System and method for displaying stimulation field generated by electrode array
First Claim
1. A programmer for a tissue stimulator that generates a stimulation field between electrodes, comprising:
- a user-controlled input device configured for generating control signals; and
a processor configured for instructing the tissue stimulator to modify the stimulation field between the electrodes in response to the generated control signals, and for generating display signals that can be used to display a representation of a modified stimulation field relative to, and separate from, the electrodes.

Abstract
An implantable pulse generator includes a current steering capability that allows a clinician or patient to quickly determine a desired electrode stimulation pattern, including which electrodes of a group of electrodes within an electrode array should receive a stimulation current, including the amplitude, width and pulse repetition rate of such current. Movement of the selected group of electrodes is facilitated through the use of remotely generated directional signals, generated by a pointing device, such as a joystick. As movement of the selected group of electrodes occurs, current redistribution amongst the various electrode contacts takes place. The redistribution of stimulus amplitudes utilizes re-normalization of amplitudes so that the perceptual level remains fairly constant. This prevents the resulting paresthesia from falling below the perceptual threshold or above the comfort threshold.

14. A tissue stimulation system, comprising:
-
a plurality of electrodes; a tissue stimulator configured for receiving the programming signals and generating a stimulation field between the electrodes in accordance with the programming signals; and an external programmer configured for instructing the generating programming signals in response to user input to modify the stimulation field generated between the electrodes, the external programmer further configured for prompting a monitor to display a representation of the modified stimulation field relative to, and separate from, the electrodes. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
