A medical apparatus for a patient comprises an external system and an implantable system. The external system is configured to transmit one or more transmission signals, each transmission signal comprising at least power or data. The implantable system is configured to receive the one or more transmission signals from the external system, and to deliver stimulation energy to the patient. Methods of delivering stimulation energy are also provided. 147.-. (canceled)48. A medical apparatus for a patient , comprising:an implantable system including a first implantable device comprising:a first lead comprising a first set of multiple stimulation elements comprising at least a first stimulation element and a second stimulation element, wherein the first set of multiple stimulation elements are configured to deliver stimulation energy to the patient; andan implantable controller comprising a current source,wherein the controller is configured to:configure the first stimulation element elements as a cathode, and configure the second stimulation element and each of any additional stimulation elements as an anode;wherein the current source is configured to deliver a first current pulse to the first stimulation element, wherein the first current pulse passes through tissue and is received by the second stimulation element and each of the any additional stimulation elements;wherein the controller is further configured to measure a first voltage pulse that results at the first stimulation element due to the delivery of the first current pulse; andwherein the controller is further configured to determine the approximate impedance of the first stimulation element based on the resulting first voltage pulse.49. The apparatus according to claim 48 , wherein the approximate impedance of the first stimulation element is an upper bound of the actual impedance of the first stimulation element.50. The apparatus according to claim 48 , wherein the controller is further configured to: ...
