Abstract
The present disclosure includes an electrosurgical apparatus for treating tissue at a target site. The apparatus has a shaft with a proximal end and a distal portion, the distal portion comprising a return electrode and electrode support. There is also at least one active electrode on the shaft distal portion, which has a proximal portion and a distal portion and a plurality of aspiration apertures disposed therebetween. These apertures are fluidly connected to a fluid aspiration cavity that is located within the electrode support, and the cavity is connected with a fluid aspiration element that is located along the shaft. The plurality of apertures vary in size and are generally arranged so that the larger sized apertures are disposed towards the electrode proximal portion and the smaller sized apertures are generally located towards the electrode distal portion.
