Medical device for treating airways and related methods of use
First Claim
1. A medical device, comprising:
- an expandable member movable between a collapsed configuration and one or more expanded configurations, the expandable member including a plurality of energy delivery elements, wherein at least some of the energy delivery elements are configured to be activated separately from a remainder of the energy delivery elements; and
a control unit configured to;
receive a measurement from a sensor unit or from at least one of the plurality of energy delivery elements, wherein the measurement is indicative of a size of a body lumen in which the expandable member is disposed;
activate a first number of the plurality of energy delivery elements when the control unit determines, based on the measurement, that the expandable member is at a first expanded configuration, the first number being at least one; and
activate a second number of the plurality of energy delivery elements when the control unit determines, based on the measurement, that the expandable member is at a second expanded configuration, the second number being greater than the first number.

Abstract
A medical device for treating an airway of a patient. The medical device may include an elongate tubular member having a proximal end, a distal end, and a lumen extending therebetween. The medical device may also include a plurality of conductive elements disposed on a surface of the elongate tubular member. In some embodiments, at least one of the plurality of conductive elements may be disposed distally of another of the plurality of conductive elements. In addition, each of the plurality of conductive elements may be electrically coupled to a surface of the lumen. The medical device may also include a piston movably disposed within the lumen. The piston may include a distal portion configured to make electrical contact with one or more of the plurality of conductive elements.

11. A medical device, comprising:
-
an expandable member movable between a collapsed configuration and one or more expanded configurations, the expandable member including a plurality of energy delivery elements; and a control unit configured to receive a measurement from a sensor unit or from at least one of the plurality of energy delivery elements, and wherein the control unit is configured to activate only some of the plurality of energy delivery elements when the control unit determines, based on the measurement, that the expandable member is expanded to a first diameter, and wherein the control unit is configured to activate all of the plurality of energy delivery elements when the control unit determines, based on the measurement, that the expandable member is expanded to a second diameter, wherein the second diameter is greater than the first diameter. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of delivering energy to a body, the method comprising:
-
determining a size of a first body lumen with a sensor unit or a medical device, wherein the medical device includes an expandable member movable between a collapsed configuration and one or more expanded configurations, the expandable member including a plurality of energy delivery elements; activating at least one of the plurality of energy delivery elements when the medical device is positioned within the first body lumen and based on the determined size of the first body lumen; determining a size of a second body lumen with the sensor unit or the medical device, wherein the size of the second body lumen is larger than the size of the first body lumen; and activating more of the plurality of energy delivery elements than were activated in the first body lumen when the medical device is positioned within the second body lumen and based on the determined size of the second body lumen. - View Dependent Claims (18, 19, 20)
