Lumenally-active device
First Claim
1. A lumenally-active system, comprising:
- a structural element configured to fit within at least a portion of a body lumen, the structural element including;
a lumen-wall-engaging portion;
and a fluid-contacting portion configured to contact fluid within the body lumen;
a sensor capable of detecting a condition of interest in the fluid;
response initiation circuitry operatively connected to the sensor and configured to generate a response initiation signal upon detection of the condition of interest in the fluid by the sensor; and
an active portion operatively connected to the response initiation circuitry and capable of producing a response upon receipt of the response initiation signal.

Abstract
Embodiments of a lumenally-active system and method of use and control thereof are disclosed. According to various embodiments, a lumenally-active device is positioned in a body lumen of an organism, where the device may sense a parameter of a fluid in the body lumen and perform an action on the fluid. Control logic and/or circuitry may be located on the device, or the system may include a separate control module. Liquid or gaseous fluids may be treated by embodiments of the device. Actions may include, for example, modification of a body fluid by addition or removal of a material, or by modification of a property of a body fluid or a component thereof.

78. A method of treating a body fluid, comprising:
-
detecting a condition of interest in a fluid within a body lumen with a sensor portion of a lumenally-active system in the body lumen, the lumenally-active system also including a lumen-wall-engaging portion, a fluid-contacting portion configured to contact fluid within the body lumen, and an active portion capable of performing an action within the body lumen;
generating a response initiation signal with response initiation circuitry responsive to detection of the condition of interest in the fluid within the body lumen; and
performing an action within the body lumen with the active portion of the lumenally-active system in response to the response initiation signal. - View Dependent Claims (106, 107, 119, 145, 146, 147, 148)

121. Software for operating a lumenally-active device, comprising:
-
a sensing module capable of receiving and processing a sense signal from a sensor portion of a lumenally-active system in a body lumen, the lumenally-active system also including a lumen-wall-engaging portion, a fluid-contacting portion configured to contact fluid within the body lumen, and an active portion capable of performing an action within the body lumen, and producing as output one or more sense parameters; and
a response initiation module capable of receiving as input the one or more sense parameters and generating as output a response initiation signal to cause the performance of an action within the body lumen with the active portion of the lumenally-active system. - View Dependent Claims (122, 123, 124, 125, 126, 127, 149, 150)
