Claim 11

An improved electrosurgery electrode for as set forth in claim 1 including tip insulating means for insulating said electrode tip to expose only the distal end of said electrode tip from approximately 0.04 inches to 0.05 inches.

Claim 12

An improved electrosurgery electrode as set forth in claim 1 wherein said electrode tip comprises a hooked blade.

Claim 13

An improved electrosurgery electrode for cooperation with an electrode holder connected to a source of electrical power and with an introducer catheter, comprising in combination: a solid electrode shaft having a first and a second end; a shaft connecting means for electrically connecting said first end of said electrode shaft to the electrode holder; an insulating hub disposed proximate said first end of said electrode shaft for insulating said shaft connecting means and for forming a substantially waterproof seal when said first end of said electrode shaft is connected to the electrode holder; said insulating hub including an aperture defined in said insulating hub with said aperture receiving said first end of said electrode shaft therein; an electrode tip having a proximal and distal end; said distal end of said electrode tip comprising a hook extending generally perpendicular from an axis extending through said electrode shaft; said second end of said electrode shaft including a bore axially extending into said shaft with said proximal end of said electrode tip extending from said bore, electrically connecting said distal end of said electrode tip to said second end of said electrode shaft; said distal end of said electrode tip extending beyond the surface of said electrode shaft a distance generally equal to or less than the radius of said electrode shaft thereby enabling said electrode tip to pass through the introducer catheter; and an insulating shaft tubing means for providing an electrical insulation between an exposed portion of said electrode tip and said insulating hub.

Claim 14

An improved electrosurgery electrode for cooperation with an electrode holder connected to a source of electrical power and with an introducer catheter, comprising in combination: a solid electrode shaft having a first and a second end; a shaft connecting means for electrically connecting said first end of said electrode shaft to the electrode holder; an insulating hub disposed proximate said first end of said electrode shaft for insulating said shaft connecting means and for forming a substantially waterproof seal when said first end of said electrode shaft is connected to the electrode holder; said insulating hub including an aperture defined in said insulating hub with said aperture receiving said first end of said electrode shaft therein; an electrode tip having a proximal and distal end; said distal end of said electrode tip comprising a hook extending generally perpendicular from an axis extending through said electrode shaft; said second end of said electrode shaft including a bore axially extending into said shaft with said proximal end of said electrode tip extending from said bore, electrically connecting said distal end of said electrode tip to said second end of said electrode shaft; said distal end of said electrode tip extending beyond the surface of said electrode shaft a distance generally equal to or less than the radius of said electrode shaft thereby enabling said electrode tip to pass through the introducer catheter; and an insulating shaft tubing means for providing an electrical insulation between an exposed portion of said electrode tip and said insulating hub.
