Abstract:
1. A method implemented with a lumen-traveling device, comprising: moving the lumen-traveling device through a body lumen using a propelling mechanism and a steering mechanism on the lumen-traveling device, based at least in part upon a pre-programmed motion pattern; at least intermittently permitting flow of fluid through the body lumen and past a fluid-contacting portion of the lumen-traveling device; detecting a condition of interest with a sensor on the lumen-traveling device; producing a response initiation signal with response initiation circuitry located at least in part on the lumen-traveling device at least partially in response to detection of the condition of interest, wherein the response initiation signal is configured for controlling performance of an action by an active portion of the lumen-traveling device based at least in part on a pre-programmed pattern; and performing the action with the active portion of the lumen-traveling device in response to the response initiation signal.
