Abstract

A method of treating a disc that is leaking nucleus pulposus through at least one defect in the annulus fibrosus. The method includes injecting a fibrin sealant into the disc to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises an anesthetic, fibrinogen and an activating compound, wherein at least a portion of the fibrin forms after injection, with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc.

Claims (21)

1. A method of treating a disc that is leaking nucleus pulposus through at least one defect in the annulus fibrosus, comprising: injecting a fibrin sealant into the disc to reduce at least a portion of the at least one defect, wherein the fibrin sealant injected into the disc comprises an anesthetic, fibrinogen and an activating compound, wherein at least a portion of the fibrin forms after injection, with the proviso that a corticosteroid is absent from the fibrin sealant injected into the disc, wherein the injecting occurs by inserting an introducer needle having a tip through skin and into the intra-discal space to a position adjacent to the at least one defect, inserting a second needle through the introducer needle up to but not beyond the tip of the introducer needle, and injecting at least one component of the fibrin sealant through the introducer needle, and injecting the other components of the fibrin sealant through the second needle such that the initial contact of the fibrin sealant components occurs at the tip of the second needle, and with the proviso that neither the nucleus pulposus nor the annulus fibrosus has been heated.

2. The method of claim 1 , wherein the fibrin sealant consists essentially of fibrinogen, the activating compound and the anesthetic, optionally at least one additive, and optionally calcium chloride.

3. The method of claim 2 , wherein the fibrin sealant consists of fibrinogen, an activating compound and the anesthetic, optionally the at least one additive, and optionally containing calcium chloride.

4. The method of claim 1 , wherein calcium chloride is injected with the fibrinogen and the activating compound.

5. The method of claim 1 , wherein the activating compound is thrombin.

6. The method of claim 1 , wherein the anesthetic is lidocaine, sarapin or bupivicaine.

7. The method of claim 1 , wherein at least one additive is also injected.

8. The method of claim 1 , wherein no portion of the nucleus pulposus has been removed by surgery.

9. The method of claim 1 , wherein the at least one defect is a tear or fissure in the annulus fibrosus.

10. The method of claim 1 , wherein normal hydrostatic pressure in the disc is restored.

11. The method of claim 1 , wherein normal disc height is restored.

12. The method of claim 1 , wherein the fibrinogen is autologous.

13. The method of claim 1 , wherein the injection is performed using a dual barrel syringe.

14. The method of claim 1 , wherein the activating compound is thrombin, and wherein a mixture of anesthetic, fibrinogen and thrombin is injected.

15. The method of claim 1 , wherein the activating compound is thrombin, and wherein the fibrinogen and thrombin are injected sequentially and at least partially mix in the disc.

16. The method of claim 1 , wherein the anesthetic is injected sequentially either before, with or after the fibrinogen and thrombin and at least partially mix in the disc.

17. The method of claim 1 , wherein the disc is injected with the fibrin sealant at multiple points.

18. The method of claim 1 , wherein the disc is a lumbar disc.

19. The method of claim 1 , wherein the disc is a cervical disc.

20. The method of claim 1 , wherein the disc is a thoracic disc.

21. The method of claim 1 , wherein a contrast agent is injected either before the fibrin sealant, with the fibrin sealant, or after the fibrin sealant has been injected.
