Electrosurgical device with offset conductive element
First Claim
1. A device for forming a lesion comprising:
- 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 lumen therethrough having a longitudinal axis, the shaft having a proximal end attached to the hub in communication with the passageway and 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 of an outer surface; and
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, wherein the conductive member longitudinal axis is spaced apart from the lumen longitudinal axis by an offset, thereby assisting in creating electrical contact between the conductive member outer surface and the shaft inner surface.

Abstract
A device for forming a lesion includes a hub defining a passageway and a shaft attached to the hub and defining a lumen. The shaft has a proximal end and a distal end extending away from the hub. The shaft includes an electrically conductive material on at least a portion of an inner surface and on at least a portion on an outer surface. A conductive member has a longitudinal axis and is attached to a mounting structure mateable with 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 to create electrical contact between the conductive member outer surface and the shaft inner surface.
