Abstract
Neuromodulation cryotherapeutic devices and associated systems and methods are disclosed herein. A cryotherapeutic device configured in accordance with a particular embodiment includes an elongated shaft and a cooling assembly at a distal portion of the shaft. The shaft can be configured to locate the distal portion intravascularly at a treatment site within or otherwise proximate a renal artery. The cryotherapeutic device can further include a supply lumen configured to carry liquid refrigerant toward the cooling assembly. The cooling assembly can include an applicator in fluid communication with the supply lumen and configured to deliver cryotherapeutic cooling to nerves proximate the target site when in a deployed state.
