(c) a controller configured to increase urine production by adjusting one or more operating parameters of a negative pressure source for inducing negative pressure through the at least one ureteral catheter into the urinary tract, based at least in part upon the information determined by the one or more sensor(s).
2. The negative pressure therapy system according to claim 1 , wherein the negative pressure source alters interstitial pressure within the kidney.
3. The negative pressure therapy system according to claim 1 , wherein the controller adjusts the negative pressure to therapeutically appropriate levels.
4. The negative pressure therapy system according to claim 1 , wherein the controller adjusts the frequency with which the negative pressure source induces negative pressure.
5. The negative pressure therapy system according to claim 1 , wherein the controller induces negative pressure at two or more different pressure levels.
6. The negative pressure therapy system according to claim 1 , wherein information further comprises analyte concentration of the urine.
7. The negative pressure therapy system according to claim 1 , further comprising a thermometer for measuring urine temperature.
8. The negative pressure therapy system according to claim 1 , further comprising a flow meter for measuring the flow rate of urine through the ureteral catheter.
9. The negative pressure therapy system according to claim 1 , wherein the sensor is embedded in a wall of the at least one ureteral catheter.
10. The negative pressure therapy system according to claim 1 , wherein the sensor is in fluid communication with a drainage lumen of the at least one ureteral catheter.
11. The negative pressure therapy system according to claim 1 , wherein the sensor is positioned in a fluid collection container.
12. The negative pressure therapy system according to claim 1 , further comprising a bladder catheter, wherein the negative pressure source induces negative pressure through both the bladder catheter and the at least one ureteral catheter.
13. The negative pressure therapy system according to claim 1 , further comprising a negative pressure source for inducing negative pressure through the at least one ureteral catheter into the urinary tract.
14. The negative pressure therapy system according to claim 13 , wherein the sensor is positioned in electrical communication with internal circuitry of the negative pressure source.
15. The negative pressure therapy system according to claim 1 , further comprising a data transmitter in communication with the controller, the data transmitter being configured to provide the information from the one or more sensors to an external source.
16. The negative pressure therapy system of claim 1 , wherein the catheter is configured to be deployed in a urinary tract of a patient.
17. The negative pressure therapy system of claim 16 , wherein the patient is an animal.
