Visualization of the Colon Through Use of the Magnetic Flexible Endoscope (MFE) in Participants With Inflammatory Bowel Disease (IBD)

Colonoscopy is the gold standard for making the diagnosis, following clinical response, establishing prognosis, and creation of management plans for patients with Inflammatory Bowel Disease (IBD). While colonoscopy is a relatively safe procedure, there are several limitations due to the unintuitive drive mechanism and mechanical design of current conventional colonoscopes. Additionally, for patients with IBD, the procedure is associated with a higher lifetime risk of adverse event due to increased frequency of examination-more than a 6-fold increased risk when compared to their non-IBD counterparts. For these reasons, our team has developed a novel, highly compliant, Magnetic Flexible Endoscope (MFE) with the functionality of a conventional colonoscope (i.e. camera, therapeutic channel, irrigation, insufflation, illumination, lens cleaning). The MFE is driven by magnetic coupling of the endoscope head that contains an internal permanent magnet and a robotic arm that holds an external permanent magnet. This enables a "front-pull" actuation mechanism to eliminate the need for pushing a semi-rigid insertion tube for advancement. The forward drive mechanism thus prevents buckling of the insertion tube and avoids looping/colon wall stress. This reduces the risk of perforation and pain during the procedure to allow for less (if any) procedural sedation. The Magnetic Flexible Endoscope (MFE) is a single-use endoscope intended to integrate with other commercially available devices for the visualization of a human colon in order to eliminate the need for passage of the much stiffer, non-intuitive, risk prone standard colonoscope. This study builds on the successful completion of the first-in-human feasibility study that demonstrated safety and tolerability in healthy patients who were already scheduled for their routine standard-of-care screening colonoscopy. In this secondary study, the MFE device will be inserted into the rectum via the anus and navigated through the colon to the cecum, using magnetic manipulation, in patients with stable, non-active, Inflammatory Bowel Disease (IBD) who are due for their IBD/colorectal cancer surveillance/screening colonoscopy exams. The investigators plan to assess safety and tolerability of MFE navigation in the colon from the rectum to the cecum in patients with stable non-active IBD who are due for their IBD/Colorectal Cancer surveillance/screening colonoscopy exams. This will be a parallel study design in which three of six patients will have standard of care colonoscopy completed with monitored anesthesia care (MAC) first followed by MFE and three of six patients will undergo unsedated MFE first followed by standard of care colonoscopy completed with MAC.
