Abstract
An in-vivo examining device, system and method for identifying the presence of strictures in the small bowel are provided. The in-vivo examining device includes a monitoring mechanism that becomes deactivated when exposed to in-vivo substances native to the small bowel or the colon, and a degradable device body that includes at least a first body portion which degrades at a slow rate when exposed to in-vivo substances native to the small bowel and at a fast rate when exposed to in-vivo substances native to the colon. The degradation of the degradable device body exposes the monitoring mechanism to substances native to the small bowel or the colon and thus indicates whether the examining device has safely passed through the small bowel or whether it is retained in the small bowel due to strictures in the small bowel.
