Abstract

A method of treating a vertebra, comprising:
(a) accessing an interior of a vertebra; and (b) introducing a sufficient amount of artificial biocompatible material which does not set to a hardened condition in storage, into said bone, with sufficient force to move apart fractured portions of said bone.

First claim

The invention claimed is:

1. A method of treating a vertebra, comprising:
(a) inserting a delivery device into an interior of a vertebra, the delivery device having a delivery tip with a closed distal end and an aperture that directs the bone cement out of a first side of the delivery device;
(b) extruding bone cement through the aperture and into the bone, wherein the extruded bone cement has a curved shape and a degree of the curvature is controlled via a difference in friction between a proximal side and a distal side of the aperture.

2. The method of claim 1 , wherein the distal side of the aperture has a guided incline that extrudes the cement in the curved shape.

3. A method of treating a vertebra, comprising:
(a) inserting a delivery device into an interior of a vertebra, the delivery device having a delivery tip with a closed distal end and an aperture that directs the bone cement out of a first side of the delivery device;
(b) extruding bone cement through the aperture and into the bone, further comprising moving the delivery device axially during the extrusion of the cement.

4. The method of claim 3 , wherein advancing a pusher through the delivery device toward the delivery tip extrudes the bone cement through the aperture.

5. The method of claim 4 , wherein the pusher is advanced without twisting.

6. The method of claim 3 , further comprising removing and replacing the delivery tip.

7. The method of claim 6 , wherein the delivery tip is replaced by rotating the delivery tip relative to the delivery device.

8. The method of claim 3 , wherein as a portion of the bone cement moves through the delivery tip, the portion of the bone cement has a curved shape.

9. A method of treating a vertebra, comprising:
(a) inserting a delivery device into an interior of a vertebra, the delivery device having a delivery tip with a closed distal end and an aperture that directs the bone cement out of a first side of the delivery device;
(b) extruding bone cement through the aperture and into the bone, further comprising rotating the delivery device during the extrusion of the cement.

10. The method of claim 9 , wherein the delivery device is manually rotated.

11. The method of claim 9 , wherein advancing a pusher through the delivery device toward the delivery tip extrudes the bone cement through the aperture.

12. The method of claim 11 , wherein the pusher is advanced without twisting.

13. The method of claim 9 , further comprising removing and replacing the delivery tip.

14. The method of claim 13 , wherein the delivery tip is replaced by rotating the delivery tip relative to the delivery device.

15. The method of claim 9 , wherein as a portion of the bone cement moves through the delivery tip, the portion of the bone cement has a curved shape.

16. A method of treating a vertebra, comprising:
(a) inserting a delivery device into an interior of a vertebra, the delivery device having a delivery tip with a closed distal end and an aperture that directs the bone cement out of a first side of the delivery device;
(b) extruding bone cement through the aperture and into the bone, further comprising coupling a vibrator to the delivery device prior to extruding the bone cement.

17. A method of treating a vertebra, comprising:
(a) inserting a delivery device into an interior of a vertebra, the delivery device having a delivery tip with a closed distal end and an aperture that directs the bone cement out of a first side of the delivery device;
(b) extruding bone cement through the aperture and into the bone, wherein the extruded bone cement is plastically deformed into a curved shape.

18. The method of claim 17 , wherein the extruded bone cement maintains the curved shape until it contacts bone.
