Abstract
Systems, delivery devices, and methods to treat, ablate, damage, or otherwise affect tissue in an airway of a patient. The treatment systems are capable of delivering a coolable ablation assembly that ablates targeted tissue while cooling non-targeted tissue to protect the non-targeted tissue from damage. The coolable ablation assembly damages nerve tissue to temporarily or permanently decrease nervous system input.
Claims28
A delivery device, comprising:
- an elongate body having a coolant delivery lumen;
- and
- an ablation assembly positionable in an airway of a bronchial tree, including:
- an energy emitter assembly configured to output energy to ablate targeted tissue of the bronchial tree;
- and
- a deployable element movable from a collapsed state to an expanded state, the deployable element configured to contain and circulate a coolant delivered through the coolant delivery lumen and being movable into contact with a wall of the airway,
- wherein the deployable element has a surface which is configured for optical coupling with an optical element which is configured to be positioned in the airway outside of the deployable element, the optical element facing the surface of the deployable element such that the energy emitter assembly is viewable through the surface of the deployable element with the optical element when the deployable element is in the expanded state or a partially expanded state.

An energy delivery system, comprising:
- an optical element configured for visualization in an airway of a bronchial tree;
- an elongate body having a coolant delivery lumen;
- and
- an ablation assembly coupled to the elongate body and positionable in the airway, including:
- an energy emitter assembly configured to output energy to ablate targeted tissue of the bronchial tree;
- and
- a deployable element movable from a collapsed state to an expanded state, the deployable element configured to contain and circulate a coolant delivered through the coolant delivery lumen and being movable into contact with a wall of the airway, wherein the optical element is configured to be positioned outside of the deployable element, and wherein the deployable element has a surface which is configured for optical coupling with the optical element in the airway such that the energy emitter assembly is viewable through the surface of the deployable element with the optical element when the deployable element is in the expanded state.
