Abstract
Medical devices and methods for making and using the same are disclosed. An example medical device may include a control unit for determining an electrical leakage between a first electrode pad and a second electrode pad of an in vivo medical device. The first electrode pad may be spaced from the second electrode pad. The first electrode pad may have an active electrode and a spaced ground electrode. The second electrode pad may have an active electrode and a ground electrode. The ground electrode of the first electrode pad may be electrically connected to the ground electrode of the second electrode pad.
