Abstract

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

First claim

The following is claimed:

1. A method of utilizing a bondable material to position a fastening implant in a body, said method comprising:
engaging an end effector and at least a trailing end of the fastening implant;
passing at least a portion of the end effector and the fastening implant into the body;
positioning at least a leading end surface of the fastening implant in contact with the bondable material, such that the leading end surface directly contacts the surface of the bondable material, wherein the bondable material is fixed inside the body;
applying vibratory energy to at least the trailing end of the fastening implant, thereby transmitting vibratory energy to the leading end of the fastener to soften at least a portion of the bondable material in contact with the leading end surface, such that the bondable material mechanically interlocks with at least a portion of the leading end of the fastening implant when the bondable material is solidified; and
disengaging the end effector from the trailing end of the fastening implant.

2. The method of claim 1 wherein the bondable material is at least one of polymethyl methacrylate (PMMA), polyaryletherketone (PAEK), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), and Poly-l-lactide (PLLA).

3. The method of claim 1 wherein at least a portion of the fastening implant is bonded into the bondable material.

4. The method of claim 1 wherein the bondable material is substantially hard before application of energy.

5. The method of claim 1 wherein at least a portion of the bondable material flows into the fastening implant to secure the at least a portion of the fastening implant to the bondable material.

6. The method of claim 1 wherein disengaging the end effector from the trailing end of the fastening implant includes rotationally disengaging the end effector from the fastening implant.

7. The method of claim 1 wherein the fastening implant includes at least a portion of titanium.

8. The method of claim 1 wherein the fastening implant includes at least a portion of at least one of stainless steel, nitinol, tantalum, porous tantalum, titanium, cobalt-chrome alloy, polyaryletherketone (PAEK), poly etheretherketone (PEEK), polyetherketoneketone (PEKK), and Poly-l-lactide (PLLA).

9. The method of claim 1 wherein the fastening implant includes at least a portion of titanium and at least a portion of a polymer.

10. The method of claim 1 wherein applying vibratory energy includes applying ultrasonic energy.

11. The method of claim 1 wherein the fastening implant stabilizes a bone of a body by embedding in a previously hardened bondable material adjacent to the bone.

12. The method of claim 1 wherein disengaging the end effector from the trailing end of the fastening implant includes disengaging the end effector from the fastening implant when the bondable material solidifies and mechanically interlocks with the fastening implant.

13. A method of utilizing a bondable material adjacent a tissue in a body, said method comprising:
passing an embedding implant and at least a portion of an end effector into the body;
positioning at least a leading end surface of the embedding implant in contact with the bondable material, such that the leading end surface directly contacts the surface of the bondable material, wherein the bondable material is fixed inside the body;
applying vibratory energy to the embedding implant to embed the embedding implant into at least a portion of the bondable material; and
engaging a fastening implant with the embedding implant to remain in the body to secure the tissue.

14. The method of claim 13 wherein embedding the embedding implant into at least a portion of the bondable material includes bonding the embedding implant to the bondable material.

15. The method of claim 13 wherein the bondable material is at least one of polymethyl methacrylate (PMMA), polyaryletherketone (PAEK), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), and Poly-l-lactide (PLLA).

16. The method of claim 13 wherein applying vibratory energy includes applying ultrasonic energy.

17. The method of claim 13 wherein the bondable material has previously polymerized before positioning the embedding implant.

18. The method of claim 13 wherein applying vibratory energy includes applying vibratory energy to enable the bondable material to flow around the fastening implant.

19. The method of claim 13 wherein applying vibratory energy includes applying vibratory energy to enable the bondable material to flow into the fastening implant.

20. A method of utilizing a bondable material adjacent a tissue in a body, said method comprising:
engaging an embedding implant and an end effector;
passing the embedding implant and at least a portion of the end effector into the body;
positioning at least a leading end surface of the embedding implant in contact with the bondable material, such that the leading end surface directly contacts the surface of the bondable material, wherein the bondable material is fixed inside the body;
applying vibratory energy to the embedding implant to embed the embedding implant into at least a portion of the bondable material;
positioning a supporting implant adjacent the tissue; and
engaging a fastening implant with the embedding implant to remain in the body to secure the supporting implant adjacent the tissue.

21. The method of claim 20 wherein the embedding implant is bonded to the bondable material.

22. The method of claim 20 wherein the bondable material is at least one of polymethyl methacrylate (PMMA), polyaryletherketone (PAEK), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), and Poly-l-lactide (PLLA).

23. The method of claim 20 wherein vibratory energy includes ultrasonic energy.

24. The method of claim 20 wherein the bondable material has previously polymerized before positioning the embedding implant.

25. The method of claim 20 wherein bondable material flows around the fastening implant during application of vibratory energy.

26. The method of claim 20 wherein the bondable material flows into the fastening implant during application of vibratory energy.

27. The method of claim 20 wherein the supporting implant includes a plate.

28. The method of claim 20 wherein the tissue includes a bone of the body.
