Intravenous infusion catheter assemblies and methods of use are described herein. The catheter assembly may include an elongate body having a proximal end and a distal end with an expandable occlusion element disposed on the elongate catheter body. The catheter may include a first infusion lumen extending to a proximal infusion port positioned proximal to the occlusion element on the catheter body and a second infusion lumen extending to a distal infusion port. Some embodiments may use a suction lumen extending to at least one suction port. When the catheter is introduced into the vasculature of the patient, the aspiration port may be positioned in the superior vena cava or right atrium of the patient to draw blood, the distal infusion port positioned to direct a normal or high temperature fluid toward the heart of the patient, and the proximal infusion port positioned to create a flow of cryogenic fluid in the brain vasculature of the patient. 在本文中描述静脉输注导管组件和使用方法。导管组件可以包括细长主体，细长主体具有近端和远端，其中可扩张闭塞元件设置于细长导管主体上。
