Abstract
An implantable medical device, having a neural stimulator adapted to generate neural stimulation signals, an electrode configuration tester for testing a first electrode configuration for stimulating a desired neural target, and a controller. The controller is configured to control the neural stimulator to selectively provide a first neural stimulation signal with appropriate signal characteristics to stimulate the desired neural target using the first electrical configuration and a second neural stimulation signal with appropriate signal characteristics to stimulate the desired neural target using a second electrode configuration, and adapted to communicate with the electrode configuration tester and to respond to an indication that an efficacy of the first electrode configuration is lower than a threshold by providing the neural stimulation using the second neural stimulation signal.
