Abstract

An implant for a human rib can include an elongate body, a plurality of bores, and a placement tool interface. The elongate body can include a first portion including a flat outer face where the elongate body can be curved along a plane perpendicular to the flat outer face. The second portion can extend from the first portion to form a curved outer face. The plurality of bores can extend through the flat outer face of the first portion and into the second portion. The bores can extend partially into the curved outer face of the second portion. The placement tool interface can extend into the body.

First claim

The invention claimed is:

1. A method of securing an implant to a rib bone, the method comprising:
attaching a drill guide to a placement tool;
rotating the drill guide to substantially align with arms of the placement tool;
inserting the drill guide and the placement tool into a thoracic cavity through a thoracic opening;
pivoting the drill guide to align with a posterior portion of a rib; and
guiding a drill bit through a drill guide bore of the drill guide to the posterior portion of the rib.

2. The method of claim 1 , further comprising:
drilling a rib bore in the rib using the drill guide bore as a guide.

3. The method of claim 2 , further comprising:
pivoting the drill guide to substantially align with arms of the placement tool while the drill guide is within the thoracic cavity; and
removing the drill guide and the placement tool from the thoracic cavity.

4. The method of claim 3 , further comprising:
detaching the drill guide from the placement tool; and
attaching the implant to the placement tool.

5. The method of claim 4 , further comprising:
pivoting the implant to substantially align with the arms of the placement tool; and
inserting the implant and the placement tool into the thoracic cavity.

6. The method of claim 5 , further comprising:
aligning a bore of the implant with the rib bore; and
inserting a fastener through an anterior side of the rib bore and into the bore of the implant.

7. The method of claim 6 , wherein inserting the fastener comprises:
threading a distal portion of the fastener into the bore of the implant; and
threading a medial portion of the fastener into the rib bore;
wherein the distal portion of the fastener has a first thread type and the medial portion has a second thread type that is different from the first thread type.

8. The method of claim 6 , further comprising:
detaching the implant from the placement tool while the implant is within the thoracic cavity; and
removing the placement tool from the thoracic cavity.

9. A method of securing an implant to a rib bone, the method comprising:
inserting a pin of a placement tool into a bore of a drill guide to attach the drill guide to the placement tool;
pivoting the drill guide about the pin to substantially align with one or more aims of the placement tool;
inserting the drill guide and the placement tool into a thoracic cavity through a thoracic opening;
pivoting the drill guide about the pin to align with a posterior portion of a rib;
guiding a drill bit to the posterior portion of the rib using a drill guide bore of the drill guide;
drilling a rib bore using the drill guide bore as a guide;
pivoting the drill guide to substantially align with the one or more arms of the placement tool while the drill guide is within the thoracic cavity; and
removing the drill guide and the placement tool from the thoracic cavity.

10. The method of claim 9 , further comprising:
detaching the drill guide from the placement tool; and
attaching the implant to the placement tool.

11. The method of claim 10 , further comprising:
pivoting the implant to substantially align with the one or more arms of the placement tool; and
inserting the implant and the placement tool into the thoracic cavity through the thoracic opening.

12. The method of claim 11 , further comprising:
aligning a bore of the implant with the rib bore; and
inserting a fastener through an anterior side of the rib bore and into the bore of the implant.

13. The method of claim 12 , further comprising:
detaching the implant from the placement tool while the implant is within the thoracic cavity; and
removing the placement tool from the thoracic cavity.

14. A method of securing an implant to a rib bone, the method comprising:
attaching a drill guide to a placement tool;
pivoting the drill guide to align with one or more arms of the placement tool;
inserting the drill guide and the placement tool into a thoracic cavity;
pivoting the drill guide to align with a posterior portion of a rib;
guiding a drill bit to the posterior portion of the rib using a drill guide bore of the drill guide; and
drilling a rib bore in the rib using the drill guide bore as a guide.

15. The method of claim 14 , further comprising:
pivoting the drill guide to substantially align with the one or more arms of the placement tool while the drill guide is within the thoracic cavity;
removing the drill guide and the placement tool from the thoracic cavity; and
detaching the drill guide from the placement tool.

16. The method of claim 15 , further comprising:
attaching the implant to the placement tool;
pivoting the implant to substantially align with the one or more arms of the placement tool; and
inserting the implant and the placement tool into the thoracic cavity.

17. The method of claim 16 , further comprising:
aligning a bore of the implant with the rib bore; and
inserting a fastener through an anterior side of the rib bore and into the bore of the implant.

18. The method of claim 16 , wherein the implant includes an elongate body comprising:
a first portion and a second portion opposite the first portion;
an implant bore extending through the first portion and partially into he second portion; and
a placement tool interface extending into the elongate body.

19. The method of claim 18 , wherein the placement tool includes:
a handle;
a first arm extending from the handle; and
a second arm extending from the handle with the first arm.

20. The method of claim 19 , wherein the placement tool includes a retaining pin extending from a distal portion of the first arm, the retaining pin engageable with the placement tool interface to form a pivotable engagement therewith to allow the implant to rotate about the retaining pin between an orientation perpendicular to the first arm and the second arm and an orientation parallel to and between the first arm and the second arm.
