Abstract
A medical device includes an end effector configured to apply bipolar energy to target tissue along a working portion thereof and a fluid control system to control the flow of a fluid produced when the end effector applies the bipolar energy to heat the target tissue. The fluid control system includes a fluid path element defining a fluid path, a distal fluid port configured to intake the fluid adjacent to the working portion of an end effector for transport through the fluid path, and a proximal fluid port configured to intake the fluid transported through the fluid path and to exhaust the transported fluid.
