  • Infusion catheter and methods of use
    Patent number: 12097345
    Abstract: Venous infusion catheter assemblies and methods of use are described herein. A catheter assembly may comprise an elongated body having a proximal end and a distal end, with an expandable occlusion element disposed on the elongated catheter body. A catheter may include a first infusion lumen extending to a proximal infusion port positioned on the catheter body proximally of the occlusion element 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 vasculature of a patient, the suction port may be positioned in the patient's superior vena cava or right atrium to draw blood, the distal infusion port is positioned to direct normothermic or hyperthermic fluid toward the patient's heart, and the proximal infusion port is positioned to create a flow of hypothermic fluid in the patient's cerebral vasculature.
