implant is secured in the loop around the bone parts.

11. The implant system of claim 9 , wherein the elongated member defines a first end and a second end, the fastening member is coupled to the second end of the elongated member, and the engagement member is spaced apart from the second end of the elongated member and is configured to engage a portion of the elongated member located between the first and second ends so as to secure the implant in a loop around the bone parts.

12. The implant system of claim 9 , wherein the at least one opening comprises a first locking feature configured to lock the bone fastener to the fastening member and wherein the bone fastener comprises a second locking feature configured to engage the first locking feature.

13. A method of manufacturing an implant, comprising:
obtaining an elongated member configured to be wound around bone parts that are to be fixed;
obtaining an engagement member configured to engage a portion of the elongated member so as to secure the implant in a loop around the bone parts; and
coupling a fastening member having at least one opening for receiving a bone fastener to at least one of the elongated member and the engagement member via injection molding to form the implant.

14. The method of claim 13 , wherein the fastening member is coupled to the elongated member, the engagement member is coupled to the fastening member and the elongated member when the implant is secured in the loop around the bone parts.

15. The method of claim 13 , wherein the elongated member defines a first end and a second end, the fastening member is coupled to the second end of the elongated member, and the engagement member is spaced apart from the second end of the elongated member and is configured to engage a portion of the elongated member located between the first and second ends so as to secure the implant in the loop around the bone parts.
