Abstract: An improved system and method of endobronchial imaging of lung nodules comprises the introduction of a perfluorocarbon (PFC) liquid into pulmonary passages of the lungs, the introduction of which enables better coupling between an endobronchial ultrasonic imaging system and a target tissue site within the pulmonary passages of the lungs, the improved coupling between the ultrasonic imaging system and a target tissue site being imparted by the removal (at least in part) the air interface present between the ultrasonic imaging system and the surface of the target tissue site. Furthermore, the unique properties of perfluorocarbon liquids (for example, the properties of superb biocompatibility, high affinity for dissolving oxygen, and extremely low surface tension) further position these substances to be particularly well-suited for this application.

Abstract: In one example, a medical device may include a handle including a proximal portion and a distal portion, and the proximal portion may pivot relative to the distal portion. The medical device may also include an insertion portion coupled to the distal portion of the handle and configured to be positioned within a body lumen; and an articulation wire extending from the handle through the insertion portion. Pivoting of the proximal portion of the handle relative to the distal portion of the handle may move the articulation wire relative to the insertion portion to bend a distal portion of the insertion portion.

Abstract: Plasma delivery tips of medical-grade plasma generating devices are configured to exclude potential contaminants while operating within body cavities. In some embodiments, delivery tips are provided with an antechamber, which is optionally filled by pressure of ionizing gas to prevent contamination. Some embodiments are provided with one or more interior and/or exterior valves configured to prevent proximal ingress of contamination to the longitudinal position of the discharge electrode, or at all into the gas delivery lumen. In some embodiments, an expandable distal section of the plasma delivery tip acts as a valve which seals when closed, and when open expands to generate an inflated antechamber into which plasma is delivered.

Abstract: A method of performing bronchial denervation of a bronchus having bronchial nerves along a portion thereof is provided. The method includes providing a cryoablation device having multiple electrodes capable of delivering electrical energy and measuring impedance. At least one bronchial nerve is stimulated with electrical energy. The electrical signals from the at least one bronchial nerve are recorded to provide a first value representative of nerve function. Cryogenic treatment energy is applied to form ice in the bronchus having a thickness to encapsulate the at least one bronchial nerve to cause a reduction in nerve function. The at least one bronchial nerve is restimulated with electrical energy. The electrical signals are recorded from the restimulated at least one bronchial nerve to provide a second value that represents diminished nerve function. The first value and the second value are compared to provide an assessment of the reduction in nerve function.
