AI Technical Summary
Existing systems fail to effectively improve kidney function, particularly in cases of vascular disease, and may even damage kidneys by maintaining high pressure states, while current monitoring methods do not enhance kidney output or protect against toxicity.
A dual-pump system is employed, where a first blood pump unloads the heart to increase arterial pressure upstream of the kidney and a second blood pump decreases venous pressure downstream, modulating the pressure gradient across the kidney to enhance blood flow and stimulate humoral factor release, while monitoring renal parameters to determine optimal pump operation.
The system increases kidney output, protects against toxicity, and safely weans patients off support by adjusting pump operation based on renal parameters, ensuring adequate kidney function is regained without prolonged high pressure.
