Abstract
A tissue stimulation device includes an electrode array having at least four independently switchable electrodes. In one embodiment, the electrode array comprises a flexible base to which the electrodes are fixed that flexes to encompass at least a portion of an artery or other elongate biological structure. The electrodes are electrically coupled to and energized by a signal generator coupled to a control system. In one embodiment, the array of electrodes are configured such that a suitable signal pattern for stimulation pulses between or among a set of the switchable electrodes may be determined without having to reposition the electrode assembly by using a series of signal patterns activating different combinations of switchable electrodes in response to sub-stimulation test signals to determine a signal pattern that provides suitable patient response. In another embodiment, the array of electrodes includes an array of selectively activatable multi-polar electrodes.
