Waveforms for electrical stimulation therapy
First Claim
1. A method comprising controlling, via at least one processor, delivery from a medical device to a target location of a gastrointestinal (GI) tract of a patient of a sequence of pulses at a specified frequency, with each pulse having a single polarity, with all even numbered pulses in the sequence having one polarity and all odd numbered pulses in the sequence having an opposite polarity, in a fashion such that respective intervals between consecutive pulses in the sequence increases with decreases in the specified frequency of delivery, and decreases with increases in the specified frequency of delivery.

Abstract
In some examples, the disclosure relates to a systems, devices, and techniques for delivering electrical stimulation therapy to a patient. In one example, the disclosure relates to a method including delivering a series of pulses with alternating pulse polarities to a gastrointestinal tract of a patient. The series of pulses includes at least a first pulse of a first polarity, a second pulse of a second polarity, and a third pulse of the first polarity, where the first, second and third pulses are delivered in direct succession and in that order. The first and second pulses are separated by a first time delay and the second and third pulses are separated by a second time delay. In some examples, each of the first and second time delays depend on the frequency that the series of pulses are delivered.

2. A medical device system comprising:
-
a stimulation generator configured to generate and deliver a series of pulses having alternating pulse polarities to a patient; and a processor configured to control the series of pulses generated and delivered by the stimulation generator, wherein the device is configured to deliver the series of pulses to a target location of a gastrointestinal (GI) tract of a patient, wherein each pulse having a single polarity, with all even numbered pulses in the sequence having one polarity and all odd numbered pulses in the sequence having an opposite polarity, in a fashion such that respective intervals between consecutive pulses in the sequence increases with decreases in the specified frequency of delivery, and decreases with increases in the specified frequency of delivery.

3. A non-transitory computer-readable storage medium comprising instructions to cause a programmable processor to control a stimulation generator to deliver a series of pulse pairs with alternating pulse polarities from a medical device to a target location of a gastrointestinal (GI) tract of a patient, wherein each pulse has a single polarity, with all even numbered pulses in the sequence having one polarity and all odd numbered pulses in the sequence having an opposite polarity, in a fashion such that respective intervals between consecutive pulses in the sequence increases with decreases in the specified frequency of delivery, and decreases with increases in the specified frequency of delivery.
- 4. A method comprising controlling, via at least one processor, delivery of a series of pulses with alternating pulse polarities from a medical device to a target location of a gastrointestinal (GI) tract of a patient, wherein the series of pulses includes at least a first pulse of a first polarity, a second pulse of a second polarity, a third pulse of the first polarity, and a fourth pulse of the second polarity, wherein the first, second, third and fourth pulses are delivered to the target location in direct succession, in that order, wherein the first pulse and second pulse are separated by a first time delay, the second pulse and third pulse are separated by a second time delay, the third pulse and the fourth pulse are separated by a third time delay, and wherein an increase in a pulse frequency of the series of pulses causes the first time delay, the second time delay, and third time delay to decrease in duration, and a decrease in the pulse frequency of the series of pulses causes the first time delay, the second time delay, and third time delay to increase.
