The tissue stimulator includes a plurality of electrodes and a memory for holding a stimulation pulse parameter limit value and a programmed parameter value of a stimulation pulse. A pulse generator applies electrical stimulation pulses to the electrodes in accordance with the programmed parameter value. Programming means is included for receiving remotely generated programming signals and altering the contents of the memory in accordance with the signals. Means is included for comparing the stimulation pulse parameter limit value and the programmed parameter value and for preventing an alteration of the programmed parameter value, unless it is within stimulation pulse parameter limits. The stimulation pulse parameters may include pulse amplitude, pulse width, and pulse rate and the programmed parameter limit values may be upper and lower limits.Field of SearchRemotely changing, (e.g., programming, pacer) parameters or operationElectrical therapeutic systems Electrical treatment of pain Output controlled by sensor responsive to body or interface condition Promoting patient safety or comfort Pulse signal Electrical energy applied through plural paths Spinal cord Control signal storage (e.g., programming) Telemetry or communications circuits | |
