Abstract

Gastrointestinal (GI) dysmotility and associated conditions affect over 20% of population, yet pharmacological, behavioural, and surgical interventions offer limited therapeutic efficacy. Targeted electrical stimulation addressing underlying neuromuscular pathology stands to transform our ability to treat dysmotility. Here, we developed a closed-loop GI neuroprosthesis which activates or relaxes GI tract musculature through electrochemical stimulation in response to sensed food stimuli. We additionally describe a tool supporting minimally invasive endoscopically guided implantation that can penetrate the mucosa, accurately localize the submucosa, and safely deploy this device to directly interface with the enteric nervous system. The neuroprosthesis enables generation of coordinated peristaltic waves, significantly increasing the motility rate in a swine model of oesophageal and stomach dysmotility (p
