Abstract: A medical apparatus is provided comprising a delivery device and an algorithm. The delivery device comprises: a plurality of electrodes, a first lead, and a second lead. The plurality of electrodes comprises a first set of electrodes comprising one or more electrodes, and a second set of electrodes comprising one or more electrodes. The first lead comprises the first set of electrodes, and the second lead comprises the second set of electrodes. The delivery device is configured to measure impedance between multiple pairs of electrodes of the plurality of electrodes. The algorithm is configured to determine position information of the first lead and/or the second lead.

Abstract: A system for delivering stimulation energy to a patient is provided. The system comprises a controller, a memory coupled to the controller and storing instructions for the controller to perform an algorithm, and one or more leads for implantation inside a human body. Each lead comprises a plurality of stimulation elements, and each stimulation element can be in one of at least two configuration states. A first configuration state comprises a stimulation element sourcing and/or sinking current, and a second configuration state comprises a stimulation element being in an electrically passive state. The algorithm is configured to determine a stimulation paradigm for stimulating one or more target locations of a patient. The stimulation paradigm defines the configuration state of each of the plurality of the stimulation elements of a first lead. Methods of delivering stimulation energy is also provided.
