0008. The coblation systems and methods described herein provide for a flow of fluid to the ablation site such that gas bubbles formed during the ablation procedure are removed at a rate that allows for optimal visualization through ultrasonic guidance of the procedure, hithe systems and methods, fluid is delivered through one or more delivery channels and removed through one or more aspiration channels at the same time. As a result, the fluid preferably moves into and out of the ablation site, with gas bubbles formed as a part of the ablation process being removed with the fluid passing into the one or more aspiration channels. The fluids used may include, eg, Ringer's lactate solution, and other solutions suitable for use in coblation procedures.
