Abstract

A flexible implant system includes a flexible implant, an implant housing, and an implant set screw. The flexible implant is configured to loop around a portion of a bony element. The implant housing includes a housing body defining a rod passage configured to receive a rod. The housing body also defines an implant passage that receives a portion of the flexible implant. The implant set screw engages the flexible implant within the implant passage to fix the flexible implant to the implant housing.

First claim

What is claimed:

1. An implant comprising:
a first securement member configured to secure the implant to a rod;
a second securement member; and
a housing of unitary construction having a first opening configured to receive the first securement member and a second opening configured to receive the second securement member, the first and second openings parallel to and offset from one another along a longitudinal axis of the housing, the second securement member configured to secure a portion of a flexible member within the housing, wherein the housing defines a member passage in communication with the second opening configured to receive the flexible member in an orientation transverse to the rod.

2. The implant according to claim 1 , wherein the first securement member is configured to directly engage a rod to secure the implant to the rod.

3. The implant according to claim 1 , wherein the housing defines a rod passage in communication with and extending in a direction orthogonal to the longitudinal axis of the housing.

4. The implant according to claim 1 , wherein the member passage extending in a direction parallel to the longitudinal axis of the housing.

5. The implant according to claim 1 , further comprising a chock secured to the second securement member, the chock configured to directly engage the flexible member to secure the implant to the flexible member.

6. The implant according to claim 1 , wherein the first securement member is a set screw threadably secured within the first opening of the housing.

7. The implant according to claim 1 , wherein the second securement member is a set screw threadably secured within the second opening of the housing.

8. An implant system comprising:
a flexible member having a first portion, a second portion, and a central portion disposed between the first and second portions, the flexible member configured to pass around a bony element;
a housing of unitary construction having a first opening and a second opening parallel to and offset from one another along a longitudinal axis of the housing;
a first securement member received within the first opening and configured to secure the housing to a rod; and
a second securement member received in the second opening to selectively secure the first and second portions of the flexible member within the housing, wherein the housing defines a member passage in communication with the second opening configured to receive the flexible member in an orientation transverse to the rod.

9. The implant system according to claim 8 , further comprising a tensioning instrument configured to secure to the housing and to draw the flexible member through the housing to tension the flexible member about a bony element.

10. The implant system according to claim 9 , wherein the tensioning instrument is configured to provide access to the second securement member while the flexible member is tensioned by the tensioning instrument about a bony element.

11. The implant system according to claim 8 , wherein the first securement member is configured to directly engage a rod to secure the implant to the rod.

12. The implant system according to claim 8 , wherein the housing defines a rod passage in communication with and extending in a direction orthogonal to the longitudinal axis of the housing.

13. The implant system according to claim 8 , wherein the member passage extending in a direction parallel to the longitudinal axis of the housing.

14. The implant system according to claim 8 , wherein the second securement member is configured to directly engage the first and second portions of the flexible member to secure the implant to the flexible member.

15. The implant system according to claim 8 , further comprising a chock secured to the second securement member, the chock configured to directly engage the first and second portions of the flexible member to secure the implant to the flexible member.

16. An implant system comprising:
a flexible member having a first portion, a second portion, and a central portion disposed between the first and second portions, the flexible member configured to pass around a bony element;
a housing of unitary construction having a first opening and a second opening parallel to and offset from one another along a longitudinal axis of the housing;
a first securement member received within the first opening and configured to secure the housing to a rod;
a second securement member received in the second opening to selectively secure the housing to the flexible member, the second securement member including a threaded portion and an engagement portion extending from the threaded portion, the engagement portion defining a recess configured to secure the chock to the second securement member; and
a chock secured to the second securement member, the chock configured to directly engage the first and second portions of the flexible member to secure the implant to the flexible member.

17. The implant system according to claim 16 , wherein the recess receives a portion of the chock to secure the chock to the second securement member.

18. The implant system according to claim 16 , wherein the recess receives a chock pin to secure the chock to the second securement member.
