Abstract
A system and method for preventing the undesirable dissipation of charge throughout a tissue surface while maintaining the charge density at a desired tissue treatment site. The invention embodies a physical perimeter conductor positioned in proximity to a tissue surface and a conductance control circuit working in combination to collect surface charge applied within the confines of the perimeter conductor and to maintain a desired relationship between the contained surface charge density and time.
