A system is disclosed for stimulating body tissue includes one or more leadless, battery-less, implantable electrodes; and an external controller configured to transmit energy to the implantable electrode(s) via an RF signal for generating tissue stimulating pulses emitted by the respective electrode(s). The external controller is preferably further configured to transmit identification information to the implantable electrode(s) for secured information exchange. The one or more implantable electrodes are preferably each configured to transmit sensed tissue information to the external controller via an RF signal. The system may employ fixation technologies such as screw-in mechanisms, stent-like scaffolding, cuff-type or anchoring mechanisms in order to attach the implanted electrode(s) to respective target body tissues, such as (without limitation) cardiac tissue, brain tissue, bladder tissue, diaphragm, nerve tissue, spine, digestive tract tissue, and muscle tissue.

What is claimed is: 1. A system for stimulating tissue, comprising:at least one leadless, battery-less, implantable subsystem, comprisingan energy-storing componenta plurality of electrodes coupled to the energy-storing component and configured for generating tissue stimulating pulses,andcontrol means configured for recognizing a first unique identification code transmitted by a matching external controller and for controlling generation of the tissue stimulation pulses;andan external controller, comprisinga first unique identification code which identifies the external controller;an RF stage configured to provide operating energy to the energy-storing component(s) of the at least one implantable subsystem;a control unit configured to initiate an identity confirmation phase in which the external controller transmits said first unique identification code to the at least one implanted subsystem;wherein, prior to allowing generation of the tissue stimulation pulses, the control means for the at least one implanted subsystem determine that the external controller is the matching external controller based on whether they recognize the transmitted first unique identification code.
