| Summary: | This invention relates generally to medical devices and methods of using same. More particularly, the invention relates to devices, systems, and methods for altering a patient's temperature and blood gas concentration levels, such as blood oxygen levels.
An endovascular catheter device capable of heat and gas exchange with a patient's bloodstream comprises a catheter shaft, a heat exchanger, and a gas exchange element. The heat exchanger and the gas exchange element are in fluid communication with one or more internal lumens of the catheter shaft. The catheter shaft may be connected to a control system that permits a heat exchange fluid to be delivered to the heat exchanger, and that permits a gas to be delivered to the gas exchange element. The catheter device may also comprise one or more flow disruption devices to disrupt the laminar flow of blood around the catheter device. The catheter device may be used to cool and oxygenate a patient's blood, and improve organ function. |
