Abstract:
1. A catheter delivery device to transmit radiofrequency energy to a spinal canal, comprising: a needle having an open proximal end and an open distal end, and a lumen that extends from the open proximal end to the open distal end; a catheter having a blunt, metallic tip on a distal end of the catheter that transmits a radio frequency energy to the treatment site, wherein the catheter is telescopically disposed within the needle lumen to allow the tip to be maneuverably positioned within the spinal canal; a catheter hub coupled to a proximal end of the catheter a metallic wire element telescopically disposed within a lumen of the catheter; and an adapter hub coupled to a proximal end of the wire element, wherein the adapter hub is cooperatively engageable to the catheter hub to form a single shaft, wherein a proximal end of the adapter hub is configured couple to a radio frequency generating device, and wherein the adapter hub and the catheter hub are sized and dimensioned relative to one another such that engagement of the adapter hub to the catheter hub allows a distal end of the wire element to touch a seating surface of the tip such that the wire element delivers a radio frequency energy from the radio frequency generating device to the tip.
