Abstract:

A mechanical circulatory support system for a heart having a cooling element and a method for using the system to treat the effects of a cardiac episode. The support system has a pump having a distal end and a proximal end, the pump comprising a rotor, the rotor having at least one blade. The system also has a catheter having a distal end, a proximal end, and inner surface, and an outer surface, the catheter extending proximally of relative to the pump housing. The outer surface of the catheter is configured to contact blood when disposed within patient vasculature. The outer surface of the catheter comprises a heat transfer surface configured for cooling blood that comes in contact with the outer surface. The cooling element can be either a helix or double helix extending along a catheter surface or a Peltier element on the surface. The support system is operated to provide a temperature selected to cool the circulating blood in contact with the outer surface of the catheter to a temperature selected to reduce or prevent an effect of a cardiac episode

Abstract:

Systems and methods for improving kidney function. A first mechanical circulatory support system (MCS) is introduced in a patient's heart, and a second mechanical circulatory support system is introduced in a patient's inferior vena cava or renal vein. The second mechanical circulatory support system is operated while the first mechanical circulatory support system is operating. A renal parameter is monitored during. Combined operation of the two mechanical circulatory support systems results in a change in renal parameter, e.g. pressure drop in the renal vein, indicating an improvement in kidney function. Once the renal parameter is determined to be below a target threshold, operation of the second mechanical circulatory support device is stopped.
