Techniques for current steering directional programming in a neurostimulation system
First Claim
1. An external control device for use with a two-dimensional array of electrodes implanted within tissue and a neurostimulator capable of delivering electrical stimulation energy to the electrodes to create a volume of activation, comprising:
- a user interface including a current steering initiation control element and a current steering direction control element capable of being rotated about an axis;
a controller/processor configured for, in response to actuation of the initiation control element, generating a series of different combinations of the electrodes in a manner that the volume of activation gradually translates in a specific direction when the electrical stimulation energy is delivered to the different electrode combinations, the controller/processor further configured for, in response to rotation of the direction control element about the axis, defining the specific direction in which the volume of activation is translated; and
output circuitry configured for transmitting the different electrode combinations to the neurostimulator.

Abstract
A neurostimulation system comprises at least one neurostimulation lead configured for being implanted within tissue. The neurostimulation lead(s) carries a plurality of electrodes capable of being arranged in a two-dimensional pattern. The neurostimulation system further comprises a neurostimulator configured for delivering electrical stimulation energy to the electrodes to create a volume of activation, and an external control device including a current steering direction control element capable of being rotated about an axis. The external control device is configured for prompting the neurostimulator to deliver the electrical stimulation energy to the electrodes in a manner that gradually translates the volume of activation in a specific direction, and for defining the specific direction in which the volume of activation is translated in response to rotation of the direction control element about the axis.
