Curable material delivery device with a rotatable supply section

1. An apparatus for introducing material into an injection site of a patient comprising:

a cannula defining a lumen;

a carrier assembly for delivering material from an injector to an injection site, the carrier assembly defining a carrier lumen and the carrier assembly comprising

an injection connector;

a cannula connector;

a supply section and

an inner section, detachable from the supply section and configured to be proximal to the patient, the inner section having a longitudinal axis,

where the supply section is operable to receive curable material,

wherein a supply section portion distant from the inner section extends non-coaxially from the inner section such that the supply section portion distant from the inner section is revolvable around the longitudinal axis of the inner section, where a supply section near the inner section is rotatable around the longitudinal axis of the inner section, and where at least a portion of the inner section is located within the lumen of the cannula.

2. The apparatus of claim 1 wherein the inner section is rotatable and rotation of the inner section is dependent on rotation of the supply section.

3. The apparatus of claim 1 wherein the inner section is rotatable and rotation of the inner section is independent of rotation of the supply section.

4. The apparatus of claim 1 wherein the carrier further comprises a connector for connecting an end of the supply section with an end of the inner section wherein the connector defines a chamber between the end of the supply section and the end of the inner section.

5. The apparatus of claim 4 wherein the connector further comprises a rotating adapter that connects with the end of the supply section.

6. The apparatus of claim 5 wherein the rotating adapter is operative to rotate the supply section not less than about 90 degrees.

7. The apparatus of claim 6 wherein the supply section, chamber and inner section form a lumen having walls defining a substantially smooth transition from the supply section to the inner section.

8. A method of delivering material to an injection site comprising the steps of:

providing an apparatus according to claim 1 , wherein the supply section is configured as a tubular supply section defining a lumen, and the inner section is configured as a tubular inner section;

inserting the cannula into an injection site;

connecting the tubular supply section with an injector containing a volume of material;

advancing material through the tubular supply section from the injector a sufficient distance to dispel a dry plug of material from the tubular supply section;

connecting the tubular inner section of the carrier with the supply section;

pre-loading the lumen of the carrier with the material so that the material is delivered to a distal end of the tubular inner section from the injector, wherein the carrier is thus pre-loaded with material;

inserting at least a portion of the distal end of the pre-loaded tubular inner section into the elongated lumen of the cannula; and

delivering material to an injection site.

9. The method of claim 8 wherein the injection site and a second injection site are within a vertebra.

10. The method of claim 9 wherein the tubular supply section and the tubular inner section are of different diameters.
