Device for treating endometriosis

An electrotherapeutic device for at least partial insertion into a patient, the device comprising:

• a shaft including a proximal end portion and a distal end portion, the shaft defining a fluid-impervious gas-delivery lumen extending between the proximal end portion of the shaft, located at a handle connection, and the distal end portion of the shaft;
• one or more plasma activation electrodes located near the distal end portion of the shaft, the one or more plasma activation electrodes configured to be actuatable for establishing a plasma from gas delivered to the distal end portion of the shaft via the fluid-impervious gas-delivery lumen
• an electromagnetic ablation electrode configured to be actuatable for generating electromagnetic ablation energy, the electromagnetic ablation electrode mounted in a fixed location on an external surface of the distal end portion of the shaft and offset from the plasma activation electrode;
• a shield, both lateral to and outside of both of the shaft and the fluid-impervious gas-delivery lumen, the shield configured to be translated longitudinally and independently from the electromagnetic ablation electrode to selectively physically shield a distal tip of the electromagenetic ablation electrode from plasma generated by the plasma activation electrode when the plasma generation electrode is extended distally outward from the shaft;
• and
• a handle connected to the proximal end portion of the shaft, the handle comprising a first trigger for actuating the one or more plasma activation electrodes and a second trigger for actuating the one or more electromagnetic ablation electrodes.
