Abstract
A pulmonary treatment system includes a compact configuration for delivery to an airway of a patient. An energy delivery system of the pulmonary treatment system delivers ultrasound energy to target nerve tissue in or along an airway wall of the airway radially outward from surface tissue to reduce airway resistance in a downstream airway. The pulmonary treatment system may protect tissue in the airway wall of the airway located between the target nerve tissue and the ultrasound energy delivery system by a coolant system that may also act as a coupling fluid for the emitted ultrasound energy.
Claims9
A pulmonary treatment system, comprising:
- an elongate body;
- and
- an ultrasound energy delivery assembly coupled to a distal end of the elongate body and being positionable into an airway of a patient, the airway having first and second interior surfaces on opposing sides thereof, wherein the ultrasound energy delivery assembly comprises an apposition member, a fluid conduit having an elongate portion extending along an exterior surface of the apposition member, and an ultrasound energy delivery element extending along the elongate portion of the fluid conduit, the ultrasound energy delivery assembly being movable from a delivery state to a deployed state,
- wherein the apposition member is configured to urge the fluid conduit closer to and into contact with the first interior surface of the airway when the ultrasound energy delivery assembly is in the deployed state to position the ultrasound delivery element closer to a treatment site located radially outward from the first interior surface,
- wherein, in the deployed state, the elongate portion of the fluid conduit with the ultrasound energy delivery element extends longitudinally along the exterior surface of the apposition member and parallel to a longitudinal axis of the apposition member, the ultrasound delivery element being positioned outside of the fluid conduit between the fluid conduit and the apposition member such that the ultrasound delivery element is completely or substantially concealed between the fluid conduit and the apposition member, and
- wherein the ultrasound energy delivery element is configured to deliver ultrasound energy to the treatment site.
