Electrode system in iontophoretic treatment devices

摘要

This invention relates to the field of medical devices employing electrophoresis to combat bacterial colonization. More particularly, it relates to an apparatus and method of providing an electrophoresis-type medical device that mitigates the burning of surrounding biological tissue. This invention uses grooves in the contact surface of the medical device for containing the electrodes which cause the electrophoresis to occur. The grooves allow the electrodes to contact biological fluid without contacting and hence burning the surrounding biological tissue. Through the use of this invention it is possible to provide an electrophoresis-type medical device while minimizing the burning of surrounding tissue.
