Abstract
An energy delivery device includes a handle member having a connector on its distal end, the connector including an electrically conductive region. An electrically insulated elongate element extends from the distal that terminates in an uninsulated distal tip. During use, a needle connected to a syringe is inserted through tissue, e.g., into the interior of a spinal disc. A therapeutic agent is delivered through the needle, and then the syringe is disconnected from the needle. The elongate element is inserted into the needle until the distal tip extends beyond the distal end of the needle, and the connector connects the needle to the conductive region. Electrical energy is delivered from a source of electrical energy via the distal tip and the needle to tissue surrounding the passage to close the passage as the needle is withdrawn.
