GASTRIC ELECTRICAL STIMULATION WITH MULTI-SITE STIMULATION ANTI-DESENSITIZATION FEATURE

The disclosure is directed to gastric stimulation programmers, stimulators and methods for controlling delivery of gastric stimulation therapy to maintain the efficacy of the therapy over time. Maintaining the efficacy of gastric stimulation therapy may be possible by implementing one or more anti-desensitization features in a gastric stimulation controller or stimulator. As electrical stimulation therapy is continuously delivered to a patient, the stimulated tissue may become desensitized to the electrical stimulation therapy such that the beneficial effect of the electrical stimulation is diminished. Once desensitization occurs, the affected tissue may not respond favorably to electrical stimulation therapy. Application of one or more anti-desensitization features to control gastric stimulation therapy may reduce or prevent desensitization and effectively extend the efficacy of the therapy over time
