Electrosurgical Device with Offset Conductive Element

A device for forming a lesion insertable into a hub defining a passageway therethrough and having a mounting structure at one end of the passageway, a shaft attached to the hub and defining a lumen therethrough having a longitudinal axis and having a proximal end being attached to the hub in communication with the passageway, the shaft having a distal end extending away from the hub, the shaft including an electrically conductive material on at least a portion of an inner surface and an electrically conductive material on at least a portion on an outer surface, the device comprising:

• a conductive member having a longitudinal axis, the conductive member being attached to a mounting structure mateable with the mounting structure of the hub so that the conductive member extends through the passageway into the lumen so that at least near the hub the conductive member longitudinal axis is spaced from the lumen longitudinal axis, thereby assisting in creating electrical contact between the conductive member outer surface and the shaft inner surface.
