1. A lumen-traveling delivery device comprising:
- a propelling mechanism;
a material release portion; and
control circuitry located at least in part on the delivery device, the control circuitry capable of controlling the operation of the propelling mechanism to move the delivery device through the body lumen to a treatment target and controlling the material release portion to release a deliverable material.

Abstract
Lumen-traveling devices capable of controlled material release 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, a material release portion, and/or control circuitry. In some embodiments, a sensor may be used to detect a local condition, and a material may be released from the device in response.

38. A lumen-traveling delivery device comprising:
-
a structural element sized to fit within a body lumen in the vicinity of a treatment target;
at least two wall-engaging structures operable to alternately engage and disengage a wall of the body lumen;
a propelling mechanism capable of producing relative extension and retraction of the at least two wall-engaging structures with respect to each other in combination with alternate engagement and disengagement of the body lumen wall to produce movement of the lumen-traveling delivery device with respect to the body lumen wall; and
a material release portion configured to release a deliverable material. - View Dependent Claims (39, 89, 90)
