Abstract
An electrosurgical device includes a tubular shaft defining a shaft lumen, and a tubular electrode defining an electrode lumen, the electrode being coupled to the shaft. In a straight configuration, the electrode is configured to retain fluid within the electrode lumen, and, in a bent configuration, the electrode is configured to release fluid from within the electrode lumen to an exterior of the electrode.
Claims25
An electrosurgical device, comprising:
- a tubular shaft defining a shaft lumen;
- and
- a tubular electrode defining an electrode lumen, the electrode being coupled to the shaft,
- wherein, in a straight configuration, the electrode is configured to retain fluid within the electrode lumen, and
- wherein, in a bent configuration, the electrode is configured to release fluid from within the electrode lumen to an exterior of the electrode.
An electrode for an electrosurgical device, the electrode comprising:
- an elongated tubular wall defining a central axial lumen,
- wherein, in a straight configuration of the electrode, the wall is configured to retain fluid within the lumen, and
- wherein, in a bent configuration, the wall is configured to release fluid therethrough from within the lumen to an exterior of the electrode.
A method for treating tissue using electrical energy, the method comprising:
- discharging fluid retained within an electrode by causing the electrode to bend to release the fluid to an exterior of the electrode;
- providing, radio-frequency energy to the electrode to energize the electrode;
- contacting tissue with the energized electrode and the released fluid.
An electrosurgical device, comprising:
- a tubular shaft defining a shaft lumen;
- and
- a plurality of electrodes coupled to the shaft,
- wherein the plurality of electrodes are independently electrically connectable to a power source, and
- wherein each of the electrodes is configured to be energized by the power source independently of the other of the electrodes.
