Closed-Loop Intramuscular Motility Prosthesis, Submucosal Neuromodulation Device and Minimally Invasive Endoscopic Implantation Tool

Articles and systems configured for treating GI motility disorders are generally provided. In some embodiments, an article comprising one or more electrodes (with both sensing and stimulating capabilities) may be configured to stimulate one or more tissues in the GI tract, electrically and/or chemically, to modulate peristalsis and/or allow neuromodulation. In some embodiments, a system comprises a controller that allows for close-loop operation of the article, e.g., such that the article may stimulate (e.g., via a feedback loop) the one or more organs in the GI tract upon receiving sensed parameters in the GI tract. In some embodiments, an implantation tool comprising a sensor may allow for submucosal or intramuscular implantation of an article. The implantation tool and the article may be useful for, for example, as a general platform for delivery of treating GI motility disorders and/or neuromodulation of the GI tract.
