Abstract

Novel kits are provided for the delivery of restorative compositions into an intraosseous space or surgical defect comprising cannulae for accessing an intraosseous space, mandarins insertable into the cannulae and movable therein, catheters and a system for the delivery of aliquots of restorative compositions into the space via the catheters.

Claims

1. A kit for delivery of a restorative composition to an intraosseous space, comprising:

a plurality of stainless steel catheters having graded markings on an external surface thereof,

a plurality of syringes of different volumes,

and a plunger,

wherein the internal diameters of each of the plurality of syringes are equal and the plunger has a diameter allowing it to move within the barrel of each interchangeably.

2. The kit of claim 1 wherein said 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.

3. The kit of claim 1 further comprising a cannula with a solid handle affixed to a proximate portion of said cannula and has asymmetric halves extending outward from a bore along the axis of the cannula.

4. The kit of claim 1 further comprising a micro-reamer.

5. The kit of claim 1 further comprising a screw having a bore along the longitudinal axis of said screw.

6. The kit of claim 1 further comprising a stylet, micro-reamer, and cannula having a proximate end and distal end and a lateral surface responsive to impact blows that is fixed to the proximate end.

7. The kit of claim 1 further comprising one or more syringes having a Luer lock.

8. The kit of claim 1 wherein said cannula is divided into grades, said grades being markings.

9. The kit of claims 1 wherein said micro-reamer is divided into grades, said grades being markings.

10. The kit of claim 1 wherein the restorative composition comprises a hydrogel.

11. The kit of claim 1 wherein the restorative composition comprises a synthetic bone void filler.

12. The kit of claim 1 wherein the restorative composition comprises polymethylmethacrylate.

13. The kit of claim 1 wherein the restorative composition comprises replicated bone marrow.

14. The kit of claim 1 wherein said catheters are flexible.
