Electrosurgical probe apparatus
First Claim
1. An electrosurgical probe for use in the treatment of tissue comprising:
- an elongated substrate member having a peripheral surface of dielectric material and a longitudinal axis extending between a working end and an attachment end;
at least a pair of electrically isolated electrodes only on said peripheral surface of said substrate member and extending continuously between an active region at said working end and an electrical terminal region at said attachment end for selective connection/disconnection, respectively, to opposite poles of a source of electrical energy; and
an outermost dielectric covering on said substrate member at a region extending intermediate said attachment end and said working end and overlying said electrodes as a continuous peripheral band between said active region and said electrical terminal region to electrically isolate said intermediate region.

Abstract
A disposable bipolar electrosurgical probe which can be readily applied to the tissue to be treated, then discarded. The probe comprises an elongated substrate member having a peripheral surface of dielectric material and a longitudinal axis extending between a working end and an attachment end. At least a pair of electrically isolated electrodes extend continuously on the peripheral surface of the substrate member between an active region at the working end and an electrical terminal region at the attachment end for quick connection and/or disconnection, respectively, to opposite poles of an RF generator. A handle with a quick disconnect mechanism is provided to physically support the probe and enable it to be selectively energized. The probes can be of a fail safe construction so as to assure that only a proper probe can be used for a desired treatment.
