RADIO FREQUENCEY CATHETER TO TARGET LIGAMENTUM FLAVUM
First Claim
1. A device for performing a surgical procedure comprising:
- an elongated shaft extending between a proximal end and a distal end and includes an outer surface and an inner surface, the inner surface defining a passageway;
a stylet configured for moveable disposal within the passageway of the elongated shaft and the stylet includes a blunt distal tip configured for disposal outside the distal end of the elongated shaft and to prevent damage to adjacent tissue;
an expandable member including a proximal end and a distal end, wherein the proximal end of the expandable member is disposed with the distal end of the elongated shaft and the distal end of the expandable member is connected to the distal end of the stylet; and
at least one electrode disposed with the expandable member.
