Patent ID: 8419722

Claim:
A method of percutaneously treating a disc that is leaking nucleus pulposus into or through at least one defect in the annulus fibrosus, comprising: advancing a hypodermic needle through skin percutaneously, through the annulus fibrosus and into the nucleus pulposus by piercing the skin, the annulus fibrosus and the nucleus pulposus with the hypodermic needle, wherein the hypodermic needle can be attached to a connector and the hypodermic needle has a distal tip; inserting a fluid delivery tube into the hypodermic needle up to but not beyond the distal tip of the hypodermic needle; wherein the fluid delivery tube has a distal tip and is configured so that the distal tip of the fluid delivery tube does not extend past the distal tip of the hypodermic needle; injecting components of a biologic sealant that begin mixing after the connector and within the space between the distal tip of the hypodermic needle and the distal tip of the fluid delivery tube.
