Bipolar tonsillar probe
First Claim
1. A bipolar electrosurgical probe for volumetric shrinkage of tonsil tissue comprising:
- a) an elongated insulated handle having a straight axis and having at a first end means for connecting to a bipolar outlet of electrosurgical apparatus and having at a second end two laterally-spaced needles that have straight bare ends with sharpened points for submucosal penetration of tonsil tissue, b) the bare ends having a length of 1.3-1.7 cm, c) the bare ends extending at an angle to the handle axis of 60-90°
such as to allow the two bare ends to enter submucosally penetrated tissue so that bipolar electrosurgical currents from the two needles when the electrosurgical apparatus is activated cause volumetric shrinkage of tonsil tissue.

Abstract
An RF tonsillar probe comprises a generally elongated insulated structure having means for coupling to the bipolar outlet of electrosurgical apparatus, and two internal insulated wires leading to a distal end that is angled downwardly and that terminates in two laterally-spaced needle electrodes whose tips are exposed. The probe works best with relatively high-frequency RF electrosurgical currents in excess of 1.5 MHz. The combination of the bipolar mode with electrosurgical currents in the MHz range causes relatively low tissue temperatures avoiding the need for the addition of a complicated temperature-controller structure and suitable circuitry, and the bipolar action confines the RFTA effect to the tissue region between the two active needle electrodes.

9. A procedure for volumetric shrinkage of tonsil tissue, comprising the steps:
-
i) providing electrosurgical apparatus capable of supplying electrosurgical currents in the MHz range and having a bipolar outlet for receiving a bipolar connector;
ii) connecting to the bipolar outlet a bipolar electrosurgical probe for radiofrequency thermal ablation, said electrosurgical probe comprising;

such as to allow the two bare ends to enter submucosally penetrated tissue so that bipolar electrosurgical currents from the two needles when the electrosurgical apparatus is activated cause volumetric shrinkage of tonsil tissue;
iii) penetrating submucosally the tonsil tissue to be shrunk with the sharpened points;
iv) activating the electrosurgical apparatus until the penetrated tissue between the needles is damaged causing volumetric shrinkage of the penetrated tissue. - View Dependent Claims (10, 11, 12)
