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.

Abstract
Lumen-traveling devices and associated methods and systems are described. Lumen-traveling devices capable of traveling within a body lumen may include a propelling mechanism to produce movement of the lumen-traveling device within the lumen, as well as additional components such as a sensor, an active portion, and/or control circuitry. In some embodiments, a sensor may be used to detect a local condition, and an action may be performed within the body lumen. Actions that may be performed include, but are not limited to, transmitting information, releasing a material within the lumen, performing a surgical step, or collecting a sample, among others.

12. Logic for controlling a lumen-traveling device, comprising:
-
a sensing module configured to process an input from a sensor on the lumen-traveling device to generate a sense signal indicating detection of a condition of interest in a body lumen of an organism; a response initiation module configured to receive the sense signal from the sensing module and based at least in part upon the sense signal to generate a response initiation signal configured for causing an action to be performed in the body lumen by an active portion of the lumen-traveling device based at least in part upon a pre-programmed pattern; and a motion control module configured to control a propelling mechanism and a steering mechanism on the lumen-traveling device based at least in part upon a pre-programmed motion pattern to control direction or rate of movement of the lumen-traveling device through the body lumen. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method of using a lumen-traveling device, comprising:
-
moving a self-propelling lumen-traveling device through a body lumen with 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 treatment target based at least in part upon detection of a condition of interest in the body lumen with a sensor on the lumen-traveling device; producing a response initiation signal at least in part in response to detection of the condition of interest with response initiation circuitry located at least in part on the lumen-traveling device; and delivering a treatment determined at least in part by a treatment pattern stored in the lumen-traveling device to the treatment target with an active portion of the lumen-traveling device in response to the response initiation signal. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
