Abstract

The present invention relates to devices and methods for treating fractured and/or diseased bone. More specifically, the present invention relates to devices and methods for repairing, reinforcing and/or treating fractured and/or diseased bone using various devices, including cavity-forming devices.

Claims

1. A method for restoring an intraosseous space comprising:

(a) accessing said space;

(b) placing in said space a first aliquot of restorative composition; and

(c) after a period of time sufficient for said first aliquot to set, placing in said space a second aliquot of restorative composition.

2. The method of claim 1 wherein the placement of said first aliquot is preselected so as to initiate restorative process.

3. The method of claim 1 wherein said pre-selection is of the location of said placement and said placement isolates said intraosseous space from surrounding tissue.

4. The method of claim 1 further comprising placing additional aliquots of restorative composition in said space.

5. The method of claim 1 wherein the further placements follow preselected time intervals.

6. The method of claim 1 wherein the further placements are of a preselected amount.

7. The method of claim 1 wherein said placement is via a syringe.

8. The method of claim 1 wherein said placement is via a catheter or cannula.

9. The method of claim 8 wherein the location of the catheter or cannula in the intraosseous space is monitored.

10. The method of claim 9 wherein the monitoring is via fluoroscopy.

11. The method of claim 9 wherein the monitoring is via endoscopy.

12. The method of claim 8 wherein the catheter has a distal end and at least one placement orifice disposed proximate to said distal end, said placement orifice being adapted for dispensing the restorative composition radially from the catheter.

13. The method of claim 1 wherein said space is accessed via a drill or micro-reamer.

14. The method of claim 1 wherein said space is accessed via a knife or sharp instrument.

15. The method of claim 1 wherein said space is accessed via a needle or cannula.

16. The method of claim 9 wherein the monitoring is via visualization

17. The method of claim 1 wherein said space is accessed via an instrument having a sharp end.

18. The method of claim 8 wherein the catheter has a distal end adapted for dispensing the restorative composition from the catheter.

19. The method of claim 1 wherein said placement is via use of a plunger.
