A system for minimizing misalignment notifications for a TETS having an implantable blood pump, an external controller having a power source and a processing circuitry, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and the implantable blood pump. The implantable controller having a power source configured to receive power from the receiving coil. The processing circuitry may be configured to: operate in a first mode where an alert is generated when a power efficiency transfer between the transmission coil and the receiving coil is below a first predetermined threshold; and operate in a second mode where the alert is only generated when the power remaining in the power source for the implantable controller is below a first predetermined power source threshold.

A system for removing fluid from a urinary tract includes at least one sensor configured to detect signal(s) representative of pulmonary artery pressure and communicate signal(s) representative of the pulmonary artery pressure and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the pulmonary artery pressure is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the pulmonary artery pressure signal(s) received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter to remove fluid from a urinary tract when the pulmonary artery pressure is above the predetermined value and to cease applying negative pressure when the pulmonary artery pressure is at or below the predetermined value.

A system for removing fluid from a urinary tract includes: at least one sensor configured to detect signal(s) representative of bioelectrical impedance and communicate signal(s) representative of the impedance; and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the impedance is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the signal(s) representative of the impedance received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter when the impedance is below the predetermined value and to cease applying negative pressure when the impedance is at or above the predetermined value.
