Claim:
1. An electrosurgical cannula for use with an electrosurgical generator to treat tissue, comprising: a cylindrical body portion defining a lumen therethrough, the body portion including a non-coring pointed distal tip that includes a penetration portion configured to penetrate tissue and a transition portion configured to connect the penetration portion to a remainder of the body portion, wherein the distal tip is electrically conductive; and at least one thermocouple having a distal end connected to the distal tip, wherein the penetration portion of the distal tip includes a distal edge and a proximal edge, and wherein the distal end of the thermocouple includes a hook portion fixedly secured to the proximal edge of the penetration portion of the distal tip such that at least a first portion of the distal end of the thermocouple extends distally at least partially along a length of the transition portion and at least a second portion of the distal end of the thermocouple extends proximally along an outer surface of the transition portion, and wherein the second portion abuts the outer surface of the transition portion.
