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.

Claims

1. A composite tool for accessing bone, comprising:

an elongate body, having;

a head having a distal tip configured to penetrate bone, the head being disposed on a distal end of the elongate body;

at least one aperture formed in a sidewall of the elongate body proximal to the distal end and being configured to extrude material radially therethrough and into bone;

a lumen adapted to deliver material to the aperture; and

a guidewire channel formed within at least a portion of the elongate body;

wherein the guidewire channel is collapsible in response to pressurizing material to be delivered through the lumen.

2. The tool according to claim 1, further comprising a source of material under pressure coupled to a proximal portion of the elongate body for delivering the material into the lumen.

3. The tool according to claim 2, wherein the source of material is a hydraulic source.

4. The tool according to claim 2, wherein the material comprises at least one material adapted to function in a capacity other than as a structural support.

5. The tool according to claim 1, wherein the elongate body and the head are integrally formed.

6. The tool according to claim 2, wherein the pressure is at least 40 atmospheres.

7. The tool according to claim 2, wherein the pressure is at least 100 atmospheres.

8. The tool according to claim 1, wherein the elongate body comprises a plurality of extrusion apertures formed in a sidewall thereof adapted to extrude material into bone.

9. The tool according to claim 2, wherein the material comprises PMMA bone cement.

10. The tool according to claim 9, wherein when the material is delivered into the lumen of the elongate body, the material has a viscosity between 600 and 1800 Pascal-seconds for at least 5 minutes.

11. The tool according to claim 1, further comprising a source of material under pressure coupled to a proximal portion of the elongate body, the material comprising PMMA bone cement.

12. The tool according to claim 11, wherein when the material is delivered into the lumen of the elongate body, the material has a viscosity between 600 and 1800 Pascal-seconds for at least 5 minutes.
