Device, system, and method for controllably reducing inflammatory mediators in a subject
First Claim
Patent Images
1. An intracorporeal device comprising:
- a body structure sized for placement in a blood vessel of a subject, said body structure including;
a sensor configured to detect one or more inflammatory mediators in peripheral blood of a subject;
a treatment chamber configured to receive at least a portion of the peripheral blood through a flow route, the treatment chamber including one or more reactive components configured to alter a functional structure of the one or more inflammatory mediators in the peripheral blood; and
a controller in communication with the sensor and the treatment chamber, the controller configured to control flow of peripheral blood through the flow route into the treatment chamber to achieve a target value of the detected one or more inflammatory mediators in the peripheral blood of the subject.

Abstract
Devices, systems, and methods are provided for controlling an inflammatory response in a subject. Devices, systems, and methods are provided that alter the functional structure of one or more inflammatory mediators in the peripheral blood of the subject. The device or system is useful in a method for treating an inflammatory disease or condition in the subject.

43. An intracorporeal device comprising:
a body structure entirely sized for placement in a blood vessel of a subject, said body structure including; at least one peripheral blood flow route through the body structure; at least one inflammatory mediator sensor positioned in the at least one peripheral blood flow route; at least one controllable reservoir including one or more reactive components configured to alter a functional structure of the one or more inflammatory mediators in the peripheral blood; and a controller in communication with the at least one inflammatory mediator sensor and the at least one controllable reservoir, the controller configured to control release of the one or more reactive components from the at least one controllable reservoir into the peripheral blood to achieve a target value of the detected one or more inflammatory mediators in the peripheral blood of the subject. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)

62. An intracorporeal device comprising:
a body structure entirely sized for placement in a blood vessel of a subject, said body structure including; at least one peripheral blood flow route through the body structure; one or more inflammatory mediator sensors positioned in the at least one peripheral blood flow route; at least one treatment chamber including one or more flow-modulating elements, the at least one treatment chamber configured to controllably receive at least a portion of the peripheral blood from the at least one peripheral blood flow route through the one or more flow-modulating elements; one or more reactive components incorporated into the at least one treatment chamber, the one or more reactive components configured to alter a functional structure of the one or more inflammatory mediators; and a controller operationally linked to the one or more inflammatory mediator sensors and the one or more flow-modulating elements, the controller configured to control flow of peripheral blood from the at least one peripheral blood flow route into the treatment chamber to achieve a target value of the one or more inflammatory mediators in the peripheral blood of the subject.

63. An intracorporeal device comprising:
a body structure entirely sized for placement in a blood vessel of a subject, said body structure including; at least one peripheral blood flow route through the body structure; one or more recognition-based substrate sensors positioned in the at least one blood flow route, the one or more recognition-based substrate sensors configured to sense one or more inflammatory mediators in peripheral blood of the subject; at least one treatment chamber including one or more flow-modulating elements, the at least one treatment chamber configured to controllably receive at least a portion of the peripheral blood from the at least one peripheral blood flow route through the one or more flow-modulating elements; one or more binding agents incorporated into the at least one treatment chamber and configured to alter a functional structure of the one or more inflammatory mediators in the peripheral blood; and a controller operationally linked to the one or more recognition-based substrate sensors and the one or more flow-modulating elements, the controller configured to control flow of peripheral blood from the at least one peripheral blood flow route into the treatment chamber to achieve a target value of the one or more inflammatory mediators in the peripheral blood of the subject.

-
a body structure entirely sized for placement in a blood vessel of a subject, said body structure including; at least one peripheral blood flow route through the body structure; at least one recognition-based substrate sensor positioned in the at least one peripheral blood flow route, the at least one recognition-based substrate sensor configured to sense one or more inflammatory mediators in peripheral blood; at least one controllable reservoir including one or more binding agents configured to alter a functional structure of the one or more inflammatory mediators in the peripheral blood; and a controller in communication with the at least one recognition-based substrate sensor and the at least one controllable reservoir, the controller configured to control release of the one or more binding agents from the at least one controllable reservoir and into the peripheral blood to achieve a target value of the detected one or more inflammatory mediators in the peripheral blood of the subject.
