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.
Claims25
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.
2 more elements
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.

An implantable medical system, comprising:
- an implantable sensor configured to sense blood viscosity;
- an anemia module configured to compare the blood viscosity to one or more thresholds respectively associated with one or more hematocrit levels and to determine an anemia status of a patient based on comparison of the blood viscosity to the one or more thresholds;
- and
- a therapy module configured to deliver therapy to the patient based on the anemia status or blood viscosity.
