Decongestive therapy titration for heart failure patients using implantable sensor
First Claim
1. A method for assessing decongestive therapy delivered to a heart failure patient, comprising:
- sensing, from within the patient, a physiologic parameter indicative of the patient'"'"'s diuresis status;
determining if a target level of patient diuresis has been achieved based on a relationship between the sensed physiologic parameter and a threshold developed for the patient; and
producing an output in response to determining that the target level of patient diuresis has been achieved.

Abstract
Assessing decongestive therapy delivered to a heart failure patient involves use of an implantable sensor configured to sense a physiologic parameter indicative of the patient'"'"'s diuresis status and a processor coupled to the implantable sensor. The sensor may comprise a thoracic fluid sensor, a heart sounds sensor, a cardiac chamber or arterial pressure sensor, a respiration sensor, or a blood chemistry sensor, for example. The processor is configured to determine if a target level of patient diuresis has been achieved based on a relationship between the sensed physiologic parameter and a threshold developed for the patient, and to produce an output in response to determining that the target level of patient diuresis has been achieved. The processor may be disposed in an implantable housing, in a patient-external housing, or in a network server system.

15. A method for assessing a therapy delivered to a heart failure patient, comprising:
-
sensing, from within the patient, a physiologic parameter indicative of the patient'"'"'s status responsive to the therapy; determining if a target level of therapy benefit to the patient has been achieved based on a relationship between the sensed physiologic parameter and a threshold developed for the patient; and producing a first output in response to determining that the target level of patient benefit has been achieved and a second output in response to determining that the patient is subject to over-therapeuting. - View Dependent Claims (16, 17, 18)
