Negative Pressure Therapy System and Methods

A system for providing mechanical assistance for blood circulation and for removing fluid from a urinary tract, the system comprising:

• at least one sensor configured to detect signal(s) representative of bioelectrical impedance and communicate the signal(s) representative of the bioelectrical impedance;
• and
• a controller in communication with the at least one sensor configured to:
• receive and process the signal(s) from the at least one sensor to determine the bioelectrical impedance;
• provide a first control signal determined at least in part based on the determined bioelectrical impedance to a negative pressure source to control applying negative pressure to a urinary catheter;
• and
• provide a second control signal determined at least in part based on the determined bioelectrical impedance to a blood pump to control output of the blood pump.

A method for removing fluid from a urinary tract, the method comprising:

• monitoring a bioelectrical impedance;
• determining if the bioelectrical impedance is above, below, or at a predetermined value;
• and
• applying negative pressure to a urinary catheter to remove the fluid from the urinary tract when the bioelectrical impedance is below the predetermined value or ceasing application of the negative pressure when the bioelectrical impedance is at or above the predetermined value.
