Patent ID: 8019419

Claim:
A system for stimulating tissue, comprising: at least one leadless, battery-less, implantable subsystem, comprising an energy-storing component a plurality of electrodes coupled to the energy-storing component and configured for generating tissue stimulating pulses, and control means configured for recognizing a first unique identification code transmitted by a matching external controller and for controlling generation of the tissue stimulation pulses; and an external controller, comprising a 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.
