摘要
Devices, systems, and methods for treating pulmonary conditions, such as COPD and asthma, by denervating bronchial tissue using cryoablation. In one embodiment, a device for bronchial denervation comprises: an elongate body having a distal portion and a proximal portion opposite the distal portion; a treatment element at the distal portion of the elongate body; and a first recording electrode located distal to the treatment element and a second recording electrode located proximal to the treatment element, the first and second recording electrodes being configured to record electromyograms. In one embodiment, the device includes a fluid delivery element that is within the treatment element and that has a plurality of orifices aligned with an equatorial portion of the treatment element.
