  • Patent number: 7144407
    Abstract: An intra-aortic balloon pump catheter system (apparatus and method) includes a pumping element for pumping a patient's blood and one or more heat exchange for exchanging heat with the patient's blood to provide efficient temperature control of the patient. The catheter may also provide access to the patient's central venous system through one or more infusion lumens and infusion ducts. An elongate body defines an inflation lumen that conveys an inflation fluid to and from the pumping element, and an inflow lumen and an outflow lumen that supply heat exchange fluid to and from each heat exchange element. The pumping element may include an everting pumping balloon that expands out of a cavity in the elongate body after insertion of the catheter. The catheter may have an internal heating element that heats or cools the heat exchange fluid.

  • Patent number: 6516224
    Abstract: A method for treating cardiac arrest includes defibrillating the patient and/or ventilating the patient and/or administering a cardiac arrest drug such as epinephrine to resuscitate the patient, and then cooling the patient's body temperature using one or more cooling catheters positioned in the central venous system of the patient and/or particularly cooling the patient's brain temperature using a catheter advanced into the aortic arch or into the carotid artery whereby a bolus of cold saline solution is introduced into the blood supplied to the brain to lower the brain temperature quickly, and further cooling or maintaining the brain temperature at a desired level by pumping coolant in a closed circuit formation between the catheter and the coolant source to remove heat from the blood supplied to the patient's brain.

  • Patent number: 5875782
    Abstract: Methods and devices for revascularization of a patient's coronary artery system which obviate the need to place the patient on cardiopulmonary bypass. A method is provided for revascularizing a patient while the-heart is beating, and includes performing at least one minimally invasive coronary artery bypass graft procedure, or other cardiac surgical procedure, and contemporaneously performing at least one catheter-based procedure in at least one coronary artery. The catheter-based procedure(s) may be either therapeutic or diagnostic or both, and may involve delivering at least one catheter to a coronary artery via a surgical or percutaneous opening in the thoracic cavity or via a percutaneous opening at a location peripheral to the thoracic cavity. The catheter-based procedure or procedures is performed contemporaneously with the bypass graft procedure, and specifically prior to, during, or after anesthetizing the patient for purposes of the bypass graft procedure.

  • Patent number: 5636634
    Abstract: A steerable first catheter directs the introduction of a guide sheath, which can otherwise be free of any onboard steering mechanism. The guide sheath, in turn, directs the introduction of the electrode-carrying second catheter, which can likewise be free of any onboard steering mechanism. Use of a guide sheath positioned by a separate, dedicated steering catheter to guide a separate, dedicated electrode-carrying catheter results in a significant reduction in the overall size of the system components.
