Abstract:
An implantable cardiac stimulation lead system for use with a stimulation device including an implantable housing containing a pulse generator which emits stimulation pulses, the lead system comprising:a plurality of electrodes that return to the stimulation device stimulation pulse current after traversing heart tissue; and a matrix switching system comprising: X electrical conductors extending between a proximal connector releasably coupled to the stimulation device and extending to the matrix switching system and connected thereto; Y electrical conductors extending between the proximal connector releasably coupled to the stimulation device and extending to the matrix switching system and connected thereto; and wherein the matrix switching system comprises a switching array comprising plural switching devices to connect within the switching array each of the Y electrical conductors to each single X electrical conductor and also to each of the electrodes; wherein one of the switching devices is actuated by a corresponding pulse from the pulse generator applied to corresponding X and Y conductors connected to the switching device.
