An electrosurgical system is disclosed comprising a generator configured to electrosurgical coagulation waveforms. A dip coating process is utilized to minimize waste and to customize coating thickness and drug loading directly at the clinical site just prior to therapeutic use on a patient. A counterweight is mounted in the handle assembly which, during relative motions of parts induced by acceleration from a side impact, resists unlatching the handle. In addition, it has a high solvency and a very low ozone depletion potential.
