1. A method of operating an implantable medical system, the method comprising:
- sensing blood viscosity using a sensor configured for implantation within a blood vessel or heart;
comparing the blood viscosity to one or more thresholds respectively associated with one or more hematocrit levels;
determining an anemia status of a patient based on comparison of the blood viscosity to the one or more thresholds; and
controlling an electrical stimulation therapy delivered to one or both kidneys or a hypothalamus of the patient based at least in part on the anemia status.

Abstract
Methods and systems for implantably determining a patient'"'"'s anemia status and treating anemia are described. Blood viscosity is compared one or more thresholds to determine a patient'"'"'s anemia status. Therapy, in the form of electrical stimulation therapy or administration of a pharmaceutical delivered to the patient'"'"'s kidneys or hypothalamus is controlled based on the anemia status.

12. A medical system, comprising:
-
an implantable sensor including circuitry configured to sense blood viscosity and to generate a signal modulated by the blood viscosity; implantable circuitry configured to receive the blood viscosity signal and to store the blood viscosity; and an anemia module coupled to the implantable circuitry, the anemia module configured to compare the blood viscosity to one or more thresholds associated with hematocrit, to determine an anemia status of a patient based on the comparison, and to store a trend of the anemia status over time. - View Dependent Claims (13, 14, 15, 16)
