Translational development and pre-clinical evaluation of prototype gastrointestinal mock-up devices: only robotic placement of plastic?
2020
Background: The aim of this study was to address the vision of wireless theranostic devices distributed along the gastrointestinal (GI) tract by defining design requirements, developing prototype mock-ups, and establishing a minimally invasive surgical approach for the implantation process. Methods: Questionnaires for contextual analysis and use case scenarios addressing the technical issues of an implantable GI device, a possible scenario for implantation, preparation and calibration of a device, and therapeutic usage by professionals and patients were completed and discussed by an interdisciplinary team of surgeons, engineers, and product designers. Two acute porcine experiments were cond…
Robotic Setup Promises Consistent Effects of Multilocular Gastrointestinal Electrical Stimulation: First Results of a Porcine Study
2020
<b><i>Background:</i></b> Electrical stimulation (ES) of several gastrointestinal (GI) segments is a promising therapeutic option for multilocular GI dysmotility, but conventional surgical access by laparotomy involves a high degree of tissue trauma. We evaluated a minimally invasive surgical approach using a robotic surgical system to perform electromyographic (EMG) recordings and ES of several porcine GI segments, comparing these data to an open surgical approach by laparotomy. <b><i>Materials and Methods:</i></b> In 5 acute porcine experiments, we placed multiple electrodes on the stomach, duodenum, jejunum, ileum, and colon. Three experime…
