Neurostimulation programmer and method for directly assigning parameter values to electrodes
First Claim
1. An external control device for use with a neurostimulator coupled to a plurality of electrodes capable of conveying electrical stimulation energy into tissue in which the electrodes are implanted, comprising:
- a user interface configured for receiving direct input from a user specifying a target value for a target electrode, the user interface including a display screen configured for displaying graphical representations of the electrodes;
a controller/processor configured for, in response to the direct user input, assigning a new stimulation amplitude value to the target electrode; and
output circuitry configured for transmitting the new stimulation amplitude value to the neurostimulator,wherein the controller/processor is configured for, in response to the direct user input, assigning new stimulation amplitude values to an adjusted set of electrodes having a same polarity as the target electrode in accordance with a predetermined rule, the new stimulation amplitude values are fractionalized electrical current values and the predetermined rule is a Ratio Maintenance Rule (RMR) configured to maintain a total of the fractionalized electrical current values to be one hundred percent and compute a new fractionalized electrical current value assigned to each electrode of the adjusted electrode set in accordance with a ratio equal to a fractionalized electrical current value presently assigned to each respective electrode of the adjusted electrode set multiplied by a fractionalized current available to be assigned to the adjusted electrode set divided by a total of fractionalized electrical current values presently assigned to the adjusted electrode set.
