EXPANDABLE ENERGY DELIVERY DEVICES HAVING FLEXIBLE CONDUCTIVE ELEMENTS AND ASSOCIATED SYSTEMS AND METHODS
First Claim
1. An energy delivery device for treating an airway in a patient, the energy delivery device comprising:
- an elongated support configured to be passed through a lumen of a scope;
a compliant inflatable member attached to the elongated support, the inflatable member being configured to move between a collapsed configuration and an expanded configuration; and
a flexible conductive element carried by the inflatable member, wherein the flexible conductive element extends along a path and is configured to expand and contract longitudinally relative to the path as the inflatable member moves between the expanded and collapsed configurations.

Abstract
Devices, systems, and methods are disclosed for providing energy to tissue in an internal passageway. An energy delivery device for treating an airway in a patient in accordance with one embodiment of the disclosure can include an elongated support configured to be passed through a lumen of a scope and a compliant inflatable member attached to the elongated support. The inflatable member is configured to move between a collapsed configuration and an expanded configuration. The energy delivery device can also include a flexible conductive element carried by the inflatable member. The flexible conductive element extends along a path and is configured to expand and contract longitudinally relative to the path as the inflatable member moves between the expanded and collapsed configurations.
