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.

Abstract: A catheter includes a shaft having a proximal end, a distal end, and a central lumen extending continuously from the proximal end to the distal end. A hypotube forms a proximal region of the shaft, and a polymer tube forms a distal region of the shaft. A periphery of the hypotube is cut in a pattern which provides a decreasing stiffness in a proximal-to-distal direction, and in some embodiments the polymer tube is reinforced by a wire embedded over at least a portion of the polymer tube's length. A guidewire lumen is disposed at or near the distal end of the catheter and extends for a portion of the catheter's length. The catheter may be used for aspiration, device delivery, or other purposes in a patient's vasculature.

Abstract: A system for connection to a catheter to aspirate clot from the vasculature of a patient includes a vacuum console and a canister assembly which can be removably mounted in a mounting region of the vacuum console. The canister assembly includes a clear canister with an interior and an open top. A lid is removably attachable over the open top of the clear canister, and the clear canister has a vacuum port and a pressure sensing port each formed in a wall of the canister. The vacuum port aligns with a vacuum connector on the enclosure and the pressure sensing port aligns with a pressure sensing connector on the enclosure when the canister assembly is mounted on the mounting region of the vacuum console. The clear canister has a filter plate configured to be suspended in the interior of the clear canister at a location mid-way between the open top and a bottom to separate clot from blood as they are aspirated from the catheter.
