Shifting between electrode combinations in electrical stimulation device
First Claim
1. A method comprising:
- delivering electrical stimulation to a patient via a first subset of a plurality of electrodes;
delivering electrical stimulation to the patient via a second subset of the electrodes; and
receiving a signal representative of a time-domain user input that specifies incrementally adjusting a level of at least one of the electrical stimulation delivered to the patient via the first subset of the electrodes and the electrical stimulation delivered to the patient via the second subset of the electrodes.

Abstract
The disclosure is directed to techniques for shifting between two electrode combinations. An amplitude of a first electrode combination is incrementally decreased while an amplitude of a second, or subsequent, electrode combination is concurrently incrementally increased. Alternatively, an amplitude of the first electrode combination is maintained at a target amplitude level while the amplitude of the second electrode combination is incrementally increased. The stimulation pulses of the electrode combinations are delivered to the patient interleaved in time. In this manner, the invention provides for a smooth, gradual shift from a first electrode combination to a second electrode combination, allowing the patient to maintain a continual perception of stimulation. The shifting techniques described herein may be used during programming to shift between different electrode combinations to find an efficacious electrode combination. Additionally, the techniques may be used for shifting between different electrode combinations associated with different stimulation programs or program sets.
