  • Publication number: 20240148952
    Abstract: Disclosed are systems and methods for hyperthermic cancer treatment. For example, a system can include a heat exchanger, a control module, a primary fluid delivery line (“FDL”), an intravenous catheter, and a peristaltic pump. The control module can include at least a hydraulic system configured to provide a temperature-controlled fluid. The primary FDL can be configured to convey the temperature-controlled fluid to the heat exchanger as a supply fluid and back to the hydraulic system as a return fluid. The intravenous catheter can include a primary lumen configured to convey blood of the patient to the heat exchanger as well as a secondary lumen configured to convey the blood back to the patient using the peristaltic pump. The catheter can also include a thermistor for determining a core body temperature of the patient to ensure the patient is in a hyperthermic state before administering a cancer treatment to the patient.

  • Publication number: 20230405205
    Abstract: A system for extracorporeal blood temperature control includes a heat exchanger configured to cool a circulated fluid, a thermal exchange module including a first volume fluidly isolated from a second volume, a fluid pump, a blood pump, and a controller. The fluid pump can pump the circulated fluid through the heat exchanger and the first volume of the thermal exchange module. The fluid pump can establish a negative pressure within the first volume of the thermal exchange module The blood pump can pump blood through a first blood flow line, the second volume of the thermal exchange module, and a second blood flow line. The controller can cool the blood by controlling thermal exchange between the circulated fluid pumped through the first volume of the thermal exchange module and the blood pumped through the second volume of the thermal exchange module.
