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 status 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 status, 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 determine a therapy control signal to control a therapy; and
a therapy circuit coupled to the controller to receive the therapy control signal, the therapy circuit 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.

Abstract
Devices and methods of use for identification, treatment and/or management of heart failure and/or associated conditions. An exemplary device may include a first sensor configured to monitor a parameter indicative of a fluid level in a pulmonary circulation of a patient, a second sensor configured to monitor a parameter indicative of a fluid level in a non-pulmonary circulation of a patient, and a control system coupled to the first sensor and second sensor. The control system is configured to provide a baroreflex therapy to the patient based at least in part on the parameter indicative of a fluid level in a pulmonary circulation and the parameter indicative of a fluid level in a non-pulmonary circulation. The baroreflex therapy adjusts at least one of the fluid level in the pulmonary circulation and the fluid level in the non-pulmonary circulation.
