Devices and methods for treatment of heart failure and associated conditions
First Claim
1. A medical device comprising:
- a first fluid status monitoring circuit configured to monitor a first fluid status indicator of a pulmonary fluid in a patient associated with pulmonary edema, wherein an increase in the first fluid status indicator correlates to an increase in pulmonary fluid associated with pulmonary edema;
a second fluid status monitoring circuit configured to monitor a separate and different second fluid status indicator of a non-pulmonary fluid, wherein an increase in the second fluid status indicator correlates to an increase in the non-pulmonary fluid;
a controller coupled to the first and second fluid status monitoring circuits, the controller configured to use information about the first and second fluid status indicators to generate a therapy control signal; and
a therapy circuit coupled to the controller to receive the therapy control signal, the therapy circuit configured to deliver therapy to the patient in response to the therapy control signal to adjust at least one of the pulmonary fluid or the non-pulmonary fluid, wherein the second fluid status indicator comprises a splanchnic measurement representative of fluid associated with a splanchnic organ.

Abstract
Devices and methods of use are described for identification, treatment, and/or management of heart failure and/or associated conditions. An exemplary device may include a first fluid status monitoring circuit configured to monitor a first fluid status indicator of a pulmonary fluid status associated with pulmonary edema, a second fluid status monitoring circuit configured to monitor a separate and different second fluid status indicator of a non-pulmonary fluid status, and a controller coupled to the first and second fluid status monitoring circuits, and a therapy circuit coupled to the controller. The controller is configured to use information about the first and second fluid status indicators to determine a therapy control signal to control a therapy, and the therapy circuit is configured to provide therapy in response to the therapy control signal to adjust at least one of the pulmonary fluid status or the non-pulmonary fluid status.

8. A method comprising:
-
monitoring a first fluid status indicator of a pulmonary fluid in a patient associated with pulmonary edema; monitoring a separate and different second fluid status indicator of a non-pulmonary fluid, wherein the second fluid status indicator comprises a splanchnic measurement representative of fluid associated with a splanchnic organ; and using information about the first and second fluid status indicators, controlling a therapy delivered to the patient to adjust at least one of the pulmonary fluid or the fluid associated with a splanchnic organ. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory device-readable medium comprising instructions that when performed by a medical device implanted in a patient, cause the device to perform acts comprising:
-
monitoring a first fluid status indicator of a pulmonary fluid in the patient status associated with pulmonary edema; monitoring a separate and different second fluid status indicator of a non-pulmonary fluid, wherein the second fluid status indicator comprises a splanchnic measurement representative of fluid associated with a splanchnic organ; and using information about the first and second fluid status indicators, providing a control signal to deliver a therapy to the patient to adjust at least one of the pulmonary fluid or the non-pulmonary fluid. - View Dependent Claims (16, 17, 18, 19)
