Abstract
Cryotherapeutic devices for renal neuromodulation and associated systems and methods are disclosed herein. A cryotherapeutic device configured in accordance with a particular embodiment of the present technology can include an elongated shaft having a distal portion and a supply lumen along at least a portion of the shaft. The shaft can be configured to locate the distal portion intravascularly at a treatment site proximate a renal artery or renal ostium. The supply lumen can be configured to receive a liquid refrigerant. The cryotherapeutic device can further include a cooling assembly at the distal portion of the shaft. The cooling assembly can include an applicator having a distributor in fluid communication with the supply lumen and a balloon configured to deliver cryotherapeutic cooling to nerves proximate the treatment site when the cooling assembly is in a deployed state.
