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 operation of the first and second mechanical circulatory support systems. 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application Serial No. 16 / 406,896, filed May 8, 2019, entitled "Use of Cardiac Assist Device to Improve Kidney Function," which The entire content of the application is incorporated herein by reference. Background technique [0003] The kidneys play a central role in controlling arterial hydraulic pressure in the body. They regulate renal output by altering water excretion (diuresis) and by altering salt excretion (natriuresis). This regulation is reflected in the renal output curve ( figure 1 ), where urine output varies according to arterial pressure. Under normal conditions, the kidneys automatically adjust themselves to increase or decrease urine output and renal blood flow in response to increases or decreases in blood pressure or blood flow velocity, or changes in salt concentration. However, impairment or other changes in renal function may impair automatic adjus...
