神经调节冷冻治疗设备和相关系统和方法

Abstract

披露了神经调节冷冻治疗设备和相关的系统。根据本技术的特定实施例配置的冷冻治疗设备可以包括具有远侧部分的杆以及沿着至少一部分所述的杆的供应腔。杆可以配置为在血管内将远端部分置于靠近肾动脉或肾口的治疗部位。供应腔可以配置为接收液态制冷剂。冷冻治疗设备可以进一步包括位于杆的远侧部分的冷却组件。冷却组件可以包括与供应腔之间液体连通的施放器,施放器配置为在冷却组件处于展开状态时向目标部位附近的神经递送低温冷却。
Neuromodulation cryotherapeutic devices 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 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 in fluid communication with the supply lumen and configured to deliver cryotherapeutic cooling to nerves proximate the target site when the cooling assembly is in a deployed state.
