Locomotive video capsule endoscope using vibration and direction-adjustable cilia to control its motion inside one’s digestive tract
Video capsule endoscopy (VCE) is a noninvasive technology designed to provide diagnostic imaging of the digestive tract. Largely, it provides difficult-to-access visualization of the small bowel, as well as information regarding the esophagus, stomach, and cecum. VCE is appreciated for its ability to offer high diagnostic yield without need for sedation or invasive measures like its traditional endoscopic cousins. However, VCE cannot be maneuvered and relies entirely on the innate peristalsis and administration of pro-kinetic agents to push the device through the GI tract. For example, this limits diagnostic utility in the stomach in particular, as gravity pulls the device to the antrum for the majority of its transit time of the stomach.
